Building a B2B ecommerce portal is significantly more complex than building a conventional online store.
A standard ecommerce website is generally designed around an individual shopper who browses products, adds items to a cart, pays online, and receives an order confirmation.
A B2B ecommerce portal has to support an entirely different purchasing environment.
A single customer account may represent an entire company. Multiple employees may use the same account with different permissions. Prices may differ from one customer to another. Some buyers may require approval before placing an order. Others may purchase against negotiated contracts, credit limits, purchase orders, or agreed payment terms.
The portal may also need to connect with ERP, CRM, accounting, inventory, warehouse, shipping, tax, payment, and customer-support systems.
That is why asking only, “How much does an ecommerce website cost?” is not enough when planning a B2B ecommerce project.
The more useful question is:
How much does it cost to build the B2B commerce system your business actually needs?
In 2026, a practical development budget for a B2B ecommerce portal in India can range from approximately ₹8 lakh to ₹30 lakh or more, depending on functionality, platform, integrations, design requirements, automation, and scalability.
A relatively straightforward B2B portal can fall toward the lower end. A highly customized enterprise B2B commerce platform can move substantially beyond ₹30 lakh.
Published Indian ecommerce development estimates also place B2B ecommerce platforms in the broad ₹8 lakh to ₹30 lakh+ range, although actual project quotations vary according to scope and implementation complexity.
This guide explains the factors behind that cost, what features a B2B portal needs, where development budgets are spent, how platform selection affects the investment, and how businesses can structure a realistic B2B ecommerce budget in 2026.
For businesses planning development in India in 2026, the following ranges can be used as an initial budgeting framework.
| B2B Ecommerce Portal Type | Approximate Development Cost |
| Basic B2B ecommerce portal | ₹8 lakh to ₹12 lakh |
| Small wholesale portal | ₹8 lakh to ₹15 lakh |
| Standard B2B ecommerce platform | ₹12 lakh to ₹20 lakh |
| Custom B2B ecommerce portal | ₹15 lakh to ₹30 lakh |
| Advanced B2B commerce platform | ₹20 lakh to ₹40 lakh+ |
| B2B portal with ERP integration | ₹18 lakh to ₹35 lakh+ |
| B2B portal with complex pricing | ₹20 lakh to ₹40 lakh+ |
| Enterprise B2B ecommerce platform | ₹30 lakh to ₹60 lakh+ |
| Multi-country B2B ecommerce platform | ₹40 lakh to ₹80 lakh+ |
| Highly customized B2B commerce ecosystem | ₹50 lakh to ₹1 crore+ |
These are planning ranges, not fixed market prices.
The actual cost depends heavily on whether the business uses an existing B2B ecommerce platform, customizes an established commerce platform, or builds a largely custom commerce application.
The difference can be substantial.
A company selling 200 SKUs to a few hundred wholesale buyers does not necessarily need the same architecture as a manufacturer serving thousands of business customers across multiple countries.
A B2B ecommerce portal is an online commerce system designed specifically for transactions between businesses.
Instead of selling directly to individual consumers, the business uses the platform to sell products or services to other companies.
Typical B2B ecommerce customers include:
The portal can allow these organizations to browse products, view account-specific prices, request quotations, place bulk orders, manage purchase orders, review invoices, track shipments, and communicate with the seller.
Modern B2B platforms can also support multiple buyers under a single company account, different purchasing permissions, personalized catalogs, negotiated prices, payment terms, and automated workflows.
This makes B2B ecommerce fundamentally different from a typical D2C store.
The difference becomes clearer when comparing the two models.
| Feature | B2C Ecommerce | B2B Ecommerce |
| Primary customer | Individual | Business |
| Account structure | Individual customer | Company + multiple buyers |
| Pricing | Usually public | Often customer-specific |
| Order size | Small | Medium to very large |
| Payment | Card, UPI, wallets, COD | Credit terms, PO, bank transfer, online payment |
| Approval workflows | Rare | Common |
| Negotiated pricing | Rare | Common |
| Bulk ordering | Optional | Often essential |
| Quote management | Limited | Frequently required |
| ERP integration | Useful | Often critical |
| CRM integration | Useful | Often important |
| Sales representative access | Optional | Often required |
| Credit limits | Rare | Common |
| Reordering | Useful | Extremely important |
| Customer-specific catalogs | Rare | Common |
| Multiple shipping locations | Sometimes | Common |
| Buyer permissions | Basic | Advanced |
| Tax handling | Standard | Customer-specific in many cases |
| Purchase orders | Rare | Common |
| Product configuration | Sometimes | Frequently required in complex industries |
This additional business logic is one of the main reasons B2B ecommerce development costs more.
