Web Analytics

A marketplace app connects multiple buyers and sellers, service providers and customers, or businesses and consumers through a single digital platform. Unlike a standard ecommerce app that sells products from one business, a marketplace app has to support several parties, each with different workflows, permissions, transactions, and expectations.

So, how much does it cost to build a marketplace app?

The cost of building a marketplace app typically falls between $15,000 and $500,000 or more, depending on the marketplace model, feature set, platforms, design complexity, integrations, security requirements, development team, and geographic location of the development team.

For an early-stage marketplace with essential features, an MVP can often be developed for approximately $15,000 to $40,000. A more sophisticated marketplace with buyer and seller apps, advanced search, payments, vendor management, messaging, analytics, logistics, and personalized experiences can cost $40,000 to $150,000 or more. Large enterprise marketplace platforms with complex integrations, automation, AI, advanced security, multiple regions, and custom infrastructure can exceed $250,000 to $500,000.

In India, development costs can be lower than in the United States, United Kingdom, or Western Europe, although the final budget depends heavily on the expertise and specialization of the development team.

The important point is that there is no single marketplace app development price. A marketplace is an ecosystem, not simply a mobile application.

This guide explains the major marketplace app development costs, what influences the budget, how much individual features can cost, how long development can take, and how businesses can structure a marketplace MVP without overspending.

Marketplace App Development Cost at a Glance

The following estimates can help establish an initial budget.

Marketplace App Type Estimated Cost Approximate Timeline
Basic Marketplace MVP $15,000 to $40,000 3 to 5 months
Standard Marketplace $40,000 to $100,000 5 to 8 months
Advanced Marketplace $100,000 to $250,000 8 to 12 months
Enterprise Marketplace $250,000 to $500,000+ 12 to 18+ months
Highly Customized Global Marketplace $500,000+ 18+ months

These are planning ranges rather than fixed quotations. A marketplace focused on selling physical products can have very different requirements from a marketplace for freelancers, rentals, real estate, appointments, transportation, or professional services.

For example, a simple product marketplace may need:

  • Buyer registration
  • Seller registration
  • Product listings
  • Search
  • Shopping cart
  • Checkout
  • Payment processing
  • Order management
  • Reviews
  • Notifications
  • Seller dashboard
  • Admin dashboard

A service marketplace may instead need:

  • Provider profiles
  • Availability calendars
  • Service packages
  • Location search
  • Appointment scheduling
  • Time slots
  • Customer requests
  • Provider acceptance
  • Messaging
  • Cancellation rules
  • Reviews
  • Payments
  • Payouts

The difference in functionality can substantially change the development budget.

What Is a Marketplace App?

A marketplace app is a digital platform where independent sellers, service providers, businesses, creators, or other participants can offer products or services to customers.

The marketplace operator provides the technology and business infrastructure that enables transactions.

Examples of marketplace models include:

  • Product marketplaces
  • Service marketplaces
  • B2B marketplaces
  • C2C marketplaces
  • Rental marketplaces
  • Real estate marketplaces
  • Food marketplaces
  • Freelancer marketplaces
  • Job marketplaces
  • Travel marketplaces
  • Booking marketplaces
  • Digital product marketplaces
  • Used goods marketplaces
  • Automotive marketplaces
  • Healthcare service marketplaces
  • Education marketplaces

A marketplace usually has at least three major components:

  1. Customer or buyer experience
  2. Seller or service provider experience
  3. Marketplace administration system

Depending on the business model, the seller experience may be a separate mobile app, a web dashboard, or both.

The backend connects all these components.

This makes marketplace development more complex than building a conventional single-vendor ecommerce application.

Why Marketplace Apps Cost More Than Standard Ecommerce Apps

A standard ecommerce application generally represents one business.

The business controls:

  • Product catalog
  • Pricing
  • Inventory
  • Orders
  • Customers
  • Promotions
  • Payments
  • Fulfillment

A marketplace has multiple independent sellers.

Each seller may have:

  • Different products
  • Different prices
  • Different inventory
  • Different shipping policies
  • Different cancellation rules
  • Different tax information
  • Different payout information
  • Different fulfillment methods

The marketplace therefore needs a system that separates seller data while still presenting a unified experience to customers.

For example, imagine a customer purchases three products from three different sellers.

The system may need to determine:

  • Which seller receives each order item
  • How much commission the marketplace earns
  • How much each seller receives
  • Which shipping provider handles each item
  • Whether each item ships separately
  • How taxes are calculated
  • What happens if one item is cancelled
  • How refunds are distributed
  • When sellers receive payouts

These requirements introduce additional backend logic.

As a result, marketplace app development usually involves more engineering than a simple ecommerce application.

Average Cost to Build a Marketplace App

The average marketplace app development cost depends primarily on complexity.

Basic Marketplace App

A basic marketplace MVP generally costs between $15,000 and $40,000.

It may include:

  • Customer registration
  • Seller registration
  • Seller profiles
  • Product or service listings
  • Basic search
  • Categories
  • Product details
  • Cart
  • Checkout
  • Payment gateway
  • Order management
  • Basic reviews
  • Push notifications
  • Seller dashboard
  • Admin dashboard

This approach is suitable for validating a business idea.

The objective is not to build every possible feature.

The objective is to prove that:

  • Sellers are willing to join
  • Customers are willing to use the platform
  • Transactions can happen successfully
  • The marketplace can generate revenue
  • Users return after their first transaction

Standard Marketplace App

A standard marketplace can cost approximately $40,000 to $100,000.

It typically includes more sophisticated functionality.

Features may include:

  • Advanced search
  • Filters
  • Seller verification
  • Seller analytics
  • Multiple payment methods
  • Automated commissions
  • Seller payouts
  • Coupons
  • Promotions

  • Messaging
  • Location-based search
  • Order tracking
  • Returns
  • Refund workflows
  • Ratings
  • Reviews
  • Customer support
  • Advanced admin controls
  • Analytics
  • Marketing integrations

This level of application is more appropriate when the business model has already been validated or when the marketplace needs a stronger launch experience.

Advanced Marketplace App

An advanced marketplace can cost $100,000 to $250,000 or more.

