The verdict in three sentences
A supplier portal to digitise tenders, orders and invoices costs between 30,000 and 75,000 EUR (excl. VAT) in 2026, delivered in 14 to 20 weeks. The structuring blocks are the approval workflow, order and invoice management and the ERP connector (6,000 to 14,000 EUR). The measurable gain: procurement processing time cut by around 40% and full traceability.
What a supplier portal funds
For a manufacturer, a supplier portal replaces emails and Excel files with structured flows: consultation, order, receipt, invoicing. The budget spreads across well-defined modules.
| Module | Cost 2026 (excl. VAT) | Benefit |
|---|---|---|
| Tenders / consultation | 6,000 - 13,000 EUR | Traceable competitive bidding |
| Order and invoice management | 7,000 - 15,000 EUR | Digitised purchase cycle |
| Approval workflow | 5,000 - 11,000 EUR | Hierarchical controls |
| ERP connector | 6,000 - 14,000 EUR | Stock, prices, accounting |
| Supplier area (docs, KYC) | 3,000 - 7,000 EUR | Up-to-date registry |
| Procurement reporting | 3,000 - 6,000 EUR | Spend steering |
2026 order of magnitude for a mid-sized manufacturer; the ERP connector often concentrates the technical complexity.
Total cost and maintenance
An ERP-connected supplier portal requires sustained maintenance, especially on data flows.
| Item | Cost 2026 | Frequency |
|---|---|---|
| Development | 30,000 - 75,000 EUR | one-off |
| ERP connector | 6,000 - 14,000 EUR | one-off |
| Hosting + database | 120 - 350 EUR | per month |
| Maintenance | 12% of budget | per year |
| Security audit | 2,000 - 5,000 EUR | per year |
| Encrypted backups | 40 - 90 EUR | per month |
Maintenance at 12% of the budget per year is essential: on a 60,000 EUR portal, budget ~7,200 EUR/year, mainly to keep the ERP connector current as the management system evolves.

Mini case study
Julien, procurement manager at a 220-employee manufacturer in Grenoble, processes about 900 supplier orders/month. Each order currently takes 22 minutes across price request, approval and entry, roughly 330 hours/month for his team.
He invests 62,000 EUR (portal + ERP connector) in a platform with approval workflow and invoice management. Processing time drops by 40%, or 132 hours saved per month for the procurement team. Valued at 42 EUR/h fully loaded, the saving reaches 66,528 EUR/year. With 7,440 EUR/year maintenance, the platform pays back in the first year, before counting fewer invoicing errors and supplier disputes.
FAQ
What is the difference between a supplier portal and an ERP purchasing module? The ERP module handles the internal side; the portal opens a secure interface to suppliers to answer consultations, confirm orders and upload invoices. The two complement each other via a connector.
Is the ERP connector mandatory? Strongly recommended: without it, prices, stock and order statuses stay in double entry. The connector (6,000 to 14,000 EUR) keeps data reliable in real time and removes accounting re-entry.
Can we manage a multi-level approval workflow? Yes: depending on the amount, an order can require a buyer's, then a manager's, then a director's approval. This workflow (5,000 to 11,000 EUR) secures spending commitments and speeds up the circuits.
How do we handle supplier compliance (KYC)? The portal centralises documents (registration, certificates, bank details) with expiry reminders, keeping the supplier registry up to date and easing audits.
How long to deploy? From 14 to 20 weeks: 3-4 weeks framing purchase flows, 8 to 12 of development including the connector, 3 to 4 of testing, supplier registry migration and training.
