The verdict in three sentences
For an SME, the right 2026 mix combines card (Stripe 1.4% + EUR 0.25 on EU cards) and SEPA transfer (EUR 0.25 to 0.80/transaction) to crush fees on large amounts. Integrating a gateway costs EUR 3,500 to 9,000 depending on the number of payment methods and compliance. The key is routing each order to the cheapest method: card for small baskets, transfer for large ones.
Fee comparison by payment method
Fees vary sharply by channel. 2026 order of magnitude for an SME.
| Payment method | 2026 fees | Best for |
|---|---|---|
| EU card (Stripe) | 1.4% + EUR 0.25 | Baskets < EUR 300 |
| Non-EU card | 2.9% + EUR 0.25 | International |
| SEPA transfer | EUR 0.25 - 0.80 | Baskets > EUR 500 |
| SEPA direct debit | 0.20% + EUR 0.20 | Subscriptions |
| Alternative PSP | 1.1% + EUR 0.20 | High volume |
| Wallet (Apple/Google Pay) | 1.4% + EUR 0.25 | Mobile |
Monthly cost by volume
The mix depends on volume and average basket. 2026 simulation with a EUR 250 average basket, assuming 70% card / 30% transfer.
| Monthly volume | 100% card (Stripe) | Card + transfer mix | Saving/month |
|---|---|---|---|
| EUR 10,000 | EUR 149 | EUR 116 | EUR 33 |
| EUR 50,000 | EUR 745 | EUR 566 | EUR 179 |
| EUR 100,000 | EUR 1,490 | EUR 1,118 | EUR 372 |
| EUR 200,000 | EUR 2,980 | EUR 2,220 | EUR 760 |
At EUR 200,000/month, routing large baskets to transfer saves about EUR 9,120/year, with no change to the customer experience.
Mini case study
Celine, CFO of a trading SME in London, collected 100% by card on EUR 120,000/month, i.e. EUR 1,788 in monthly fees. By adding SEPA transfer for orders above EUR 500 (35% of volume), fees drop to EUR 1,290/month: a saving of EUR 498/month, or EUR 5,976/year. The integration at EUR 6,500, including 3-D Secure 2 and PCI-DSS SAQ-A compliance, pays back in 13 months.

What card fees should we expect in 2026?

What does PCI-DSS compliance involve?
Using a hosted gateway (Stripe, PSP), you fall under SAQ-A, the lightest level: you never store card data. Integration includes 3-D Secure 2, required for strong authentication.
How much does gateway integration cost?
Between EUR 3,500 and 9,000 depending on the number of payment methods, smart routing and reconciliation webhooks. Expect 1 to 3 weeks of development.
Where to host to stay compliant?
Hosting on OVH or Scaleway in the EU ensures data localisation and GDPR compliance, for EUR 100 to 400/month depending on traffic. Payment logs stay in the EU.