It may include:

  • Separate buyer and seller mobile applications
  • iOS and Android applications
  • Advanced web application
  • Real-time messaging
  • Geolocation
  • Dynamic pricing
  • Recommendation systems
  • AI-powered search
  • Fraud detection
  • Advanced seller verification
  • Automated settlements
  • Subscription plans
  • Seller advertising
  • Loyalty programs
  • Multi-currency support
  • Multi-language support
  • Advanced logistics
  • Third-party ERP integrations
  • CRM integrations
  • Business intelligence dashboards
  • Custom reporting
  • Advanced security architecture

At this stage, the marketplace becomes a substantial software product rather than a simple mobile application.

Enterprise Marketplace App

Large marketplace platforms can require $250,000 to $500,000 or more.

The actual budget can be substantially higher for global platforms.

Enterprise requirements may include:

  • Multiple countries
  • Multiple currencies
  • Multiple languages
  • Regional tax systems
  • Complex payment flows
  • High traffic
  • Large product catalogs
  • Enterprise seller management
  • Advanced permissions
  • Multiple fulfillment models
  • Warehouse integrations
  • ERP integrations
  • CRM integrations
  • Data warehouses
  • Advanced analytics
  • AI recommendations
  • Fraud prevention
  • High availability
  • Disaster recovery
  • Extensive security controls
  • Compliance requirements
  • Dedicated DevOps
  • Automated testing
  • Continuous deployment

At this level, development cost is influenced heavily by architecture and infrastructure.

Marketplace App Development Cost by Complexity

Another way to understand the budget is to divide the project into functionality levels.

Complexity Estimated Cost
Basic MVP $15,000 to $40,000
Medium Complexity $40,000 to $100,000
Advanced $100,000 to $250,000
Enterprise $250,000 to $500,000+

The difference between these categories is primarily the number and complexity of workflows rather than the number of screens.

Ten simple screens may cost less than five screens containing complicated transaction logic.

For example, a seller payout system can require considerably more engineering than a static information page.

Marketplace App Development Cost in India

India is one of the most common destinations for outsourced software development because businesses can access developers across multiple skill levels and technology stacks.

Approximate marketplace development budgets in India may look like this:

Project Type Estimated Cost in India
Basic MVP ₹12 lakh to ₹35 lakh
Standard Marketplace ₹35 lakh to ₹85 lakh
Advanced Marketplace ₹85 lakh to ₹2.1 crore
Enterprise Marketplace ₹2.1 crore to ₹4.2 crore+

These ranges are broad because development companies differ substantially in:

  • Experience
  • Team structure
  • Technology expertise
  • Project management
  • QA processes
  • Security practices
  • Design capabilities
  • DevOps capabilities
  • Industry specialization

A low-cost quotation does not automatically mean the project will have a lower total cost.

Poor architecture can create expensive technical debt later.

Marketplace App Development Cost in the United States

Development rates in the United States are generally higher because of labor costs and market rates for experienced software engineers, designers, architects, QA engineers, and project managers.

A marketplace project may cost approximately:

  • MVP: $40,000 to $100,000
  • Standard: $100,000 to $200,000
  • Advanced: $200,000 to $400,000
  • Enterprise: $400,000 to $750,000+

These figures are indicative rather than fixed market prices.

A US based development company may charge more while providing advantages such as close timezone alignment, stronger local communication, domain expertise, or enterprise consulting.

Marketplace App Development Cost in the UK

UK development budgets can also vary significantly.

A marketplace MVP may cost approximately £30,000 to £70,000, while larger marketplace applications can move into six-figure budgets.

Factors include:

  • Developer seniority
  • Product design requirements
  • Integrations
  • Security requirements
  • Compliance
  • Infrastructure
  • Testing
  • Project management
  • Post-launch support

Marketplace App Development Cost in Europe

European development rates vary considerably by country.

Development teams in Western Europe may charge substantially more than teams in Eastern or Southern Europe.

A marketplace project can range from approximately €30,000 for a relatively focused MVP to €300,000 or more for a complex enterprise platform.

The most important comparison is not simply hourly rate.

Businesses should evaluate total project cost, delivery quality, communication, architecture, testing, and long-term support.

Major Factors That Affect Marketplace App Development Cost

Several factors influence the final development budget.

1. Marketplace Business Model

The first question is what kind of marketplace you are building.

A product marketplace, service marketplace, rental marketplace, and B2B marketplace have different workflows.

For example, a rental marketplace may need:

  • Availability calendars
  • Booking dates
  • Security deposits
  • Damage policies
  • Pickup and return workflows

A freelancer marketplace may require:

  • Proposals
  • Milestones
  • Contracts
  • Time tracking
  • Escrow
  • Dispute management

A real estate marketplace may need:

  • Property listings
  • Maps
  • Agent profiles
  • Virtual tours
  • Lead management
  • Appointment scheduling

The business model affects the technical architecture.

2. Number of Platforms

A marketplace may require:

  • iOS app
  • Android app
  • Seller app
  • Customer app
  • Web application
  • Seller dashboard
  • Admin dashboard

Building each platform independently increases development cost.

A business should therefore determine which platforms are essential at launch.

For many startups, a practical approach is:

  • Cross-platform mobile application
  • Responsive seller dashboard
  • Web-based admin panel

This can reduce initial development costs.

3. UI and UX Design

Design is another important cost factor.

A marketplace needs more than attractive screens.

The UX must make complex workflows understandable.

The design may cover:

  • Customer onboarding
  • Seller onboarding
  • Product discovery
  • Search
  • Filtering
  • Product details
  • Cart
  • Checkout
  • Order tracking
  • Seller management
  • Notifications
  • Messaging
  • Reviews
  • Account management
  • Payment management

A marketplace with poor UX can suffer from abandoned carts and low seller adoption even if the backend works correctly.

4. Backend Development

The backend is one of the largest components of marketplace development.

It manages:

  • Users
  • Sellers
  • Products
  • Services
  • Orders
  • Payments
  • Commissions
  • Payouts
  • Inventory
  • Reviews
  • Notifications
  • Promotions
  • Messaging
  • Analytics

The backend also handles authentication, permissions, APIs, database operations, business rules, and integrations.

Complex marketplace logic often makes backend engineering one of the most expensive parts of the project.

5. Seller Management

Seller functionality is central to a marketplace.

A seller may need to:

  • Register
  • Verify identity
  • Add business information
  • Upload documents
  • Create listings
  • Edit listings
  • Manage inventory
  • Manage prices
  • View orders
  • Process returns
  • Communicate with customers
  • Track earnings
  • Request payouts
  • View analytics

The more control sellers receive, the more complex the seller dashboard becomes.

