The verdict in three sentences
A B2B extranet for your distributors (personalized pricing, order entry, technical documents) costs between 25,000 and 60,000 EUR in 2026 depending on functional richness. ERP integration adds 8,000 to 15,000 EUR and drives the reliability of stock and prices. Plan 14 to 22 weeks and prioritize an MVP around the catalog + ordering pair.
The modules of a distributor extranet
A B2B extranet is not a consumer e-commerce site: prices are negotiated per client, discounts depend on volume, and technical documents must be filtered by rights. The table below lists typical modules, their cost and MVP priority.
| Module | Role | 2026 order of magnitude (EUR) | MVP priority |
|---|---|---|---|
| Catalog + personalized pricing | Price per client/segment | 6,000 - 12,000 | High |
| Order entry | B2B cart, quotas, backorders | 6,000 - 11,000 | High |
| Distributor accounts & roles | Multi-user, rights | 3,500 - 7,000 | High |
| Technical documents | Sheets, manuals, rights filter | 3,000 - 6,000 | Medium |
| After-sales / claims | Tickets, warranties | 3,500 - 7,000 | Medium |
| Order & delivery tracking | Statuses, tracking | 3,000 - 6,000 | Medium |
| Distributor dashboard | Balances, history | 2,500 - 5,000 | Low |
The weight of ERP integration
The real complexity of a B2B extranet is synchronization with the ERP: stock, prices, client balances and order statuses must stay consistent. Depending on the ERP and API availability, integration varies widely.
| Integration scenario | Approach | 2026 order of magnitude (EUR) |
|---|---|---|
| Modern ERP with REST API | Real-time connection | 8,000 - 12,000 |
| ERP with file exports | Scheduled imports | 5,000 - 9,000 |
| Legacy ERP without API | Connector/middleware | 12,000 - 20,000 |
| Complex personalized pricing | Pricing engine | +4,000 - 8,000 |
| Real-time stock sync | Webhooks/queue | +3,000 - 6,000 |
Mini case study
Karim runs a hardware manufacturer in Lille serving 140 distributors. His sales reps spend around 220 hours/month keying in orders received by email and fax, at a loaded cost of 32 EUR/hour, i.e. 7,040 EUR/month. An extranet at 48,000 EUR plus 12,000 EUR of ERP integration shifts 60 % of orders to self-service, saving ≈ 4,200 EUR/month in data entry and eliminating pricing errors. Over 24 months, the cumulative gain (≈ 100,000 EUR) far exceeds the 60,000 EUR investment, on top of the traceability gained.

Why does an extranet cost more than a brochure site?
Because prices are personalized per client, rights filter content and everything connects to the ERP. These business rules make up most of the 25,000-60,000 EUR budget.
Can we launch without ERP integration?
Yes, via daily imports of prices and stock. Real-time arrives in phase 2 for 8,000 to 15,000 EUR when volumes justify it.
What is a realistic timeline?
14 to 22 weeks for a full extranet. An MVP catalog + ordering can ship in 12 weeks.
How many distributors to break even?
From 40 to 60 active distributors placing regular orders, the savings on data entry and errors usually justify the investment.
Do we need a dedicated pricing engine?
If your discounts depend on volume, segment and specific contracts, yes: budget an extra 4,000 to 8,000 EUR for a reliable engine.
