The verdict in three sentences
For a mid-size company buying EUR 40M a year from 900 suppliers, running sourcing events by email costs far more than a platform. A custom e-procurement solution costs EUR 50,000 to 90,000 excl. VAT and pays off by year two against SaaS licences of EUR 30,000 to 80,000 a year. With a realistic target of 3% savings on part of the spend, payback is measured in months, provided the ERP connector is scoped properly.
What a custom procurement platform costs in 2026
The budget depends mainly on the number of modules and on the complexity of the integration with your ERP (Exact, AFAS, SAP Business One or Microsoft Dynamics, all common in the Netherlands). Here is a 2026 order of magnitude for a company with 250 to 1,500 employees.
| Module | Scope | 2026 budget excl. VAT | Lead time |
|---|---|---|---|
| Supplier onboarding | Supplier record, KvK extract, insurance, scoring | EUR 8,000 to 14,000 | 3 to 4 weeks |
| RFQs and tenders | Specifications, sending, bid submission, reminders | EUR 12,000 to 20,000 | 4 to 6 weeks |
| Bid comparison | Multi-criteria grid, price/lead time/quality weighting, history | EUR 7,000 to 12,000 | 2 to 3 weeks |
| Approval workflow | Thresholds by amount, delegations, sign-off, audit trail | EUR 6,000 to 11,000 | 2 to 3 weeks |
| ERP connector | Sync of suppliers, purchase orders, goods receipts | EUR 9,000 to 20,000 | 3 to 6 weeks |
| Procurement dashboards | Spend by category, competition rate, savings | EUR 5,000 to 9,000 | 2 weeks |
| Testing, training, rollout | Tests, training for buyers and requesters | EUR 3,000 to 6,000 | 2 weeks |
A full scope therefore lands between EUR 50,000 and 90,000 excl. VAT, delivered in 4 to 6 months in successive releases. Ongoing maintenance usually represents 12 to 18% of the initial budget per year, i.e. EUR 7,000 to 14,000.
Custom build or SaaS licence: the five-year comparison
Market suites (Ivalua, Coupa, Jaggaer, Oalia, Per Angusta) are powerful but billed per user or per spend volume. For a mid-size company, the comparison plays out over time.
| Criterion | Custom platform | Procurement SaaS suite |
|---|---|---|
| Initial cost | EUR 50,000 to 90,000 excl. VAT | EUR 15,000 to 40,000 (configuration) |
| Annual cost | EUR 7,000 to 14,000 (maintenance, hosting) | EUR 30,000 to 80,000 (licences) |
| Cumulative 5-year cost | EUR 85,000 to 160,000 | EUR 165,000 to 440,000 |
| Fit with your processes | Complete | Partial, depends on vendor roadmap |
| ERP connector | Built for your ERP | Standard, often charged extra |
| Ownership of data and code | You | Vendor, exit terms to negotiate |
| Time to go live | 4 to 6 months | 3 to 9 months depending on integration |
SaaS remains relevant for a multi-country group with buyers in ten subsidiaries. For a regional mid-size company with a procurement team of 4 to 10 people, custom usually costs two to three times less over five years.
Where the 3 to 5% savings come from
Savings do not appear by magic: they come from systematic competitive bidding and visibility on spend.
| Lever | Email-based process | With the platform | Estimated gain |
|---|---|---|---|
| Share of spend put out to competition | 35 to 45% | 70 to 85% | 2 to 4% on the scope concerned |
| Bids per sourcing event | 1.8 on average | 3 to 4 | Stronger price tension |
| Off-contract (maverick) buying | 15 to 25% | 5 to 8% | 1 to 2% |
| Time per sourcing event | 6 to 8 h | 2 to 3 h | Buyers refocused on negotiation |
| Disputes over terms | Frequent | Full traceability | Fewer penalties and delays |
These figures are 2026 orders of magnitude observed in industrial and distribution companies. They assume management enforces the platform above a threshold, for example EUR 5,000 excl. VAT.

Pieter, head of procurement at a mid-size engineering company in Amsterdam, manages EUR 40M of spend and 900 suppliers with 6 buyers. He picks a EUR 72,000 scope (onboarding, RFQs, comparison, approval, Exact connector) plus EUR 10,000 of annual maintenance.
He first targets spend outside indexed raw materials, i.e. EUR 14M. A prudent 3% saving on that scope represents EUR 420,000 a year. Even with only 1% in year one (EUR 140,000), the project pays back in about 7 months. Against a SaaS licence at EUR 55,000 a year, he also saves around EUR 190,000 over five years in software costs.