6. Buyer Functionality

Customers may need:

  • Registration
  • Social login
  • Search
  • Categories
  • Filters
  • Product comparison
  • Wishlist
  • Cart
  • Checkout
  • Payment
  • Order tracking
  • Reviews
  • Messaging
  • Notifications
  • Support
  • Returns
  • Refunds

A simple marketplace can launch with fewer features and add advanced functionality later.

7. Admin Panel

The admin panel is often underestimated.

A marketplace administrator needs to control the ecosystem.

An admin dashboard can include:

  • User management
  • Seller management
  • Product management
  • Category management
  • Order management
  • Payment management
  • Commission management
  • Refund management
  • Content management
  • Review moderation
  • Seller verification
  • Reports
  • Analytics
  • Notifications
  • Promotions
  • Support tickets
  • Dispute management

An advanced marketplace may require role-based administration.

For example:

  • Super administrator
  • Finance administrator
  • Customer support manager
  • Seller manager
  • Content manager
  • Operations manager

Each role can have different permissions.

Marketplace App Feature Cost Breakdown

Understanding individual features makes budgeting easier.

  • Price
  • Location
  • Rating
  • Availability
  • Seller
  • Attributes

Basic search is relatively simple.

Advanced search may use dedicated search technologies and indexing systems.

Estimated cost:

$2,000 to $12,000

AI-powered semantic search can increase the cost further.

Shopping Cart

The cart needs to handle marketplace-specific rules.

For example, a customer may have products from multiple sellers.

The system must understand:

  • Seller ownership
  • Product quantities
  • Shipping
  • Taxes
  • Discounts
  • Seller-specific restrictions

Estimated cost:

$1,500 to $5,000

Checkout

Checkout is more complicated in a marketplace than in many single-store applications.

It can include:

  • Address selection
  • Shipping options
  • Tax calculation
  • Coupon codes
  • Payment method
  • Order summary
  • Seller split
  • Delivery estimates

Estimated cost:

$2,000 to $8,000

Payment Gateway Integration

A marketplace needs to collect money from customers and distribute money according to its business model.

The payment system may involve:

  • Customer payment
  • Marketplace commission
  • Seller share
  • Payment processing fees
  • Taxes
  • Refunds
  • Partial refunds
  • Payouts

Estimated development cost:

$2,000 to $10,000

Payment provider fees are separate from development costs.

Businesses should review the current pricing, supported countries, settlement rules, and marketplace capabilities of their selected payment provider.

Marketplace Commission System

Commission is often the primary monetization model for marketplaces.

For example, a platform might charge:

  • Percentage commission
  • Fixed fee
  • Seller subscription
  • Listing fee
  • Transaction fee
  • Combination of fees

The system needs to calculate commissions accurately.

For a $100 transaction:

  • Seller receives an amount
  • Marketplace receives its commission
  • Payment processor may charge a fee
  • Taxes may apply
  • Refunds may change the settlement

Estimated development cost:

$2,000 to $8,000

Seller Payout System

Seller payouts require careful financial logic.

The system may support:

  • Automatic payouts
  • Scheduled payouts
  • Manual payouts
  • Minimum payout thresholds
  • Pending balances
  • Refund deductions
  • Commission deductions
  • Payment status

Estimated cost:

$3,000 to $12,000

This component should be designed carefully because financial errors can damage trust with sellers.

Search $2,000 to $12,000
Messaging $3,000 to $15,000
Notifications $1,000 to $4,000
QA and Testing $4,000 to $20,000
DevOps $2,000 to $15,000

Not every project needs every component at the upper end of these ranges.

These numbers also should not simply be added together because several activities overlap.

Cost of Building Buyer and Seller Apps Separately

One of the biggest decisions is whether buyers and sellers should use the same application.

One App for Buyers and Sellers

This approach provides:

  • Lower initial development cost
  • Fewer applications to maintain
  • Faster MVP development

However, the interface can become complicated.

Users may see functionality they do not need.

Separate Buyer and Seller Apps

This approach provides:

  • Cleaner UX
  • Specialized workflows
  • Better seller tools
  • Easier feature expansion

However, it increases development and maintenance costs.

A common compromise is to create:

  • Customer mobile app
  • Seller web dashboard
  • Admin web dashboard

The seller can later receive a dedicated mobile app if usage justifies it.

Native vs Cross-Platform Marketplace App Development

Technology selection also influences cost.

Native Development

Native development means creating separate applications using platform-specific technologies.

For iOS, this can involve Swift.

For Android, Kotlin is commonly used.

Advantages include:

  • Platform-specific performance
  • Strong platform integration
  • Greater control
  • Access to native APIs

Disadvantages include:

  • Higher development cost
  • Separate codebases
  • More maintenance
  • Longer development time

Cross-Platform Development

Frameworks such as Flutter and React Native can allow teams to share significant portions of application code across platforms.

Advantages include:

  • Lower initial development cost
  • Faster development
  • Shared code
  • Easier maintenance

Cross-platform development can be particularly useful for startups testing a marketplace concept.

However, technology choice should depend on the application’s requirements rather than cost alone.

Progressive Web App for a Marketplace

A Progressive Web App can provide marketplace functionality through the web.

Potential advantages include:

  • Faster deployment
  • No initial app store dependency
  • Shareable URLs
  • Easier updates
  • Lower initial development cost

PWAs can be particularly useful for:

  • Product discovery
  • Seller dashboards
  • B2B marketplaces
  • Local marketplaces

However, some mobile-specific functionality may require native applications.

Marketplace App Development Timeline

The development timeline depends on complexity.

A basic marketplace MVP may require approximately:

3 to 5 months

A standard marketplace may require:

5 to 8 months

An advanced marketplace may require:

8 to 12 months

An enterprise marketplace can require:

12 to 18 months or longer

A typical development process includes:

Phase 1: Discovery

1 to 3 weeks

Activities include:

  • Business analysis
  • User research
  • Feature definition
  • Competitor research
  • Technical planning

Phase 2: UX and UI

3 to 8 weeks

Activities include:

  • User flows
  • Wireframes
  • Design system
  • Prototype
  • Visual design

Phase 3: Development

8 to 24+ weeks

Activities include:

  • Frontend

  • Integrations

Phase 4: Testing

3 to 8 weeks

Activities include:

  • Functional testing
  • Device testing
  • Security testing
  • Performance testing
  • User acceptance testing

Phase 5: Deployment

1 to 3 weeks

Activities include:

  • Production setup
  • App store preparation
  • Monitoring
  • Analytics
  • Launch

Development and testing often overlap rather than happening as completely separate phases.