The visual storefront is only one part of a B2B ecommerce system.
The expensive part is often the business logic behind it.
Consider a simple scenario.
A retail customer sees:
Product A: ₹1,000
A B2B buyer might see:
Product A: ₹850
But another customer could see:
Product A: ₹790
A third customer may receive:
Product A: ₹760 above 500 units
Another buyer might have:
Product A: ₹740 under a negotiated annual contract
The portal therefore needs to determine:
That is where B2B ecommerce development becomes a complex software project rather than simply a website project.
A B2B ecommerce budget can be divided into several major components.
Before development begins, the team needs to understand how the company currently sells to business customers.
This stage can include:
Estimated cost:
₹50,000 to ₹2 lakh
For smaller projects, discovery may be included in the development quotation.
For enterprise implementations, discovery can become a significant standalone project.
B2B portals need a different user experience from consumer ecommerce websites.
Business buyers frequently know what they want.
They may search directly by:
They may also reorder products they purchased previously.
Therefore, the design should prioritize productivity rather than simply visual presentation.
Important interfaces may include:
Estimated UI/UX cost:
₹1 lakh to ₹4 lakh+
Enterprise UX projects can cost considerably more.
A B2C ecommerce store normally treats the customer as one person.
B2B ecommerce often treats the customer as a company.
For example:
ABC Manufacturing Pvt. Ltd.
could have:
Each person may have different permissions.
The purchasing executive may create an order.
The manager may approve it.
The finance manager may manage invoices.
The administrator may add or remove users.
The company owner may have full access.
This requires a role-based account architecture.
Estimated development cost:
₹1 lakh to ₹3 lakh
The cost rises when the business requires highly customized organizational structures.
Customer-specific pricing is one of the most important B2B ecommerce capabilities.
Different customers may have different prices based on:
For example:
| Customer Type | Product Price |
| Standard Buyer | ₹1,000 |
| Wholesale Buyer | ₹900 |
| Distributor | ₹820 |
| Premium Distributor | ₹780 |
| Contract Customer | ₹750 |
The portal must determine which price applies automatically.
Platforms such as Adobe Commerce support shared catalogs and custom pricing for different companies, while Salesforce B2B Commerce supports price books and buyer-specific pricing structures.
Estimated cost for customized pricing:
₹1.5 lakh to ₹5 lakh+
The product catalog is another major component.
A B2B catalog can be much more complicated than a standard ecommerce catalog.
Products may include:
A manufacturing business may also need:
Estimated catalog development:
₹1 lakh to ₹4 lakh+
Business customers usually do not want to browse 30 pages of products to place a repeat order.
They may already know the SKUs they need.
A quick-order interface can allow buyers to enter:
SKU | Quantity
For example:
| SKU | Quantity |
| ABC-102 | 100 |
| XYZ-221 | 250 |
| DEF-009 | 50 |
The system can then add those products directly to the cart.
Adobe Commerce’s B2B functionality includes Quick Order, allowing buyers to place orders using SKU or product name.
Estimated cost:
₹50,000 to ₹2 lakh
Many B2B businesses do not sell one unit at a time.
They may require:
The portal must enforce these rules.
For example:
A product might have:
Minimum order quantity: 100
The customer should not be allowed to order 25 units.
Alternatively, the business may allow:
100, 200, 300, 400…
but not:
125 or 175
These rules need to be implemented at the commerce-engine level.
Quote management is another common B2B requirement.
Instead of immediately paying the listed price, a customer can request a quote.
The workflow might look like:
Customer adds products
↓
Customer requests quote
↓
Sales team receives request
↓
Sales representative adjusts pricing
↓
Customer receives quotation
↓
Customer accepts
↓
Order is created
↓
Payment or credit processing
Modern B2B platforms support quote workflows for this reason. Adobe Commerce provides B2B Quotes, while Salesforce documents Request for Quote capabilities for B2B Commerce.
Estimated development cost:
₹1 lakh to ₹3 lakh+
Approval workflows are particularly important for larger companies.
Imagine an employee places an order worth ₹5 lakh.
The business may require approval from a manager before the order can be submitted.
