The verdict in three sentences
A custom supplier extranet for a manufacturing SME is priced between 20,000 and 60,000 EUR excl. VAT in 2026, ERP integration included depending on complexity. The standard timeline is 4 to 6 months, with a typical gain of 50% off processing delays for orders and documents. For an SME with 40 to 150 active suppliers, the return on investment materializes in 12 to 20 months.
Functional scope of a purchasing extranet
A supplier extranet replaces email back-and-forth and shared spreadsheets. It structures the order, delivery and invoicing cycle. Here are the most requested functions in 2026 and their cost.
| Function | Indicative cost (EUR excl. VAT) | Timeline |
|---|---|---|
| Supplier portal + secure accounts | 5,000 - 9,000 | 4-6 weeks |
| Order placement and tracking | 5,000 - 11,000 | 5-7 weeks |
| Document upload (delivery notes, invoices, certificates) | 3,500 - 7,000 | 3-5 weeks |
| Delivery tracking and acknowledgements | 3,000 - 6,000 | 3-5 weeks |
| ERP integration (SAP, Sage, Odoo) | 6,000 - 15,000 | 6-8 weeks |
| Purchasing dashboard + alerts | 4,000 - 8,000 | 4-6 weeks |
| Tender / RFQ portal | 4,000 - 9,000 | 4-6 weeks |
A basic extranet (portal + orders + documents) starts around 20,000-28,000 EUR excl. VAT. A full platform with deep ERP integration and a tender module reaches 50,000-60,000 EUR excl. VAT.

Mini case study
Marc, purchasing director at a 90-employee manufacturing SME in Lyon, manages 120 active suppliers. He invests 42,000 EUR excl. VAT in an extranet with Sage ERP integration. The purchasing team (4 people) saves 6 hours per person per week, i.e. 24 weekly hours. At 40 EUR loaded hourly cost, that is 960 EUR per week, roughly 46,000 EUR per year. Adding the reduction in disputes (estimated at 15,000 EUR/year), the return on investment drops below 12 months.
FAQ
How long to connect our ERP? ERP integration represents 6 to 8 weeks and 6,000 to 15,000 EUR excl. VAT depending on the ERP and its API quality. SAP and Odoo are the most common; Sage 100 sometimes needs an intermediary connector.
Will suppliers actually use it? Adoption depends on simplicity. Guided onboarding and email notifications push usage to 80-90% within three months. Making invoice upload mandatory to get paid accelerates adoption.
Can we manage multiple sites or entities? Yes, a multi-site extranet is configured per entity with distinct rights. Expect 3,000 to 6,000 EUR excl. VAT more for multi-entity management.
What annual maintenance budget? In 2026, plan 15 to 20% of the initial cost, i.e. 4,000 to 12,000 EUR excl. VAT per year, covering hosting, support and minor upgrades.
Is it relevant with fewer than 30 suppliers? Yes if order volume is high. Break-even depends more on the number of transactions than on the number of suppliers; a 20,000 EUR excl. VAT scope still pays off in under 2 years.