Cost of UI/UX Design for a Marketplace App

Marketplace UI/UX design can cost approximately:

$4,000 to $20,000+

The number of screens is one factor.

The number of workflows is more important.

A marketplace might have dozens of screens for:

  • Customers
  • Sellers
  • Administrators
  • Support staff

Designers need to understand the differences between these user roles.

Important UX considerations include:

  • Easy product discovery
  • Fast checkout
  • Trust signals
  • Seller information
  • Clear pricing
  • Reviews
  • Availability
  • Delivery information
  • Cancellation policies

Marketplace UX is heavily connected to conversion.

Cost of Backend Development

Backend development can represent a major percentage of the total budget.

A marketplace backend needs to support:

  • Authentication
  • User roles
  • Seller management
  • Catalog management
  • Inventory
  • Orders
  • Payments
  • Commissions
  • Payouts
  • Reviews
  • Messaging
  • Notifications
  • Analytics

Estimated backend cost:

$10,000 to $50,000+

Enterprise systems may require considerably more.

Cost of Database Development

A marketplace can contain large amounts of structured data.

Common entities include:

  • Users
  • Sellers
  • Products
  • Categories
  • Orders
  • Order items
  • Payments
  • Transactions
  • Reviews
  • Messages
  • Coupons
  • Promotions
  • Payouts

The database architecture should be designed for future scale.

Poor database design can create performance problems as the marketplace grows.

Cloud Hosting Costs

After development, the marketplace needs infrastructure.

Possible costs include:

  • Cloud servers
  • Database hosting
  • Object storage
  • CDN
  • Image processing
  • Backups
  • Monitoring
  • Logging
  • Email services
  • Notification infrastructure

A small MVP may operate with relatively modest infrastructure costs.

A high-traffic marketplace can spend thousands or tens of thousands of dollars per month on infrastructure and third-party services.

Infrastructure should scale with actual demand rather than projected demand alone.

Third-Party API Costs

Marketplace apps often rely on external services.

Examples include:

  • Payment gateways
  • Maps
  • SMS
  • Email
  • Push notifications
  • Identity verification
  • Shipping
  • Tax calculation
  • Analytics
  • Customer support
  • Search
  • AI

Each integration can create two separate expenses:

  1. Development and integration cost
  2. Recurring provider usage cost

Businesses should include both in their budget.

Marketplace App Security Costs

Security is particularly important because marketplaces handle:

  • Personal information
  • Seller information
  • Payment data
  • Business data
  • Order data
  • Communication data

Security work may include:

  • Secure authentication
  • Encryption
  • Access controls
  • API security
  • Rate limiting
  • Fraud prevention
  • Secure payment integration
  • Audit logs
  • Vulnerability testing
  • Backup strategy

Security testing may cost:

$3,000 to $20,000+

Enterprise requirements can be considerably higher.

Fraud Prevention

Marketplaces can be targeted by:

  • Fake sellers
  • Fake customers
  • Payment fraud
  • Account takeover
  • Fake reviews
  • Refund abuse
  • Coupon abuse
  • Chargebacks

Fraud prevention can involve:

  • Seller verification
  • Device monitoring
  • Transaction monitoring
  • Risk scoring
  • Manual review
  • Suspicious behavior detection
  • Payment provider fraud tools

The appropriate solution depends on transaction volume and business risk.

Marketplace Compliance Costs

Compliance requirements depend on:

  • Country
  • Marketplace category
  • Payment model
  • User data
  • Industry
  • Business structure

A marketplace may need to consider:

  • Privacy requirements
  • Consumer protection
  • Tax requirements
  • Payment regulations
  • Seller verification
  • Data retention
  • Terms and policies

Legal and compliance costs are separate from software development.

A marketplace should obtain appropriate legal advice for the jurisdictions in which it operates.

Cost of Testing a Marketplace App

Testing should cover more than whether individual buttons work.

Marketplace QA can include:

Functional Testing

Ensures features work correctly.

Payment Testing

Checks:

  • Successful payments
  • Failed payments
  • Refunds
  • Partial refunds
  • Duplicate transactions

Seller Testing

Checks:

  • Listing creation
  • Inventory
  • Orders
  • Payouts

Customer Testing

Checks:

  • Search
  • Cart
  • Checkout
  • Orders
  • Reviews

Performance Testing

Tests the application under expected loads.

Security Testing

Looks for vulnerabilities.

Device Testing

Checks multiple devices and operating systems.

Testing can cost approximately:

$4,000 to $20,000+

Cost of Maintaining a Marketplace App

Development is only the beginning.

After launch, businesses need ongoing maintenance.

Typical maintenance includes:

  • Bug fixes
  • Security updates
  • OS compatibility
  • Server maintenance
  • Database optimization
  • API updates
  • Feature improvements
  • Performance monitoring
  • App store updates

A common planning approach is to budget approximately 15% to 25% of the initial development cost per year for maintenance and improvements, although actual spending can vary considerably.

For a marketplace costing $100,000 to build, this could mean planning for approximately $15,000 to $25,000 per year.

This is a planning estimate rather than a mandatory industry fee.

Hidden Costs of Building a Marketplace App

Many businesses focus only on development.

That can produce an unrealistic budget.

Other costs may include:

  • Domain
  • Hosting
  • Cloud storage
  • Payment processing
  • SMS
  • Email
  • Maps
  • Identity verification
  • Customer support
  • Analytics
  • App store accounts
  • Legal services
  • Privacy policies
  • Security audits
  • Marketing
  • Seller acquisition
  • Customer acquisition
  • Content creation
  • Photography
  • Product onboarding

The technology budget is only one part of marketplace economics.

Marketplace Development Team

A marketplace typically requires several roles.

A small team may include:

  • Product manager
  • UI/UX designer
  • Frontend developer
  • Backend developer
  • Mobile developer
  • QA engineer
  • DevOps engineer

Not every person needs to work full-time throughout the project.

For example, a DevOps specialist may work heavily during infrastructure setup and deployment rather than throughout the entire design phase.

Hiring Freelancers for Marketplace Development

Freelancers can be suitable for smaller marketplace projects.