A possible workflow:
Employee creates order
↓
Order exceeds ₹2 lakh
↓
Manager approval required
↓
Manager approves
↓
Finance approval
↓
Order submitted
The rules can vary by:
Estimated cost:
₹1 lakh to ₹4 lakh+
Many B2B customers prefer purchase orders instead of immediate online payment.
The portal may allow buyers to:
This functionality becomes particularly important for enterprise procurement.
Estimated cost:
₹75,000 to ₹3 lakh+
Credit-based purchasing can significantly increase the complexity of a B2B portal.
For example:
Customer credit limit: ₹10 lakh
Current outstanding: ₹6 lakh
Available credit: ₹4 lakh
If the customer tries to place a ₹5 lakh order, the system might:
Credit information may need to come directly from the ERP or accounting system.
Estimated development cost:
₹1 lakh to ₹4 lakh+
B2B businesses often use payment terms such as:
The system may need to determine which payment terms each customer can use.
One company may receive:
Net 30
while another receives:
Net 60
A new customer may be required to:
Pay online before shipment
This means payment logic becomes part of customer-account management.
ERP integration is often one of the biggest contributors to B2B ecommerce development cost.
Common ERP systems include:
The ecommerce portal may need to exchange:
For example:
ERP → Ecommerce
Product data
Inventory
Prices
Customer accounts
Credit limits
And:
Ecommerce → ERP
Orders
Customer registrations
Payments
Returns
Quote conversions
The integration may be real-time or scheduled.
Estimated cost:
₹2 lakh to ₹8 lakh+ per major integration
Complex enterprise integrations can cost significantly more.
A B2B ecommerce portal may also connect to a CRM.
Possible CRM systems include:
The integration can help sales teams understand:
Sales representatives can then work alongside ecommerce rather than operating separately.
Estimated cost:
₹1 lakh to ₹5 lakh+
Inventory becomes complicated when a business has multiple warehouses.
For example:
Warehouse A: Mumbai
Warehouse B: Delhi
Warehouse C: Ahmedabad
The portal may need to determine:
If inventory is already managed by an ERP, integration is often preferable to building a second inventory system.
B2B customers may have multiple delivery addresses.
A single company could have:
The portal may allow a buyer to select different shipping locations for different orders.
Advanced systems may even allow one order to be divided between multiple addresses.
Estimated cost:
₹1 lakh to ₹4 lakh+
Many B2B businesses still rely heavily on sales representatives.
Instead of replacing the sales team, ecommerce can make the sales team more efficient.
A sales representative might be able to:
This creates a hybrid model where customers can self-serve while sales representatives can intervene when necessary.
Estimated cost:
₹1 lakh to ₹5 lakh+
A good B2B customer dashboard can provide access to:
A more advanced dashboard can show:
Estimated cost:
₹1 lakh to ₹4 lakh+
B2B buyers often need much more powerful search than ordinary consumers.
They may search by:
Advanced filtering may be essential when the catalog contains thousands or millions of products.
Search technology can include:
Estimated cost:
₹75,000 to ₹4 lakh+
B2B recommendations can be based on:
For example:
A customer buying industrial printers may automatically see:
The value of recommendations is often higher in B2B because repeat purchasing is common.
Reordering should be considered a core B2B feature.
A customer should ideally be able to open:
Previous Orders
and click:
Reorder
The system can then recreate the cart.
More advanced systems can provide:
Buy Again
Frequently Ordered
Saved Lists
Requisition Lists
Recurring Orders
These features reduce the time required for repeat purchases.
A company may repeatedly purchase the same collection of products.
Instead of creating a cart from scratch every time, buyers can create lists such as:
Monthly Office Supplies
Factory Maintenance
Packaging Materials
Store Opening Kit
The buyer can add the list to the cart whenever needed.
Adobe Commerce B2B includes requisition-list functionality alongside company accounts, shared catalogs, and other B2B features.
Some B2B businesses sell products regularly.
Examples include:
The portal can support recurring purchasing.
For example:
500 units every month
or:
₹50,000 monthly replenishment
The implementation becomes more complex when customers need to modify recurring quantities or pause orders.
B2B customers often need detailed financial documentation.
The portal may provide:
The finance data may come from the ERP rather than the ecommerce platform.
B2B returns can be more complicated than consumer returns.
The portal may need to handle:
An advanced implementation can connect the entire workflow to the ERP.
The portal can send notifications for:
Channels can include:
Each additional communication channel can add development and recurring service costs.
