The verdict in three sentences
A B2B partner extranet for a network of 120 resellers costs between EUR 35,000 and 80,000 in 2026, delivered in 4 to 6 months. ERP integration (Sage, SAP) accounts for 20-30% of the budget and drives the real gain. Once online self-ordering is live, sales-admin workload drops 30-50% and processing goes from 2-3 days to a few hours.
What a partner extranet costs in 2026
The price depends on the number of roles, the granularity of the per-reseller catalogue and the depth of ERP integration. 2026 orders of magnitude.
| Scope | Key functions | Cost | Timeline |
|---|---|---|---|
| Essential | Shared catalogue, cart, orders | EUR 35,000-50,000 | 4 months |
| Standard | + per-reseller catalogue/pricing, roles | EUR 50,000-65,000 | 4-5 months |
| Advanced | + ERP integration, credit, documents | EUR 65,000-80,000 | 5-6 months |
| Full | + PWA, analytics, marketing assets | EUR 80,000+ | 6-7 months |
Maintenance (TMA) is around 10% of project cost per year, i.e. EUR 3,500-8,000/year.
The line items that weigh on the budget
In a distribution network, integration and fine-grained rights are the real cost levers.
| Item | Budget impact | Note |
|---|---|---|
| ERP integration (Sage/SAP) | +20-30% of project | Stock, pricing, credit in real time |
| Per-reseller catalogue and pricing | +EUR 8,000-18,000 | Differentiated grids |
| Role and permission management | +EUR 5,000-12,000 | Admin, sales, reseller |
| Credit / outstanding tracking | +EUR 4,000-9,000 | Automatic blocking |
| Downloadable marketing assets | +EUR 3,000-7,000 | Sheets, visuals, POS |
Mini case study
Nathalie, network director of an equipment distributor in Amsterdam (120 resellers), runs a 5-person sales-admin team that keys 2,400 orders/month received by email and phone. Each order takes 12 minutes to enter, i.e. 480 h/month. At a loaded cost of EUR 26/h, that is roughly EUR 12,480/month.
She invests EUR 62,000 in an extranet with per-reseller catalogue and ERP integration, delivered in 5 months. 55% of orders shift to self-entry, saving 264 h/month (~EUR 6,864/month). The sales-admin team refocuses on key accounts and disputes. Payback on sales-admin savings alone: about 9 months, not counting the revenue lift from a 24/7 catalogue.

FAQ
Do I really need ERP integration?
For a real gain, yes: without real-time stock and pricing, resellers order unavailable products and sales-admin has to fix it. Integration is 20-30% of the budget but drives adoption.
Can I set different pricing per reseller?
Yes, via pricing grids by group or account. Budget EUR 8,000-18,000 depending on the complexity of discounts, tiers and negotiated terms.
How many resellers can the extranet handle?
A sound architecture handles thousands of accounts without issue. Cost depends not on the number of resellers but on the number of functions and roles.
What is a realistic go-live timeline?
4 to 6 months for a standard extranet with ERP integration. A first release (catalogue + orders) can ship in 3 months, with integration following in phase 2.
How do I onboard 120 phone-habit resellers?
With progressive onboarding: short training, concrete benefits (24/7 availability, history, documents) and incentives (discount on online orders in the early months). Adoption often reaches 50-70% within 3 months.
