The verdict in three sentences
A custom supplier extranet for a manufacturer in Amsterdam costs between EUR 25,000 and EUR 55,000 in 2026, depending on the number of modules and the depth of ERP integration. The triad RFQ + order tracking + ERP connection is the value core and targets -40% processing time on supplier orders. Plan for 16 to 20 weeks, with ROI usually reached in under 18 months for volumes of several hundred orders a month.
The cost breakdown in 2026
A supplier extranet digitizes requests for quotes (RFQ), orders, acknowledgements and invoicing. Here are the 2026 order-of-magnitude ranges for a mid-sized manufacturer.
| Module | Function | Cost 2026 (EUR) |
|---|---|---|
| Extranet (core) | Supplier accounts, roles, dashboard | 25,000 - 55,000 |
| RFQ module | Tenders, responses, comparison | 8,000 |
| Order tracking | Statuses, acknowledgements, deliveries | 6,000 |
| ERP connection | Two-way sync (SAP, Sage, Dynamics) | 10,000 |
| Document portal | Certificates, drawings, quality contracts | 4,000 |
| Notifications + reminders | Automated email/SMS | 2,500 |
The core varies with the number of suppliers and languages. A Starter version at EUR 25,000 handles accounts, orders and documents; a full version at EUR 55,000 adds multi-lot RFQ, supplier scoring and real-time ERP connection.
Productivity gain: the -40% calculation
Manual processing of a supplier order (entry, follow-up, reconciliation) takes time. Here is the estimated impact on a base of 600 orders/month.
| Metric | Before (manual) | After (extranet) |
|---|---|---|
| Average time per order | 22 min | 13 min |
| Hours/month (600 orders) | 220 h | 130 h |
| Entry errors | 4% | 1% |
| Average supplier ack delay | 2.5 days | 0.5 day |
| Monthly processing cost (EUR 35/h) | EUR 7,700 | EUR 4,550 |
| Monthly saving | - | EUR 3,150 |
The 90 hours saved per month match the -40% processing-time target, an estimated saving of EUR 3,150/month.
Mini case study
Thomas is procurement director at a 140-employee component maker in an industrial zone in Amsterdam. He handles around 600 supplier orders a month with two full-time buyers. He invests EUR 42,000 in an extranet with RFQ and a connection to his Sage ERP.
With EUR 3,150 in monthly savings, or EUR 37,800/year, the extranet pays back in about 13 months. Bonus: supplier acknowledgement delay drops from 2.5 to 0.5 day, reducing component shortages on the production line.

FAQ
How long to deploy a supplier extranet?
Between 16 and 20 weeks in 2026, with a large share dedicated to ERP connection and integration testing. Without RFQ or ERP, a core can ship in 12 weeks.
Is ERP connection essential?
Not mandatory, but it is what removes double entry. At EUR 10,000 it is often the best-ROI item, especially above 300 orders/month.
Is the RFQ module worth its EUR 8,000?
Yes if you run regular consultations: it structures responses, enables objective comparison and keeps history. Buyers estimate 3 to 8% savings on negotiated prices.
How do you onboard suppliers?
Simple interface, pre-created accounts, notifications and a short training session. Usually 80% of active suppliers are operational within a month.
Can we start small then expand?
Yes: many manufacturers launch a EUR 25,000 core (accounts + orders + documents) then add RFQ and ERP in phase 2 based on measured ROI.
