The verdict in three sentences
A manufacturing supplier portal costs between 50 000 and 120 000 EUR in 2026, with the dominant line item being ERP integration (SAP/Sage) and EDI. The realistic timeline is 5 to 7 months. The ROI comes from cutting disputes and processing times by around 40 % (orders, delivery notes, invoices, non-conformities) and from more reliable data.
What the budget of a supplier portal covers
The estimate is driven by supplier onboarding, quality and the ERP/EDI connection.

|---|---|---|
| Onboarding & supplier accounts | Registration, documents, roles | 7 000 - 15 000 |
| Orders & acknowledgements | PO, confirmations, forecasts | 8 000 - 17 000 |
