B2B ecommerce website development in India typically costs ₹4 to 12 lakh for a standard wholesale portal and ₹15 to 35 lakh+ for a custom platform with ERP integration, and takes 10 to 24 weeks to launch. The price gap comes down to one thing: how much of your existing pricing, credit and inventory logic has to be rebuilt inside the website rather than bolted on top of it. (For a quick scope-based range of your own, use our project cost estimator.)
If you sell to dealers, distributors, retailers or institutional buyers, a B2C store template will not do the job. B2B buying involves negotiated rates, GST-compliant invoicing, credit terms, minimum order quantities and repeat ordering - none of which a standard Shopify or WooCommerce install handles out of the box.
Key Takeaways
- Cost: ₹4 to 12 lakh for a standard B2B portal; ₹15 to 35 lakh+ for custom builds with ERP/Tally integration.
- Timeline: 10 to 14 weeks for a standard build, 20 to 24 weeks when ERP and multi-warehouse inventory are in scope.
- The market is moving: India's B2B ecommerce segment is forecast to grow at a 16.87% CAGR through 2031, outpacing B2C (Mordor Intelligence, 2026).
- Buyers expect it: Among B2B companies that offer ecommerce, 34% of revenue now comes from that channel - more than in-person sales (McKinsey B2B Pulse, 2024).
- Compliance is non-negotiable: GST e-invoicing applies at ₹5 crore turnover, and businesses above ₹10 crore must report invoices to the IRP within 30 days (effective 1 April 2025).
- Biggest cost driver: ERP/accounting integration, not design.
Why B2B ecommerce has stopped being optional in India
For years, Indian B2B sellers assumed their buyers preferred phone calls and WhatsApp order lists. The data says otherwise.
McKinsey's 2024 B2B Pulse Survey - roughly 4,000 decision makers across 34 sectors in 13 countries - found what it calls the "rule of thirds": at any stage of the buying journey, one-third of buyers want in-person contact, one-third want remote contact, and one-third want digital self-service. That split holds across geographies, industries, company sizes and deal values.
Three other findings matter for anyone budgeting a build:
- 71% of B2B organisations now offer some form of ecommerce, and among those, online channels generate 34% of total revenue - overtaking in-person sales as the top revenue channel.
- Buyers use an average of ten interaction channels in a single buying journey, up from five in 2016.
- More than half of respondents said they would switch suppliers if the experience across those channels was not smooth. Among the most digitally demanding buyer group, that figure rose to 65%.
In the Indian context, the direction is the same. Mordor Intelligence projects the B2B slice of India's ecommerce market to grow at a 16.87% CAGR from 2026 to 2031, faster than the consumer segment, as procurement digitises. Redseer has separately estimated India's eB2B market reaching US$90 to 100 billion in GMV by 2030 (reported via IBEF, 2022 - treat as a directional forecast given its age).
The practical translation: your competitor's distributor portal is not a nice-to-have. It is where a third of your buyers would rather place their reorders at 11 pm without calling anyone.
What a real B2B ecommerce website needs (that a B2C store doesn't)
This is the section most cost estimates skip, and it's exactly where budgets get blown. A B2B build is defined by its business rules, not its homepage.
Customer-specific pricing and price lists
Every dealer sees a different rate. Your platform needs price-list logic tied to customer groups, slab-based discounts, and often contract pricing for named accounts. Hiding prices from logged-out visitors is usually a requirement too.
Login-gated catalogue and account approval
New buyers register, you verify their GSTIN and trade references, then approve them. Guest checkout typically does not exist.
Minimum order quantities, pack sizes and bulk grids
Buyers order in cartons, not units. A "quick order" grid - where a buyer types SKU codes and quantities into a spreadsheet-style form - converts far better than a B2C product page for repeat purchasers.
Credit terms and part payments
Many Indian B2B relationships run on 30/45/60-day credit. The site needs to support credit-limit checks, purchase-order uploads, and "place order now, invoice later" flows alongside prepaid options.
GST-compliant invoicing and e-invoicing
This is a hard compliance requirement, not a feature. E-invoicing under GST applies to businesses with aggregate turnover above ₹5 crore, covering B2B transactions, exports and supplies to government departments. Since 1 April 2025, businesses with turnover of ₹10 crore or more must report invoices to the Invoice Registration Portal within 30 days of the invoice date - after that window, the portal rejects them. Your platform has to generate the invoice, push it to the IRP, and store the IRN and QR code against the order.
