The verdict in three sentences
A partner and reseller extranet costs in 2026 between 30,000 and 80,000 EUR for a Dublin manufacturer equipping 200 resellers, with a 4-to-6-month timeline. The most structuring item is the ERP connector (pricing, stock, orders), which often accounts for 20 to 35 % of the budget. The return comes from freed-up sales time: 2 to 4 hours/week per rep who no longer answers price and availability requests.
How much a reseller extranet costs in 2026
The cost depends on the number of roles, the level of pricing personalization and the integration with the information system. Here are the 2026 orders of magnitude for a B2B network.
| Scope | Key features | Timeline | Budget EUR |
|---|---|---|---|
| Catalogue extranet | Auth, pricing, technical docs | 3-4 months | 30,000 - 45,000 |
| Ordering extranet | + cart, orders, tracking | 4-5 months | 45,000 - 60,000 |
| Integrated extranet | + real-time ERP connector, fine roles | 5-6 months | 60,000 - 80,000 |
| Multi-country extranet | + multi-currency, multilingual, discounts | 6-8 months | 80,000 - 120,000 |
The ERP connector (SAP, Sage, Cegid, Odoo) is the item to watch: budget 8,000 to 20,000 EUR depending on the quality of the available API. An ERP without a modern API can double that cost.
ROI: sales time and errors avoided
The extranet removes email and phone back-and-forth on prices, stock and documents. The table quantifies the gain for 8 reps.
| Item | Before extranet | After extranet | Annual gain |
|---|---|---|---|
| Price/stock requests handled | 3 h/wk/rep | 0.5 h/wk/rep | 20 h/wk team |
| Sales time cost (40 EUR/h) | — | — | ~41,600 EUR |
| Order errors | 4 %/month | 1 %/month | ~9,000 EUR |
| Order processing time | 24 h | 2 h | — |
| Annual maintenance (18 %) | — | -9,900 EUR | -9,900 EUR |
| Net year 1 | — | — | ~40,700 EUR |
For an investment of 55,000 EUR and a net gain of about 40,700 EUR/year, the extranet is amortized in 16 to 18 months, not counting the rise in orders linked to 24/7 availability.
Mini case study
Pierre runs an industrial components manufacturer in Dublin, with 200 resellers and 8 reps. Each rep spends about 3 h/week answering the same questions by email: net price, availability, datasheet. He invests 55,000 EUR in an ordering extranet with a Sage connector, delivered in 5 months.
After deployment, time spent drops to 0.5 h/week per rep, i.e. 20 h/week returned to the team. Valued at 40 EUR/h, that is ~41,600 EUR/year, plus 9,000 EUR of order errors avoided. Net of maintenance (9,900 EUR/year), the gain is ~40,700 EUR/year and the extranet pays back in under 18 months.

FAQ
Do we absolutely need to connect the ERP?
Not to start, but that is where the real value hides. Without a connector, prices and stock are entered manually and go stale fast. A real-time connector (8,000 to 20,000 EUR) avoids orders on non-existent stock.
How do we manage 200 resellers with different prices?
Through a system of roles and pricing grids: each reseller sees their net price according to segment, volume or contract. It is a B2B extranet standard, planned from scoping.
Can the extranet be opened internationally?
Yes: multi-currency, multilingual and per-country discount rules. Budget an extra 20,000 to 40,000 EUR for a full multi-country version.
How long to train resellers?
A well-designed extranet requires no heavy training. Still plan a 30-min video call and a PDF guide; adoption usually reaches 70 to 85 % of resellers within 3 months.
What is the maintenance cost?
About 15 to 20 % of the initial budget per year, i.e. 8,250 to 11,000 EUR for a 55,000 EUR project, including ERP connector evolution and security.