Advantages include:

  • Lower initial cost
  • Flexible staffing
  • Direct communication
  • Easier scaling for specific tasks

Challenges include:

  • Coordination
  • Availability
  • Project management
  • Code consistency
  • Long-term maintenance

A marketplace with multiple complex integrations may require several specialists.

Managing those specialists can become difficult without technical leadership.

Hiring a Development Agency

A development agency can provide a complete team.

Potential benefits include:

  • Product management
  • UI/UX
  • Development
  • QA
  • DevOps
  • Project management
  • Maintenance

The initial cost may be higher than hiring a single freelancer.

However, the agency approach can simplify project coordination.

Businesses should evaluate agencies based on relevant marketplace experience rather than simply selecting the lowest quotation.

Building an In-House Marketplace Team

An in-house team provides maximum control.

However, it can involve:

  • Salaries
  • Recruitment
  • Benefits
  • Equipment
  • Management
  • Office or remote infrastructure
  • Training
  • Employee retention

For a startup, hiring an entire engineering organization before validating the marketplace may create unnecessary fixed costs.

Freelancer vs Agency vs In-House

Approach Initial Cost Control Management Requirement
Freelancer Lower High High
Agency Medium to High Medium Lower
In-House High Very High Medium to High

The appropriate model depends on budget, technical leadership, product complexity, and long-term plans.

How to Build a Marketplace MVP

An MVP should focus on the smallest product that can test the marketplace model.

For a product marketplace, an MVP might include:

Customer

  • Registration
  • Search
  • Categories
  • Product details
  • Cart
  • Checkout
  • Payment
  • Orders
  • Reviews

Seller

  • Registration
  • Verification
  • Product listing
  • Inventory
  • Orders
  • Earnings

Admin

  • User management
  • Seller management
  • Product management
  • Orders
  • Payments
  • Commissions
  • Basic analytics

This can be enough to test whether the marketplace actually works.

What Not to Build in the First Version

Startups often want to launch with:

  • AI recommendations
  • Loyalty programs
  • Advanced advertising
  • Multiple subscription plans
  • Complex seller analytics
  • Social feeds
  • Video commerce
  • Live streaming
  • Advanced personalization
  • Multi-country support

These features may eventually be valuable.

They are not always necessary for proving the core marketplace model.

A lean MVP can reduce both cost and time to market.

Example Marketplace MVP Budget

Suppose a startup wants to build a marketplace connecting independent sellers with customers.

The initial budget might look like:

Area Estimated Budget
Product discovery $2,000
UI/UX design $7,000
Customer app $12,000
Seller dashboard $10,000
Backend $18,000
Admin panel $7,000
Payment integration $4,000
Testing $6,000
DevOps $3,000
Launch support $3,000
Estimated Total $72,000

This is an example budget, not a universal quote.

A simpler product could cost significantly less.

A more complex marketplace could cost substantially more.

Example: Service Marketplace Cost

Consider a marketplace connecting customers with local professionals.

The platform may include:

  • Customer app
  • Provider dashboard
  • Provider profiles
  • Service listings
  • Search
  • Location
  • Availability
  • Booking
  • Payments
  • Messaging
  • Reviews
  • Notifications
  • Admin dashboard

An MVP could potentially fall around:

$30,000 to $60,000

A mature platform with advanced scheduling, payments, maps, subscriptions, provider analytics, and automation could move toward:

$80,000 to $200,000+

Example: Rental Marketplace Cost

A rental marketplace has additional complexity.

It may require:

  • Item listings
  • Availability
  • Calendar
  • Booking
  • Deposits
  • Payments
  • Pickup
  • Returns
  • Cancellation
  • Damage reporting
  • Messaging
  • Reviews

A basic rental marketplace may cost:

$30,000 to $70,000

An advanced platform may exceed:

$100,000 to $250,000

Example: B2B Marketplace Cost

A B2B marketplace can require additional features such as:

  • Business accounts
  • Bulk ordering
  • Negotiated pricing
  • Purchase orders
  • Credit limits
  • Invoices
  • Tax management
  • Sales representatives
  • Approval workflows
  • Bulk product imports

A B2B marketplace MVP may cost:

$40,000 to $80,000

A sophisticated enterprise B2B marketplace can exceed:

$150,000 to $500,000

Example: Real Estate Marketplace Cost

A property marketplace may need:

  • Property listings
  • Agent profiles
  • Search
  • Map search
  • Filters
  • Photos
  • Videos
  • Virtual tours
  • Saved searches
  • Favorites
  • Lead forms
  • Messaging
  • Appointment booking

A basic real estate marketplace could cost:

$30,000 to $70,000

A more advanced platform could cost:

$100,000 to $250,000+

Example: Freelancer Marketplace Cost

A freelancer marketplace can be significantly more complicated.

It may need:

  • Freelancer profiles
  • Client profiles
  • Job postings
  • Proposals
  • Messaging
  • Contracts
  • Milestones
  • Payments
  • Disputes
  • Reviews
  • Notifications
  • Search
  • Freelancer verification

Adding time tracking, escrow, automated contracts, and sophisticated matching can increase the cost substantially.

An MVP may cost:

$40,000 to $80,000

A mature freelancer platform may require:

$150,000 to $500,000+

Marketplace Business Models

Development cost also depends on how the marketplace makes money.

Commission Model

The platform takes a percentage of each transaction.

Example:

A seller makes a $100 sale.

The marketplace charges a 10% commission.

Marketplace revenue:

$10

Seller share:

$90 before applicable fees and adjustments.

The software must calculate this automatically.

Subscription Model

Sellers pay a recurring fee.

For example:

  • Free
  • Professional
  • Business

Subscription management requires recurring billing and account status logic.

Listing Fee Model

Sellers pay to publish listings.

This is common in some classified marketplaces.

The system needs to manage:

  • Listing payments
  • Listing duration
  • Expiration
  • Renewals
  • Featured placement

Advertising Model

Sellers pay to promote their listings.

This requires advertising infrastructure.

At scale, advertising can become a substantial software product by itself.

Hybrid Marketplace Model

Many marketplaces combine:

  • Commission
  • Seller subscriptions
  • Listing fees
  • Advertising
  • Premium services

A hybrid model increases business flexibility but can also increase software complexity.

Marketplace Unit Economics

Before spending heavily on development, founders should understand marketplace unit economics.

Important metrics include:

Gross Merchandise Value

GMV represents the total value of transactions processed through the marketplace.

If 1,000 orders have an average order value of $50:

GMV = $50,000.