The admin dashboard is the operational center of the B2B portal.
Administrators may need to manage:
The complexity of the admin panel can significantly affect development cost.
B2B businesses need more than basic ecommerce analytics.
Useful reports include:
Advanced analytics may be integrated with:
A B2B portal does not always require mobile applications.
However, apps can be useful when buyers and sales representatives frequently order from mobile devices.
A mobile app could allow:
Typical additional development budget:
₹5 lakh to ₹15 lakh+
Building separate native iOS and Android apps can cost more than using a cross-platform framework.
A useful way to budget the project is by complexity.
Approximate cost: ₹8 lakh to ₹12 lakh
Suitable for:
Possible features:
Approximate cost: ₹12 lakh to ₹20 lakh
Suitable for:
Typical features:
This is often the range where B2B ecommerce starts becoming a serious digital sales channel rather than simply an online catalog.
Approximate cost: ₹20 lakh to ₹40 lakh+
Suitable for:
Potential features:
Approximate cost: ₹30 lakh to ₹60 lakh+
Enterprise implementations may involve:
At this level, the project should be treated as a commerce technology ecosystem rather than a website.
A global B2B ecommerce portal can cost:
₹40 lakh to ₹80 lakh+
depending on scope.
Additional complexity can come from:
A headless B2B commerce implementation can typically start around:
₹20 lakh
and move toward:
₹50 lakh+
depending on the backend and integrations.
The frontend may use technologies such as:
while the commerce backend is separated through APIs.
Headless architecture becomes particularly useful when the business needs highly customized customer experiences, multiple frontend channels, or sophisticated integrations.
However, headless should not be selected simply because it is technically fashionable.
It introduces additional engineering responsibility.
The platform choice has a major effect on the overall budget.
Common options include:
Shopify provides native B2B capabilities that allow businesses to manage companies, catalogs, payment terms, self-service ordering, and other B2B functionality.
Shopify’s current documentation states that B2B can be used on supported plans and that features vary by plan. Its B2B functionality includes companies, catalogs, net payment terms, self-serve ordering, and Shopify Flow automations. Shopify Plus adds capabilities such as direct catalog assignment to specific companies and company locations and more advanced payment functionality.
Shopify can therefore be attractive for businesses that want faster implementation.
Potential development budget:
₹5 lakh to ₹20 lakh+
depending on customization and integrations.
The platform subscription is separate from development cost.
Adobe Commerce is designed for more sophisticated commerce environments.
Its B2B functionality supports:
Adobe describes B2B as an integrated capability supporting both B2B and B2C commerce, including customer-specific catalogs and pricing.
Adobe Commerce can be appropriate for organizations with complex catalogs, pricing, integrations, and enterprise requirements.
Development costs can range from:
₹15 lakh to ₹50 lakh+
depending on complexity.
Licensing and platform costs are separate.
Salesforce B2B Commerce is particularly relevant to businesses already operating inside the Salesforce ecosystem.
Its B2B capabilities include account and buyer segmentation, negotiated pricing, personalized catalogs, order management, and complex purchasing workflows.
Salesforce’s current B2B Commerce pricing page lists Growth and Advanced editions as “Contact for Pricing.” The editions include different capabilities such as storefront limits, inventory locations, order-management functionality, analytics, Data Cloud credits, and Agentforce capabilities. Salesforce also states that Commerce Cloud Growth and Advanced pricing can include a percentage of GMV depending on the commerce functionality required.
A Salesforce implementation can therefore have three distinct cost categories:
A realistic implementation budget can range from:
₹20 lakh to ₹60 lakh+
for more sophisticated implementations.
WooCommerce can be an attractive option for smaller businesses that want more control over their ecommerce infrastructure.
B2B functionality can be implemented through:
A basic implementation may cost:
₹5 lakh to ₹12 lakh
while a heavily customized implementation can reach:
₹15 lakh to ₹25 lakh+
The biggest consideration is usually how many third-party extensions and custom integrations are required.
A fully custom B2B portal gives the business maximum control.
The development team can build:
The downside is cost.
A custom B2B ecommerce system can easily require:
₹20 lakh to ₹60 lakh+
and enterprise projects can exceed:
₹1 crore
depending on requirements.
