The verdict in three sentences
A B2B extranet for resellers (catalogues, negotiated prices, orders) is priced between 24,000 and 45,000 EUR in 2026 in Dublin, delivered in 12 to 18 weeks. The heavy line items are the business modules (12,000-25,000 EUR) and the ERP integration (5,000-12,000 EUR). Then plan for maintenance of 800 to 1,500 EUR/month: a serious quote clearly separates build and run.
Anatomy of a B2B extranet quote
The quote should break out each item with a precise scope. Here is the 2026 reference structure for a reseller extranet.
| Quote line | Scope | EUR range |
|---|---|---|
| Discovery & specs | Workshops, backlog, mockups | 3,000 - 6,000 |
| Authentication & roles | SSO, profiles, per-client pricing | 4,000 - 8,000 |
| Catalogue & negotiated prices | Product sheets, per-account rates | 5,000 - 10,000 |
| Order taking | B2B cart, thresholds, approval | 5,000 - 12,000 |
| ERP integration | Stock, pricing, orders | 5,000 - 12,000 |
| QA & deployment | Testing, training, go-live | 2,000 - 5,000 |
| Build total | 24,000 - 45,000 |
What makes the price move
Three levers explain the gap between a 24,000 and a 45,000 EUR quote: the number of roles, the depth of ERP integration and the level of order automation.
| Factor | Economy version | Advanced version |
|---|---|---|
| Roles / profiles | 2-3 profiles | 6+ granular profiles |
| SSO | Simple login | SAML / OIDC SSO |
| ERP integration | Scheduled CSV export | Real-time two-way API |
| Negotiated prices | Fixed grids | Dynamic per-account rules |
| Orders | Manual approval | Automated workflow + stock |
| Maintenance / month | 800 - 1,000 EUR | 1,100 - 1,500 EUR |
Mini case study
Nadia, IT manager of an industrial distributor in Dublin (40 active resellers), handles 300 orders/month by email and phone. Each order needs about 18 minutes of re-keying, i.e. 90 hours/month; at 32 EUR/hour loaded, that is 34,560 EUR/year. She invests 36,000 EUR in an extranet with real-time ERP integration, delivered in 15 weeks, plus 1,200 EUR/month maintenance. Re-keying drops by 70%, saving 24,200 EUR/year, and order errors fall sharply. First-year cost: 36,000 + 14,400 = 50,400 EUR; operational payback around month 25, then a net gain of about 9,800 EUR/year.