The marketplace does not necessarily keep all $50,000.

Take Rate

The take rate represents the percentage of GMV retained by the marketplace through commissions and other transaction revenue.

For example:

GMV = $100,000

Marketplace revenue = $10,000

Take rate = 10%

This is an important marketplace metric.

Customer Acquisition Cost

CAC measures the cost of acquiring customers.

If a marketplace spends $5,000 acquiring 100 customers:

CAC = $50 per customer.

A marketplace should compare acquisition cost with customer lifetime value.

Customer Lifetime Value

LTV estimates the economic value generated by a customer over their relationship with the marketplace.

A customer who purchases repeatedly can be significantly more valuable than a one-time buyer.

Seller Acquisition Cost

Marketplaces have another challenge.

They need to acquire sellers.

Seller acquisition may involve:

  • Sales teams
  • Outreach
  • Advertising
  • Partnerships
  • Incentives
  • Onboarding support

A marketplace therefore has both demand-side and supply-side acquisition costs.

The Marketplace Chicken and Egg Problem

A marketplace needs buyers to attract sellers.

It also needs sellers to attract buyers.

This creates a common marketplace challenge.

A technically excellent application can still fail if the platform does not achieve enough liquidity.

Liquidity means users can actually find what they need and complete transactions.

This is why marketplace strategy is just as important as software development.

How to Reduce Marketplace App Development Cost

There are several practical ways to control costs.

Start With One Platform

Instead of launching:

  • iOS
  • Android
  • Web
  • Seller app
  • Admin app

consider launching a smaller combination.

For example:

  • Cross-platform customer app
  • Seller web dashboard
  • Admin web dashboard

Use Third-Party Services

Building every system from scratch is rarely necessary.

Businesses can use established providers for:

  • Payments
  • Maps
  • SMS
  • Email
  • Analytics
  • Authentication
  • Cloud infrastructure

This reduces development time.

The business still needs to evaluate vendor dependency, pricing, data handling, and scalability.

Use a Cross-Platform Framework

For many startup marketplaces, cross-platform development can reduce duplicated work.

However, the technology should still match the product requirements.

Build a Modular Backend

The backend should be structured so that features can be added later.

For example:

Version 1:

  • Users
  • Sellers
  • Listings
  • Orders
  • Payments

Version 2:

  • Subscriptions
  • Promotions
  • Analytics

Version 3:

  • Recommendations
  • Advertising
  • AI

This approach avoids rebuilding the entire application.

Prioritize Features Using Business Impact

Every feature should answer a business question.

Instead of asking:

“Can we add this feature?”

Ask:

“Will this feature help us acquire users, increase transactions, improve retention, reduce costs, or increase revenue?”

This helps prevent unnecessary development.

Common Marketplace App Development Mistakes

Building Too Many Features

A large feature list can delay launch.

The marketplace may need months of development before real users provide feedback.

Ignoring Seller Experience

Founders sometimes focus entirely on customers.

But sellers are equally important.

A seller who finds onboarding difficult may never list products.

Underestimating Payments

Marketplace payments are more complicated than simple checkout.

Commission, refunds, payouts, taxes, disputes, and settlement rules should be considered early.

Ignoring Search

If customers cannot find the right product or service quickly, marketplace conversion can suffer.

Search and filtering should be treated as core functionality.

Weak Admin Tools

The marketplace team needs efficient administration.

Manual processes can become expensive as the number of sellers grows.

Not Planning for Disputes

Marketplaces inevitably encounter:

  • Refund requests
  • Seller complaints
  • Customer complaints
  • Damaged goods
  • Late delivery
  • Cancellations
  • Fraud

Dispute workflows should be considered during product planning.

How to Choose the Right Marketplace Technology Stack

A typical technology stack may include:

Mobile

  • Flutter
  • React Native
  • Swift
  • Kotlin

Frontend

  • React
  • Next.js
  • Vue

Backend

  • Node.js
  • Python
  • Java
  • PHP
  • .NET

Database

  • PostgreSQL
  • MySQL
  • MongoDB
  • Redis for specific caching or real-time workloads

Cloud

  • AWS
  • Google Cloud
  • Microsoft Azure

The best stack depends on:

  • Team expertise
  • Product requirements
  • Scale
  • Integrations
  • Security
  • Budget
  • Long-term maintenance

There is no universally perfect marketplace technology stack.

Monolithic vs Microservices Architecture

A startup marketplace does not necessarily need microservices from day one.

A well-designed modular monolith can be easier and cheaper to build initially.

As the platform grows, services can be separated where necessary.

Microservices can provide benefits at scale but introduce:

  • More infrastructure
  • More deployment complexity
  • More monitoring
  • More networking
  • More operational overhead

Architecture should match actual business requirements.

Scalability Considerations

A marketplace should be designed with growth in mind.

Potential growth areas include:

  • Users
  • Sellers
  • Listings
  • Orders
  • Messages
  • Images
  • Transactions

Important scalability mechanisms can include:

  • Caching
  • Database indexing
  • CDN
  • Load balancing
  • Queue systems
  • Horizontal scaling
  • Search indexing
  • Image optimization

Scaling everything prematurely can waste money.

The goal is to create a foundation that can evolve as demand becomes real.

Marketplace App Performance

Performance affects user experience.

Important areas include:

  • Application startup
  • Search response
  • Product loading
  • Image loading
  • Checkout speed
  • API response time

Large product images can create performance problems.

Image optimization and content delivery can significantly improve marketplace experiences.

Marketplace App Security Best Practices

A marketplace should consider:

  • Strong authentication
  • Secure password storage
  • Token security
  • API authorization
  • Input validation
  • Encryption
  • Secure payment handling
  • Rate limiting
  • Monitoring
  • Logging
  • Regular dependency updates

Security should be built into the architecture rather than added at the end.

Marketplace App Launch Strategy

Launching the software is not the same as launching the marketplace.

Before launch, businesses should prepare:

Supply

Recruit enough sellers or service providers.

Demand

Develop a strategy for acquiring customers.

Content

Ensure listings are high quality.

Support

Prepare customer and seller support.

Operations

Define refund, cancellation, verification, and dispute processes.

A marketplace can have excellent software but poor liquidity.

Geographic Launch Strategy

Launching in one focused geographic market can simplify:

  • Logistics
  • Seller acquisition
  • Customer acquisition
  • Support
  • Payments
  • Compliance
  • Operations

After proving the model, the platform can expand into additional markets.