Here is another useful way to estimate the budget.
| Feature | Approximate Cost |
| UI/UX design | ₹1L to ₹4L |
| Company accounts | ₹1L to ₹3L |
| Buyer roles | ₹75K to ₹3L |
| Customer-specific pricing | ₹1.5L to ₹5L |
| Product catalog | ₹1L to ₹4L |
| Bulk ordering | ₹50K to ₹2L |
| Quick order | ₹50K to ₹2L |
| Quote management | ₹1L to ₹3L |
| Approval workflow | ₹1L to ₹4L |
| Credit limits | ₹1L to ₹4L |
| Purchase orders | ₹75K to ₹3L |
| ERP integration | ₹2L to ₹8L+ |
| CRM integration | ₹1L to ₹5L+ |
| Advanced search | ₹75K to ₹4L |
| Inventory integration | ₹1L to ₹5L |
| Shipping integration | ₹75K to ₹3L |
| Sales rep portal | ₹1L to ₹5L |
| Analytics | ₹75K to ₹4L |
| Mobile application | ₹5L to ₹15L+ |
These numbers should not be added mechanically.
Some features are bundled into platforms, while others require custom development.
India remains a popular development destination because businesses can access experienced development teams at different pricing levels.
Typical development rates vary significantly depending on:
A rough planning model can look like this:
| Development Team | Indicative Hourly Rate |
| Junior freelancer | ₹500 to ₹1,000 |
| Mid-level freelancer | ₹1,000 to ₹2,000 |
| Senior specialist | ₹2,000 to ₹4,000 |
| Small development agency | ₹1,500 to ₹3,500 |
| Specialized agency | ₹2,500 to ₹5,000+ |
| Enterprise consulting team | ₹4,000 to ₹8,000+ |
These are broad planning figures rather than standardized market rates.
The cheapest developer is not automatically the cheapest project.
A developer who charges ₹800 per hour but needs 2,000 hours can cost more than a specialist charging ₹2,000 per hour who completes the project in 700 hours.
A professional B2B ecommerce implementation can involve several specialists.
A typical team might include:
Not every project needs all of these people full-time.
A small B2B portal may use:
3 to 5 people
An enterprise implementation can involve:
8 to 20+ specialists
across different phases.
Development time depends on complexity.
| Project Type | Approximate Timeline |
| Basic B2B portal | 3 to 4 months |
| Standard B2B portal | 4 to 6 months |
| Advanced B2B portal | 6 to 9 months |
| Enterprise platform | 9 to 15+ months |
| Complex multi-country system | 12 to 18+ months |
These timelines assume proper planning and availability of the required business, product, customer, ERP, and integration information.
ERP integrations can become a major source of delay if APIs or data structures are not ready.
Businesses do not necessarily need to build every feature on day one.
A B2B MVP can focus on the features that directly support online ordering.
A reasonable MVP could include:
A practical MVP budget could be:
₹8 lakh to ₹15 lakh
The portal can then evolve based on actual customer behavior.
A small distributor might allocate:
| Component | Budget |
| Discovery | ₹50,000 |
| UI/UX | ₹1,00,000 |
| Frontend | ₹1,50,000 |
| Backend | ₹2,00,000 |
| B2B features | ₹1,50,000 |
| Integration | ₹1,25,000 |
| Testing | ₹50,000 |
| Deployment | ₹25,000 |
| Contingency | ₹1,00,000 |
| Total | ₹10 lakh |
This type of budget is suitable for a focused portal rather than an enterprise procurement ecosystem.
A growing manufacturer could allocate:
| Component | Budget |
| Discovery and architecture | ₹1.5L |
| UI/UX | ₹2L |
| Frontend | ₹3L |
| Backend | ₹4L |
| B2B pricing | ₹2L |
| Company accounts and permissions | ₹1.5L |
| Quote and approval workflow | ₹2L |
| ERP integration | ₹3L |
| CRM integration | ₹1.5L |
| Search and catalog | ₹1.5L |
| QA and security | ₹1L |
| Deployment and contingency | ₹2L |
| Total | ₹25 lakh |
This can support a significantly more sophisticated B2B commerce operation.
An enterprise manufacturer may need:
Such a system could require:
₹40 lakh to ₹60 lakh+
in initial implementation.
The development quotation is not the total investment.
Businesses should account for additional costs.
Depending on the platform, licensing or subscription fees may apply.
For example, Salesforce currently lists its B2B Commerce Growth and Advanced editions as contact-for-pricing products rather than publishing a simple fixed license price.
Hosting costs depend on:
Small systems can operate with relatively modest infrastructure.
