The verdict in three sentences
A reseller extranet's cost is steered feature tier by feature tier, not as one lump: core, catalog, ordering, ERP connector, marketing docs. A full portal runs 35,000-70,000 EUR in 2026, but a credible MVP starts far lower. The line item that swings the budget is almost always the ERP connector and the segment-based negotiated pricing logic.
Pricing by module
Opening an extranet to your resellers means stacking building blocks. Here are 2026 ballparks for a network of 20 to 150 resellers.
| Module | Cost (EUR) | Timeline |
|---|---|---|
| Auth core + roles + reseller accounts | 9,000 - 16,000 | 3-4 wks |
| Catalog + segment-based negotiated pricing | 12,000 - 24,000 | 4-6 wks |
| Ordering + B2B cart + backorders | 8,000 - 16,000 | 3-5 wks |
| ERP connector (stock, prices, orders) | 8,000 - 18,000 | 3-6 wks |
| Marketing docs + asset library | 4,000 - 9,000 | 2-3 wks |
| Full portal | 35,000 - 70,000 | 10-16 wks |
The day rate sits between 500 and 650 EUR in 2026. Segment-based negotiated pricing (volume grids, family discounts) is the main source of functional complexity.
The 3-year cost of ownership
On top of the build come hosting and maintenance. Expect managed hosting of 120 to 320 EUR/month and annual maintenance of 20% of the build.
| Line item | 2026 ballpark |
|---|---|
| Managed hosting | 120 - 320 EUR/month |
| Annual maintenance | 20% of build |
| Tier 1/2 reseller support | 300 - 900 EUR/month |
| Evolutions (quarterly batch) | 4,000 - 10,000 EUR |
| Network training (kickoff) | 1,500 - 4,000 EUR |
On a 50,000 EUR build, 20% maintenance adds 10,000 EUR/year; hosting, ~2,400 EUR/year. The 3-year TCO then exceeds 85,000 EUR, which belongs in the business case from day one.

Mini case study
Sophie, distribution network manager in Singapore (electrical equipment, 78 resellers) wants to retire email-and-PDF ordering. She scopes a 26,000 EUR MVP (core + segmented catalog + ordering) delivered in 9 weeks, with no ERP connector at launch. Each reseller places 3.2 orders/month on average; automation saves 12 minutes of data entry per order for the sales team, i.e. ~480 hours/year (≈ 14,000 EUR of workload). The 14,000 EUR ERP connector is planned for batch 2, once adoption is proven. Estimated payback: 20 months.
FAQ
Can we start without an ERP connector? Yes. An MVP with catalog import and order export already covers 80% of the need. The real-time connector (8,000-18,000 EUR) comes in batch 2 once usage is confirmed.
How do we handle per-reseller negotiated pricing? Through segment grids and product-family discounts managed in the back office. It's the most structuring module: budget 12,000 to 24,000 EUR.
Realistic timeline for a full portal? 10 to 16 weeks depending on module count and ERP API availability. An MVP can ship in 8-9 weeks.
How much is maintenance? Roughly 20% of the build per year, plus hosting (120-320 EUR/month) and Tier 1/2 support for resellers.
Do we need a mobile app? Rarely at launch. A responsive extranet (PWA) fits most networks; a native app is justified mainly for field order-taking.