ERP, Tally and inventory sync
If stock, pricing and dispatch live in Tally, SAP, Zoho Books or a custom ERP, the website must read from and write to it. Real-time or near-real-time sync is what separates a working portal from a glorified order form your ops team re-enters by hand.
Reorder, order history and downloadable ledgers
Repeat ordering is the whole point. Buyers want their last 12 orders, a one-click repeat button, and a downloadable statement of account. Most of this rule engine is custom web application work, not a theme setting.
B2B ecommerce website cost in India (2026)
Below are the ranges we see quoted across Delhi NCR - Gurgaon, Noida and Delhi - for the Indian market in 2026. Treat them as planning ranges, not fixed quotes; scope decides the number.
| Build type | What it covers | Typical cost (INR) | Timeline |
|---|---|---|---|
| Starter B2B portal | Login-gated catalogue, customer groups, basic tiered pricing, MOQ, manual invoicing. Built on WooCommerce B2B or Shopify with a B2B app. | ₹1.5 to 4 lakh | 5 to 8 weeks |
| Standard B2B ecommerce site | Everything above, plus quote requests, credit terms, GST e-invoicing, payment gateway, order approval workflows, basic ERP/Tally sync. | ₹4 to 12 lakh | 10 to 14 weeks |
| Custom B2B platform | Bespoke frontend, deep ERP/SAP integration, multi-warehouse inventory, multi-branch users with roles, sales-rep ordering, custom pricing engine, mobile app for field staff. | ₹15 to 35 lakh+ | 20 to 24 weeks |
| Ongoing maintenance / AMC | Hosting, security patching, compliance updates, backups, small enhancements. | ₹15,000 to 75,000 per month | Ongoing |
Where the budget actually goes. On most projects we scope, design accounts for 15 to 20% of the cost. Integration - ERP, payments, logistics, e-invoicing - regularly accounts for 35 to 50%. If an agency quotes you a low number without asking which ERP you run, the integration cost hasn't been priced in yet. For the B2C side of these numbers, see our ecommerce website development cost in India guide.
One number worth knowing: digitised B2B ordering with tax-compliant audit trails has been observed shrinking working-capital cycles from 45 to 60 days to under 20 days, according to Mordor Intelligence's 2026 India ecommerce analysis. For a distributor doing ₹20 crore a year, that cash-flow shift usually dwarfs the build cost.
Choosing a platform: what fits which business
There is no single best B2B platform in India. There's a best fit for your order volume, catalogue size and ERP.
WooCommerce + B2B extensions
Best for: catalogues under ~5,000 SKUs, budgets under ₹6 lakh, businesses that want full ownership and no per-order platform fee. Watch out for: plugin sprawl. Every B2B rule you add is another plugin to maintain. Performance degrades fast on large catalogues without proper caching and database tuning.
Shopify B2B (all paid plans)
Worth knowing: since 2 April 2026, Shopify's core B2B features are no longer Plus-only. Companies, company locations, net payment terms, quantity price breaks, PO numbers, the quick order list and sales-staff permissions are now available on Basic, Grow and Advanced too (Shopify Help Center - B2B features by plan).
Best for: brands already running D2C on Shopify who want a wholesale channel alongside it, and teams that want zero infrastructure management. The economics of this option improved sharply in 2026 - our Shopify development guide for Gurgaon covers build costs and vetting. Watch out for: the Plus-only limits still matter at scale. Non-Plus plans cap you at 3 active B2B catalogs, and direct catalog assignment to a specific company or location - the mechanism for true customer-specific pricing - remains Plus-only, as do deposits and partial payments. If every dealer needs their own price list, you need Plus.
Adobe Commerce
Best for: large catalogues, multi-warehouse operations, companies with in-house tech capacity. The B2B module ships company accounts with sub-users, shared catalogues, negotiable quotes and requisition lists as native functionality. Important distinction: these B2B features come with a paid Adobe Commerce licence. Magento Open Source has no native B2B module - every one of those capabilities has to be added via third-party extensions or custom development, which is a real and often underestimated cost line. Watch out for: licence, hosting and developer cost. This is the highest total-cost-of-ownership option on the list.
Custom build (Next.js / Laravel / Node + headless)
Best for: businesses whose pricing or approval logic doesn't fit any platform's model, or who need a portal, a mobile app and an ERP to behave as one system. If you're weighing a custom stack, our Next.js vs WordPress comparison covers the trade-offs. Watch out for: you are funding everything, including the admin panel. Only justified when off-the-shelf genuinely blocks the business.
