The verdict in three sentences
Integrating online payments for an SME in Amsterdam costs 4,000 to 12,000 EUR in 2026, over a 2 to 5 week timeline. On top of this integration cost come fees of 1.4 to 2.9% + 0.25 EUR per transaction depending on provider and card type. The right choice depends mainly on your monthly volume and your need to reconcile with accounting.
What the integration covers
Development is not just a "pay" button. You need 3D Secure 2 (PSD2 strong authentication), SEPA and bank-transfer payments, confirmation webhooks, refunds, and reconciliation with the ERP or accounting tool.
| Item | 2026 range (EUR) | Timeline |
|---|---|---|
| PSP integration + checkout | 2,000 - 5,000 | 1-2 wks |
| 3DS2 + failure handling | 800 - 2,000 | 3-5 d |
| Webhooks + order status | 700 - 1,800 | 3-5 d |
| SEPA / transfer / IBAN | 900 - 2,500 | 1 wk |
| Accounting reconciliation | 1,200 - 3,500 | 1-2 wks |
| Integration total | 4,000 - 12,000 | 2-5 wks |
PCI-DSS is delegated to the PSP (Stripe, Adyen, local PSP): you never store card numbers, which sharply reduces your compliance burden.
Stripe vs. local PSP vs. bank solution
Total one-year cost depends less on integration than on the fees applied to your volume.
| Criterion | Stripe / Adyen | Local PSP | Bank solution |
|---|---|---|---|
| Card fee | 1.4 - 2.9% + 0.25 EUR | 1.2 - 2.2% | 0.9 - 1.8% + fee |
| Setup | 4,000 - 8,000 EUR | 5,000 - 10,000 EUR | 6,000 - 12,000 EUR |
| Payout delay | D+2 to D+7 | D+1 to D+3 | D+1 to D+2 |
| SEPA / transfer | Yes | Yes | Native |
| Cost at 5,000 EUR/mo | ~110 EUR/mo | ~90 EUR/mo | ~70 EUR + fee |
| Cost at 50,000 EUR/mo | ~1,100 EUR/mo | ~850 EUR/mo | ~650 EUR + fee |
Below 10,000 EUR/month in volume, Stripe is often the most cost-effective once integration is amortised; above that, a negotiated bank solution becomes competitive.
Mini case study
Sophie, owner of a trading SME in Amsterdam, currently takes cheques and manual transfers, with a 12-day average collection delay. She invests 7,500 EUR in a Stripe integration with automated reconciliation. On a volume of 30,000 EUR/month, fees reach about 660 EUR/month, but she saves 6 hours a week of data entry and cuts collection time to 2 days. The cash-flow and admin-time gain is estimated at 18,000 EUR/year, a payback under 6 months.
