How much a B2B e-commerce costs in 2026
Updated September 1, 2026
The mistake that inflates or sinks most B2B quotes is treating it as B2C with a discount. A serious B2B store is a different machine: each customer has their own price list and terms, orders follow credit limits and approvals, fast reordering matters more than the storefront, and everything must stay aligned with the ERP. That — not the graphics — is where the cost is decided.
The price ranges
B2B on a standard platform
€8,000 – €20,000
Shopify B2B or WooCommerce with extensions: tiered price lists, order approval, reserved catalogue. Fine when commercial rules are simple.
B2B integrated with the ERP
€20,000 – €45,000
Prices, stock and orders synced with the ERP; each customer sees THEIR price and THEIR documents. Where most serious projects land.
Custom B2B portal
€45,000 – €100,000
Complex catalogues (spare-part diagrams, configurators), multi-warehouse, agent networks, commercial rules no standard platform covers.
The single heaviest item is almost always ERP integration: it depends more on how open YOUR ERP is than on the developer’s skill.
The real differences from B2C
- Per-customer prices and terms: not one price — a hundred. Price list management is the heart of the project.
- Orders with rules: minimums, pack multiples, credit limits, approvals. The cart is the easy part.
- Reordering first: B2B customers buy the same things every month — code lists, copy order, CSV. If reordering is slow, the portal dies.
- VAT, e-invoicing and 30/60/90-day payments: Italian B2B checkout has its own rules.
Where to start without failing
The path that works: first the records-prices-stock integration (the foundation — it alone already empowers the sales network), then online orders for a pilot group of trusted customers, then everyone. Projects that start from the graphics and leave the ERP "for later" end up doubled in time and cost.
Frequently asked questions
Can I use Shopify for B2B?
Yes, for simple commercial rules: Shopify has native B2B features (price lists, companies, draft orders). When complex credit rules, configurators or spare-part diagrams come in, custom development on top or alongside is needed.
How much does ERP integration cost?
€5,000 to €20,000 depending on how open the ERP is: a modern one with APIs integrates in weeks, a closed one needs extraction work. It is the question to ask BEFORE choosing the platform.
Does online B2B make sense for an SME with 200 customers?
Often yes, but not to sell more: to stop retyping orders by hand. With 200 active customers the portal pays for itself in saved hours and avoided errors before any new sales.
