The verdict in three sentences
A custom partner/reseller extranet in Dublin runs 45,000 to 120,000 EUR for the platform, plus 8,000 to 22,000 EUR for the ERP connector (SAP, Sage) and 6,000 to 13,000 EUR for multi-tier pricing. The tool is justified once you have more than 15-20 resellers needing differentiated prices and real-time stock. Expect 10 to 16 weeks of development and maintenance of 900 to 2,400 EUR/month.
Pricing a connected B2B extranet
A reseller extranet is not a showcase: it is a transactional tool where each partner sees their own prices, places orders and tracks their balance. Cost depends on the number of pricing rules and the depth of ERP integration.
| Module | 2026 range (EUR) | Role |
|---|---|---|
| Base extranet platform | 45,000 - 60,000 | Reseller accounts, catalogue, orders |
| Advanced version | 60,000 - 120,000 | + co-marketing, RMA, dashboards |
| ERP connector (SAP/Sage) | 8,000 - 22,000 | Sync customers, stock, orders |
| Multi-tier pricing | 6,000 - 13,000 | Tiers, discounts, segment grids |
| Real-time stock | 4,000 - 10,000 | Live availability, reservations |
| Co-marketing area | 3,000 - 9,000 | Assets, POS material, partner kits |
These amounts are a 2026 order of magnitude for an Irish manufacturing or distribution SME. A French-speaking nearshore team can deliver comparable scope at the lower end of these ranges.
Recurring costs, day rates and ROI
The extranet pays off by pushing order entry to the resellers themselves and removing re-keying between the portal and the ERP.
| Line item | 2026 range | Note |
|---|---|---|
| Developer day rate | 450 - 720 EUR | Ireland/nearshore, by seniority |
| ERP integrator day rate | 600 - 900 EUR | Scarce SAP/Sage skills |
| Maintenance | 900 - 2,400 EUR/month | By reseller count |
| Hosting EU | 130 - 480 EUR/month | GDPR, HA optional |
| Total timeline | 10 - 16 weeks | Connector included |
Each order entered directly by a reseller saves 8 to 15 minutes of back-office processing: across 400 orders/month that is dozens of hours recovered.

Mini case study
Sophie, sales director at a Dublin manufacturer (60 resellers, 450 orders/month), commissions an extranet at 66,000 EUR + a Sage connector at 15,000 EUR, so 81,000 EUR, with maintenance of 1,500 EUR/month. Before, each order went by email then a 12-minute re-key into the ERP. With the extranet, 80% of orders are entered directly by resellers: 360 orders x 12 min = 72 hrs/month saved. At 40 EUR/loaded hour that is 2,880 EUR/month, repaying the initial budget in about 30 months, net of maintenance.
FAQ
Why not use a B2B SaaS portal? B2B SaaS suits standard catalogues but hits ceilings fast on complex price grids, per-segment discount rules and deep ERP integration. Custom wins beyond 20 resellers with differentiated rules.
Is the ERP connector really necessary? Yes once you want real-time stock and no re-keying. Without it you pay in back-office hours what you save on development, 8,000 to 22,000 EUR depending on the ERP.
How long to deliver? Expect 10 to 16 weeks depending on connector and pricing-grid complexity. The ERP integration phase is usually the critical path.
Can we start without every function? Yes: many clients launch the orders + pricing base (45,000-60,000 EUR) then add co-marketing and RMA in phase 2. This spreads the investment.
What maintenance budget should we plan? From 900 to 2,400 EUR/month depending on reseller count and change frequency. The larger your network, the more maintenance is justified.