Enterprise commerce systems may require:
Businesses may need subscriptions for:
These recurring expenses should be included in the total cost of ownership.
B2B ecommerce platforms require ongoing maintenance.
Annual maintenance can include:
A reasonable planning model is approximately:
15% to 25% of initial development cost annually
for maintenance and ongoing development, although actual support contracts vary considerably.
B2B portals contain sensitive commercial information.
Potentially sensitive data includes:
Security should therefore be included from the beginning.
Potential requirements include:
Enterprise systems may also require penetration testing and compliance audits.
B2B ecommerce SEO is frequently overlooked.
A portal may have thousands of product pages.
The platform should support:
However, not every B2B product page should necessarily be publicly indexed.
Some products and prices may only be available after login.
SEO strategy therefore needs to be aligned with the business model.
B2B buyers do not want to wait several seconds for every search.
Performance becomes especially important when the catalog contains:
10,000+
or:
100,000+
products.
Performance engineering may involve:
The larger the catalog and traffic volume, the more important this becomes.
If a company already has an ecommerce system, ERP, spreadsheet-based product catalog, or CRM, data migration may become a major project.
Potential migration data includes:
Data cleaning can sometimes take longer than expected.
Poor product data can delay the entire project.
There are several practical ways to control the budget.
Do not build every possible feature immediately.
Start with:
Then add advanced workflows after validating customer demand.
If a platform already supports:
there may be little reason to build those functions from scratch.
Adobe Commerce, for example, already provides multiple B2B features as part of its B2B capabilities.
Shopify similarly provides native B2B functionality across supported plans.
Custom development should solve a real business requirement.
It should not be added simply because a custom solution feels more sophisticated.
For example:
If the platform already provides a reliable company-account system, rebuilding it from scratch may add unnecessary cost.
Custom development becomes more justified when the business has genuinely unique requirements.
If the ERP already manages:
the ecommerce platform should usually integrate with the ERP instead of creating a duplicate system.
This reduces data inconsistency.
A distributor, manufacturer, wholesaler, and B2B marketplace may all be called B2B businesses.
But their requirements can be very different.
A distributor might need:
A manufacturer might additionally need:
A B2B marketplace may need:
Therefore, requirements should come before technology selection.
| Factor | SaaS Platform | Custom Development |
| Initial cost | Lower | Higher |
| Launch speed | Faster | Slower |
| Customization | Moderate | Very high |
| Maintenance | Lower | Higher |
| Infrastructure | Mostly managed | More responsibility |
| Unique workflows | Limited to supported/custom features | Easier |
| Enterprise flexibility | Depends on platform | Very high |
| Long-term control | Platform-dependent | Greater |
For many businesses, SaaS or established commerce platforms are financially attractive because they reduce the amount of infrastructure that has to be built and maintained.
Custom development becomes more compelling when the business process itself is a competitive advantage.
The purpose of a B2B ecommerce portal is not simply to create an online store.
The objective is usually to improve the economics of selling to business customers.
Potential benefits include:
Suppose a business currently has 10 sales employees manually processing orders.
If ecommerce automation significantly reduces repetitive order-entry work, the business can redirect employees toward:
This is where B2B ecommerce ROI can become much more significant than simply counting online sales.
A basic model can be:
Annual benefit = labor savings + incremental revenue + error reduction + operational savings
Then:
ROI = (Annual benefit – annual platform cost) ÷ total investment × 100
For example, suppose a company invests:
₹20 lakh
in a B2B ecommerce portal.
If the system produces:
₹8 lakh annual operational savings
and:
₹10 lakh additional annual gross profit
the annual financial benefit would be:
₹18 lakh
The payback period would depend on ongoing costs and whether the additional revenue is incremental.
This is more useful than comparing development quotations solely by price.
Before selecting a development partner, ask:
B2B ecommerce requires different expertise from conventional D2C stores.
Ask for an explanation of the pricing architecture.
Clarify:
Ask whether the team has experience with your specific ERP.
This is important for custom development.
Ask whether the quote includes:
Clarify:
Ask about:
Ask for a complete list of:
A B2B portal should not simply be a consumer ecommerce website with a “Wholesale” button.
B2B customers have different requirements.
If the ERP remains the operational source of truth, the ecommerce platform should be designed around that reality.
Pricing is often one of the most complex parts of B2B commerce.
It should be defined early.
A company may have several people involved in procurement.
