The verdict in three sentences
A custom supplier extranet for a manufacturing SME costs between 25,000 and 55,000 EUR in 2026, ERP integration included. It replaces email/Excel chaos with a single approval workflow, a multi-supplier portal and real-time order tracking. The ROI reads in hours: 10 to 20 hours a week recovered in procurement and accounting, a payback in 12 to 24 months.
What a supplier extranet funds
The extranet centralises orders, acknowledgements, documents (certificates, delivery notes, invoices) and approval cycles. Here is a median 2026 budget.
| Line item | 2026 range (EUR) | Note |
|---|---|---|
| Discovery & process mapping | 3,500 - 6,500 | Procurement, supply, accounting workshops |
| Multi-supplier portal | 5,000 - 11,000 | Accounts, roles, invites |
| Order management & tracking | 5,000 - 12,000 | Statuses, acknowledgements, reminders |
| Approval workflow | 3,500 - 8,000 | Rules, thresholds, delegation |
| ERP integration | 5,000 - 12,000 | Sage, SAP B1, Dynamics |
| Documents & archiving | 2,000 - 5,000 | DMS, versions, traceability |
| QA & rollout | 3,000 - 6,000 | Testing, training, GDPR |
| Total | 25,000 - 55,000 | By scope |
Build vs the email/Excel status quo
The status quo looks free but is expensive in time, errors and disputes. Here is a one-year comparison for a 4-person procurement team.
| Criterion | Email/Excel status quo | Custom extranet |
|---|---|---|
| Annual software cost | ~0 EUR | 3,000 - 5,000 EUR |
| Hours lost/week | 10 - 20 h | 2 - 4 h |
| Order errors | Frequent | Rare |
| Document traceability | Weak | Full |
| Approval delay | 2 - 5 days | A few hours |
| Real-time visibility | No | Yes |
| Upfront cost | 0 EUR | 25,000 - 55,000 EUR |

Sarah, head of procurement at an 80-person SME in Berlin, manages 45 recurring suppliers. Her team loses about 15 hours a week to data entry, chasing and reconciliation, some 720 hours a year. At a loaded cost of 42 EUR/hour, that is 30,240 EUR annually. With an extranet at 42,000 EUR cutting that time by 75%, she saves about 22,680 EUR a year. Payback under 24 months, before counting fewer supplier disputes and stockouts.
FAQ
Must the extranet connect to our ERP? Yes, it is the line that creates most value. Budget 5,000 to 12,000 EUR depending on the ERP (Sage, SAP Business One, Dynamics) and API richness. Without it, gains halve.
How long to deploy? Expect 12 to 18 weeks in 2026. A first batch (portal, orders, notifications) ships in 8 to 10 weeks, with advanced workflow and ERP following.
Will our suppliers adopt it? Yes if onboarding is simple: email invite, no install, clean interface. Plan hands-on support for the first 10 suppliers to remove friction.
What is a realistic time saving? Order of magnitude 2026: 10 to 20 hours a week for a 3-5 person team, concentrated on data entry, chasing and document reconciliation.
Can we start small? Yes. A 20,000-25,000 EUR MVP (portal + orders + documents) validates usage before adding advanced workflow and integrations. It is often the best entry point.
