The verdict in three sentences
For a manufacturer near Amsterdam that manages 300 suppliers by email, a custom supplier portal costs between EUR 30,000 and EUR 75,000 excl. VAT, depending on how deep the ERP integration goes. The main gain is freed procurement time, roughly 15 to 20%, plus fewer data entry errors and certificates that are always up to date. Plan for 14 weeks for a full version, with a useful first release by week 8.
What a supplier portal includes in 2026
A procurement portal is more than a file drop. It centralizes document exchange, sourcing events and supplier performance tracking. Here are the modules we price most often for an industrial SME or mid-cap, with 2026 orders of magnitude.
| Module | Function | Indicative price excl. VAT | Timeline |
|---|---|---|---|
| Supplier onboarding and profile | Registration, IBAN, chamber of commerce extract, contacts | EUR 5,000 to 9,000 | 2 weeks |
| Certificate upload and tracking | ISO 9001, compliance statements, expiry alerts | EUR 4,000 to 8,000 | 2 weeks |
| Online tenders (RFQ) | Specifications, bids, comparison grid | EUR 8,000 to 18,000 | 3 to 4 weeks |
| Purchase orders and acknowledgements | Confirmation, lead times, delivery gaps | EUR 5,000 to 12,000 | 2 to 3 weeks |
| ERP integration (SAP, Exact, Microsoft Dynamics) | Items, orders and invoices sync | EUR 6,000 to 20,000 | 3 to 4 weeks |
| Performance dashboard | Service rate, non-conformities, scoring | EUR 3,000 to 8,000 | 1 to 2 weeks |
A minimal scope (onboarding, certificates, orders) starts around EUR 30,000 excl. VAT. With tenders, two-way ERP integration and supplier scoring, budgets reach EUR 60,000 to 75,000 excl. VAT.
Custom build, procurement SaaS or status quo: the comparison
Supplier portal SaaS suites exist, but their pricing is designed for large accounts. The comparison below covers 5 years, for 300 suppliers and 6 buyers.
| Criterion | Email + Excel | Procurement SaaS | Custom portal |
|---|---|---|---|
| Upfront cost | EUR 0 | EUR 10,000 to 25,000 (configuration) | EUR 30,000 to 75,000 excl. VAT |
| Annual cost | Hidden time | EUR 18,000 to 45,000/year | EUR 4,000 to 9,000/year (maintenance, hosting) |
| 5-year cost | Not measured | EUR 100,000 to 250,000 | EUR 50,000 to 120,000 |
| ERP integration | None | Standard connectors, sometimes paid | Fitted to your ERP and rules |
| Supplier adoption | Familiar | Generic interface | Local-language interface, simplified flow |
| Data and code ownership | Yes | No | Yes |
SaaS remains relevant if you have no business specifics. As soon as your qualification rules, sector certificates (automotive, food, aerospace) or ERP go beyond the standard, custom becomes cheaper from year three.
The typical 14-week schedule
| Phase | Weeks | Deliverable |
|---|---|---|
| Scoping and procurement workshops | 1 to 2 | Flow mapping, priorities |
| Mockups and sign-off | 3 to 4 | Supplier and buyer journeys |
| Build, release 1 | 5 to 8 | Onboarding, certificates, pilot go-live |
| Build, release 2 | 9 to 12 | Tenders, orders, ERP connector |
| Testing and rollout | 13 to 14 | Onboarding 300 suppliers in waves |
The critical point is onboarding: plan a three-wave campaign (strategic, recurring, occasional suppliers) and a one-page guide.

FAQ
How much does a supplier portal cost for an industrial SME?
In 2026, budget EUR 30,000 excl. VAT for a basic scope and up to EUR 75,000 excl. VAT with tenders and full ERP integration. Maintenance then runs EUR 4,000 to 9,000 a year.
Will my suppliers actually use the portal?
Yes, if first registration takes under 10 minutes and email remains a notification channel. On our projects, 70 to 85% of active suppliers are registered after 3 months.
Can the portal connect to SAP or Exact?
Yes, through APIs, exchange files or dedicated connectors. This item represents EUR 6,000 to 20,000 excl. VAT depending on the number of synced flows.
Is the project GDPR compliant?
Supplier data is mostly company data, but named contacts fall under the GDPR. We plan EU hosting, access logging and defined retention periods.
Can we start with a pilot?
Yes, a release 1 limited to 30 strategic suppliers ships in 8 weeks for EUR 18,000 to 25,000 excl. VAT, then expands.