Marketplace App Cost Optimization Strategy

A practical approach is to divide the product into three stages.

Stage 1: Validation

Build:

  • Registration
  • Seller onboarding
  • Listings
  • Search
  • Checkout
  • Payments
  • Orders
  • Basic admin

Goal:

Validate marketplace demand.

Stage 2: Optimization

Add:

  • Reviews
  • Messaging
  • Better analytics
  • Promotions
  • Seller tools
  • Improved search
  • Customer retention features

Goal:

Improve conversion and retention.

Stage 3: Scale

Add:

  • Advanced analytics
  • Automation
  • AI
  • Advertising
  • Internationalization
  • Advanced logistics
  • Enterprise integrations

Goal:

Improve efficiency and support larger transaction volume.

Three-Year Marketplace Technology Budget

The initial development cost is not the complete financial picture.

Consider a marketplace that costs $75,000 to develop.

A three-year technology budget might include:

Initial Development

$75,000

Annual Maintenance

Approximately $11,000 to $19,000 per year

Cloud and Third-Party Services

Variable

Security

Variable

Product Improvements

Variable

Support

Variable

The actual three-year cost could therefore be considerably higher than the initial development quotation.

Businesses should calculate total cost of ownership rather than comparing only initial development prices.

Total Cost of Ownership

Total cost of ownership can include:

Development + infrastructure + maintenance + third-party services + security + support + future features

For example:

Initial development:

$80,000

Three years of maintenance:

$45,000

Infrastructure and services:

$30,000

Additional features:

$50,000

Estimated three-year technology spending:

$205,000

This is only an example.

Actual costs depend heavily on usage and product evolution.

Marketplace App Cost Calculator Framework

A simple planning formula can be:

Total Development Cost = Design + Frontend + Backend + Admin + Integrations + QA + DevOps + Project Management

Then add:

Total Ownership Cost = Development + Maintenance + Infrastructure + Third-Party Services + Future Development

This framework provides a better estimate than simply multiplying a developer’s hourly rate by an arbitrary number of hours.

Questions to Ask Before Getting a Marketplace App Quote

Before approaching development companies, prepare answers to these questions:

  1. What type of marketplace are you building?
  2. Who are the buyers?
  3. Who are the sellers?
  4. What will sellers offer?
  5. How will the marketplace make money?
  6. Will sellers use a mobile app or web dashboard?
  7. Will customers use iOS, Android, web, or all three?
  8. What payment methods are required?
  9. How will sellers receive payouts?
  10. Is seller verification required?
  11. Will the platform support multiple currencies?
  12. Will it support multiple countries?
  13. Is location functionality required?
  14. Is messaging required?
  15. Is booking required?
  16. Will logistics be integrated?
  17. What happens when an order is cancelled?
  18. How will refunds work?
  19. What happens during a dispute?
  20. What analytics are required?

The clearer these answers are, the more accurate the development estimate will be.

How to Get an Accurate Marketplace App Development Estimate

A reliable estimate should be based on a detailed scope.

A development company should ideally provide:

  • Feature list
  • User flows
  • Platform requirements
  • Technology recommendations
  • UI/UX scope
  • Backend scope
  • Third-party integrations
  • Testing scope
  • Deployment scope
  • Maintenance terms
  • Estimated timeline
  • Team composition
  • Payment milestones

Avoid comparing proposals only by the final number.

A $30,000 quote and a $100,000 quote may describe completely different products.

Fixed Price vs Time and Materials

There are two common development pricing approaches.

Fixed Price

The client and development company agree on a defined scope and price.

Advantages:

  • Predictable budget
  • Clear scope
  • Easier financial planning

Limitations:

  • Changes can require additional contracts
  • Less flexibility
  • Detailed requirements are necessary

Time and Materials

The client pays according to development time.

Advantages:

  • Flexible scope
  • Easier iteration
  • Suitable for evolving products

Limitations:

  • Final cost is less predictable
  • Requires strong project management

For marketplace startups where requirements are likely to change after user feedback, flexibility can be valuable.

How Much Does It Cost to Build a Marketplace App Like Etsy?

  • Seller profiles
  • Product listings
  • Categories
  • Search
  • Filters
  • Cart
  • Payments
  • Reviews
  • Seller management
  • Orders
  • Messaging
  • Commissions

A simplified version could cost approximately:

$40,000 to $100,000

A larger version with advanced personalization, advertising, seller analytics, international support, and extensive integrations can exceed:

$200,000

The actual budget depends on which functionality is replicated and how much customization is required.

How Much Does It Cost to Build a Marketplace Like Airbnb?

A rental marketplace similar in functionality to Airbnb requires significantly more than listing pages.

It may require:

  • Property listings
  • Host profiles
  • Search
  • Map integration
  • Availability
  • Calendar
  • Booking
  • Payments
  • Messaging
  • Reviews
  • Cancellation rules
  • Notifications

An advanced global platform can require:

$250,000 to $500,000+

The most complex components include availability, booking, payments, messaging, location, and host management.

How Much Does It Cost to Build a Marketplace Like Uber?

A transportation marketplace is substantially more complex.

It can involve:

  • Customer application
  • Driver application
  • Real-time location
  • Matching
  • Maps
  • Routing
  • Fare calculation
  • Payments
  • Driver payouts
  • Trip tracking
  • Ratings
  • Notifications

$40,000 to $100,000

An advanced platform with complex payments, contracts, time tracking, dispute systems, and recommendation technology can exceed:

$200,000

How Much Does It Cost to Build a Marketplace Like Amazon?

A marketplace with the breadth of Amazon is an enterprise software ecosystem rather than a typical mobile app.

It can involve:

  • Millions of products
  • Thousands of sellers
  • Search infrastructure
  • Payments
  • Logistics
  • Warehousing
  • Recommendations
  • Advertising
  • Reviews
  • Customer support
  • Seller analytics
  • Fraud detection
  • Multiple regions

Building a platform at this level from scratch requires a very substantial engineering organization and infrastructure budget.

For most startups, the correct strategy is not to replicate the entire system.

Instead, build a focused marketplace around one category and expand based on demand.