Payments and logistics for B2B in India
B2B order values are high, which changes the payment mix. UPI dominates Indian digital payments overall - NPCI recorded 228 billion UPI transactions in 2025 - but per-transaction limits mean high-value B2B orders often route through NEFT/RTGS, corporate net banking, or credit-terms flows rather than UPI or cards.
Practical guidance for the build:
- Offer bank transfer with reference-number reconciliation alongside a gateway. Many buyers will use it.
- Support partial payment / advance + balance on large orders.
- Build credit-limit checks at checkout, not after.
- Integrate a logistics aggregator for LTL/FTL freight, and show buyers real dispatch and e-way bill status.
Choosing the right gateway matters more here than in B2C - see our comparison of the best payment gateways for ecommerce in India.
How long does a B2B ecommerce build take?
A realistic timeline for a standard build:
- Discovery and business-rule mapping - 2 weeks. Pricing tiers, customer groups, credit policy, approval chains. Do this badly and everything downstream slips.
- UX and design - 2 to 3 weeks. Focus on the quick-order grid and account dashboard, not the homepage hero.
- Development - 5 to 8 weeks. Catalogue, pricing engine, checkout, roles.
- Integrations - 3 to 5 weeks, overlapping. ERP, e-invoicing, payments, logistics. This is where slippage happens.
- UAT with real dealers - 2 weeks. Give five actual buyers real orders to place; they find what QA won't.
- Launch and stabilisation - 1 to 2 weeks.
Pilot with 10 to 20 friendly dealers before announcing the portal to your full network. First-run order errors cost trust that takes months to rebuild.
Frequently Asked Questions
How much does a B2B ecommerce website cost in India?
A standard B2B ecommerce website in India costs ₹4 to 12 lakh in 2026, covering login-gated catalogue, tiered pricing, GST e-invoicing, payment gateway and basic ERP sync. Simpler wholesale portals start around ₹1.5 lakh, while custom platforms with deep ERP integration and a field-sales app run ₹15 to 35 lakh or more.
Can I use Shopify or WooCommerce for a B2B website in India?
Yes, for most small and mid-sized distributors. Since April 2026, Shopify's native B2B features - company accounts, net payment terms, volume pricing and quick order lists - are available on all paid Shopify plans, not just Plus, though customer-specific catalog assignment and unlimited catalogs remain Plus-only. WooCommerce supports B2B through extensions. Both work well up to moderate catalogue sizes and order volumes. Businesses with complex contract pricing, multi-warehouse stock or heavy ERP dependency usually outgrow both and move to Adobe Commerce or a custom build.
Does a B2B ecommerce website need GST e-invoicing?
If your aggregate annual turnover exceeds ₹5 crore, yes - e-invoicing is mandatory for B2B supplies, exports and supplies to government departments. Businesses with turnover of ₹10 crore or more must also report invoices to the Invoice Registration Portal within 30 days of the invoice date, effective 1 April 2025. Your platform should generate the IRN and QR code automatically at the point of order confirmation.
How long does B2B ecommerce website development take?
Ten to fourteen weeks for a standard build, and 20 to 24 weeks when ERP integration, multi-warehouse inventory and a sales-rep app are in scope. Integration work - not design or development - is the most common cause of delay.
What is the difference between a B2B and B2C ecommerce website?
A B2C site sells the same product at the same price to everyone with guest checkout. A B2B site gates the catalogue behind approved logins, shows customer-specific pricing, enforces minimum order quantities, supports credit terms and purchase orders, generates GST-compliant invoices, and prioritises fast repeat ordering over discovery and browsing.
Should I hire a local agency in Gurgaon or work remotely?
Either works technically, but B2B builds involve heavy business-rule discovery with your sales and accounts teams. A Delhi NCR agency that can sit in your Gurgaon or Noida office for the discovery phase, and again during dealer UAT, tends to surface pricing and credit edge cases that get missed over video calls. Our guide to choosing a web development company in Gurgaon applies the same discipline to B2B.
The short version
If a meaningful share of your revenue comes from repeat orders by known buyers, a B2B ecommerce website pays for itself in reduced order-processing cost and faster collections - often before it pays for itself in new sales. Budget ₹4 to 12 lakh for a standard build, expect integrations to consume roughly half of it, and spend the first two weeks mapping business rules rather than picking colours.