The system should reflect the real approval structure.
B2B customers often buy repeatedly.
The portal should make repeat purchases extremely easy.
Poor product and customer data can create significant delays.
An attractive interface cannot compensate for:
B2B ecommerce is primarily a business system.
If the budget is limited, prioritize:
Then add:
as the business grows.
| Business | Suggested Initial Budget |
| Small wholesaler | ₹8L to ₹12L |
| Growing distributor | ₹12L to ₹20L |
| Regional manufacturer | ₹15L to ₹25L |
| National distributor | ₹20L to ₹40L |
| Enterprise manufacturer | ₹30L to ₹60L+ |
| Multi-country business | ₹40L to ₹80L+ |
| Highly customized enterprise | ₹50L to ₹1Cr+ |
Again, these are planning ranges rather than fixed quotes.
The development budget is only the initial investment.
A better financial model is:
Total Cost of Ownership = Development + Platform + Hosting + Integrations + Maintenance + Security + Support + Future Development
For example:
A company might spend:
₹20 lakh
on initial development.
Then:
₹3 lakh/year
on hosting, maintenance, monitoring, and support.
And:
₹2 lakh/year
on third-party services.
Its three-year cost could therefore be considerably higher than the initial ₹20 lakh development quotation.
This is why businesses should compare projects using three-year or five-year TCO rather than only the initial development price.
A practical 2026 planning range is approximately ₹8 lakh to ₹30 lakh+. Advanced and enterprise implementations can exceed ₹30 lakh and may reach ₹50 lakh, ₹1 crore, or more depending on integrations and complexity.
A basic B2B portal can start around ₹8 lakh to ₹12 lakh when it includes company accounts, catalog, customer-specific pricing, ordering, and basic administration.
A custom B2B ecommerce portal can cost approximately ₹15 lakh to ₹40 lakh+. Enterprise systems can exceed this range.
A major ERP integration can cost approximately ₹2 lakh to ₹8 lakh+, depending on the ERP, API architecture, data volume, synchronization requirements, and business workflows.
Usually, yes.
B2B portals commonly require additional functionality such as company accounts, buyer permissions, customer-specific pricing, quotes, purchase orders, credit management, approval workflows, and ERP integrations.
A basic portal may take around 3 to 4 months, while a standard system can take 4 to 6 months. Advanced and enterprise implementations can take 6 to 15+ months.
Yes. Shopify provides native B2B functionality on supported plans, including companies, catalogs, payment terms, and self-service ordering. The exact feature set depends on the plan.
Yes. Adobe Commerce provides B2B capabilities including company accounts, shared catalogs, customer-specific pricing, quick ordering, requisition lists, and B2B quotes.
Yes. Salesforce B2B Commerce supports company and buyer experiences, personalized pricing, catalogs, order management, and other B2B commerce functionality. Salesforce currently lists B2B Commerce Growth and Advanced editions with contact-based pricing.
Custom development makes more sense when the company’s workflows, pricing, procurement, integrations, or customer experience require functionality that existing platforms cannot provide efficiently.
For straightforward B2B requirements, an established commerce platform can reduce initial development effort.
Usually, it is not the number of pages.
The biggest cost drivers are:
The cost to build a B2B ecommerce portal depends primarily on what happens behind the storefront.
A simple B2B ordering portal may cost approximately:
₹8 lakh to ₹12 lakh
A standard B2B commerce platform may require:
₹12 lakh to ₹20 lakh
A more sophisticated implementation can cost:
₹20 lakh to ₹40 lakh+
Enterprise B2B commerce systems can reach:
₹30 lakh to ₹60 lakh+
while highly customized global commerce ecosystems can exceed:
₹1 crore
The biggest mistake is choosing a budget before defining the business workflow.
A B2B ecommerce portal should be designed around the way customers actually purchase.
That means understanding:
The platform should then be selected based on those requirements.
For a small wholesaler, building a ₹50 lakh system may create unnecessary complexity.
For an enterprise manufacturer, trying to build a sophisticated procurement platform for ₹5 lakh can create limitations that become expensive to fix later.
The right B2B ecommerce budget is therefore not the cheapest quotation.
It is the investment required to create a reliable digital purchasing system that matches the company’s commercial processes and can scale with its customers.
In 2026, businesses should evaluate B2B ecommerce projects based on total cost of ownership, integration complexity, scalability, security, usability, and long-term operational value, not simply the initial development quote.