Marketplace App Development Cost: MVP vs Full Product

Feature MVP Full Product
Registration Yes Yes
Seller onboarding Basic Advanced
Listings Yes Advanced
Search Basic Advanced
Payments Yes Multiple methods
Orders Basic Advanced
Reviews Basic Advanced moderation
Messaging Optional Usually included
Analytics Basic Advanced
Promotions Limited Advanced
Subscriptions Optional Possible
Advertising No Possible
AI Usually no Optional
Internationalization Usually no Possible

The MVP approach allows founders to validate demand before making larger investments.

When Should You Build Advanced Features?

Advanced features should generally be added when there is evidence that they solve a real problem.

For example:

If sellers are struggling to manage large catalogs, bulk upload tools may become important.

If customers cannot find relevant products, better search may be justified.

If sellers want more visibility, sponsored listings may become a monetization opportunity.

If customers struggle to discover products, recommendations may become useful.

This creates a product roadmap based on actual marketplace behavior.

Marketplace App ROI Considerations

The return on investment depends on more than application revenue.

A marketplace can generate value through:

  • Transaction commissions
  • Seller subscriptions
  • Listing fees
  • Advertising
  • Premium services
  • Payment-related revenue
  • Data insights
  • Partnerships

For example, suppose a marketplace processes:

$1 million GMV per year

At a 10% take rate:

Marketplace transaction revenue = $100,000

But the marketplace may also have:

  • Payment costs
  • Hosting costs
  • Customer support
  • Seller acquisition
  • Customer acquisition
  • Refunds
  • Employee costs

Therefore, GMV should not be confused with profit.

Marketplace Profitability

A marketplace can become profitable when:

Marketplace Revenue > Operating Costs

Operating costs can include:

  • Technology
  • Employees
  • Marketing
  • Customer support
  • Payment fees
  • Seller incentives
  • Refunds
  • Infrastructure
  • Legal and compliance

The marketplace needs sufficient transaction volume and healthy unit economics.

Why Marketplace Development Cost Should Not Be the Only Decision

The cheapest application is not necessarily the least expensive product over time.

For example, suppose:

Option A costs $30,000.

Option B costs $60,000.

If Option A requires a complete rewrite after reaching initial traction, its total cost may become higher.

The better approach is to evaluate:

  • Architecture
  • Scalability
  • Code quality
  • Security
  • Testing
  • Maintainability
  • Team expertise
  • Product fit

The objective should be to optimize total product economics rather than minimize the first invoice.

Recommended Marketplace Development Roadmap

A practical roadmap can look like this.

Phase 1: Research

Define:

  • Market
  • Customers
  • Sellers
  • Competitors
  • Revenue model
  • Core problem

Phase 2: MVP Planning

Select only essential features.

Phase 3: UX

Create:

  • User flows
  • Wireframes

What is the most expensive part of a marketplace app?

Backend engineering, complex transaction workflows, seller management, payment and payout systems, integrations, and advanced infrastructure can represent significant portions of the budget.

Can I build a marketplace app for $20,000?

A focused MVP may be possible within a $20,000 budget if the scope is tightly controlled. A smaller number of platforms, limited integrations, reusable components, and essential features can help keep development within that range.

Can I build a marketplace app without a mobile application?

Yes. A responsive web marketplace or Progressive Web App can be used initially. This can reduce the initial development budget and allow the business to validate demand before investing in native mobile applications.

Should I build iOS and Android simultaneously?

It depends on your target customers. Cross-platform development can allow a startup to support both platforms while sharing significant portions of the codebase.

How much does a seller dashboard cost?

A basic seller dashboard may cost approximately $4,000 to $10,000. Advanced dashboards with analytics, bulk uploads, promotions, inventory management, and financial reporting can cost significantly more.

How much does a marketplace admin panel cost?

A basic admin panel can cost approximately $4,000 to $10,000. Advanced administrative systems with detailed reporting, roles, moderation, finance tools, and seller management can cost $20,000 or more.

How much does marketplace maintenance cost?

A common planning range is approximately 15% to 25% of initial development cost per year, although actual maintenance costs depend on application complexity, infrastructure, integrations, and the pace of product development.

Do marketplace apps require payment integration?

Most transaction-based marketplaces do. However, the exact payment architecture depends on the marketplace model and how customers pay sellers.

How does a marketplace make money?

Common revenue models include commissions, subscriptions, listing fees, advertising, transaction fees, and premium seller services.

What technology is best for a marketplace app?

There is no single best technology for every marketplace. Flutter, React Native, Swift, Kotlin, React, Next.js, Node.js, Python, Java, .NET, PostgreSQL, and other technologies can all be appropriate depending on requirements.

Should I build a custom marketplace or use an existing platform?

An existing marketplace platform can reduce initial development cost and time. Custom development provides greater control over workflows, integrations, scalability, and differentiation. The right option depends on the business model and long-term requirements.

How much does an AI-powered marketplace cost?

An AI-powered marketplace can cost substantially more than a conventional marketplace, depending on the AI functionality. Simple API-based features may add a few thousand dollars, while custom recommendation, search, forecasting, or machine learning systems can require much larger investments.

Is marketplace development more expensive than ecommerce development?

Usually, yes, because a marketplace has to support multiple sellers and additional workflows such as seller onboarding, commissions, payouts, seller dashboards, moderation, disputes, and marketplace administration.

Conclusion

So, how much does it cost to build a marketplace app?

A realistic planning range is $15,000 to $500,000 or more, depending on the size and complexity of the platform.

A focused marketplace MVP can potentially be built for $15,000 to $40,000. A standard marketplace may require $40,000 to $100,000, while an advanced platform can reach $100,000 to $250,000 or more. Enterprise marketplaces with sophisticated infrastructure, multiple integrations, international operations, advanced security, and high transaction volumes can exceed $250,000 to $500,000.

For businesses in India, a basic marketplace MVP may fall around ₹12 lakh to ₹35 lakh, while larger applications can require several crores.

However, development cost should not be viewed in isolation.

A successful marketplace needs more than a mobile application. It needs a reliable transaction system, strong seller experience, efficient customer discovery, secure payments, useful administration tools, effective support, and a sustainable business model.

The most practical approach for many startups is to begin with a focused MVP.

Build the essential customer, seller, payment, transaction, and administrative workflows first. Launch in a narrow market. Measure actual customer and seller behavior. Then invest in advanced search, automation, analytics, AI, advertising, subscriptions, logistics, and international functionality as the marketplace gains traction.

The objective is not to build the biggest marketplace on day one.

The objective is to build enough technology to prove the marketplace model, create liquidity, generate transactions, and establish a foundation that can scale with the business.
