The verdict in three sentences
In B2B, the right payment method is not the cheapest per unit but the one that balances fees, cash flow and unpaid-invoice risk. In 2026, a mix of card + SEPA transfer + deferred payment covers most cases for an SME. The key is to route large amounts to transfer (near-free) and secure deferred payment with credit insurance or factoring.
B2B payment methods compared
Each channel has its own cost and delay logic. The table summarizes the 2026 order of magnitude.
| Method | 2026 fees | Settlement delay | Unpaid risk |
|---|---|---|---|
| Bank card | 1.4 - 2.9 % + 0.25 EUR | 2 - 7 days | Low (3DS2) |
| SEPA transfer | 0 - 1 EUR fixed | 1 - 2 days | None (paid upfront) |
| SEPA direct debit | 0.20 - 0.50 EUR | 2 - 5 days | Medium (reversible) |
| Deferred payment 30-60 d | 1.5 - 3.5 % (if financed) | 30 - 60 days | High without cover |
| Wallet / Apple Pay | 1.4 - 2.5 % + 0.25 EUR | 2 - 7 days | Low |
For an average B2B basket of EUR 800, card costs about EUR 14.65 in fees versus under EUR 1 by transfer: at volume, the gap weighs heavily.
Full cost and unpaid-invoice handling
The visible fee is not the whole story. Deferred payment, in high demand in B2B, exposes you to unpaid-invoice risk that must be covered. Here is the 2026 impact.
| Scenario | 2026 cost / risk | Cash-flow impact |
|---|---|---|
| 100 % card | 1.4 - 2.9 % fees | Fast settlement |
| 100 % transfer | Near-free | Fast settlement |
| 30-day payment, no cover | 0.8 - 2 % unpaid observed | -30 days of cash |
| 30-day + credit insurance | 0.3 - 0.8 % premium | Risk covered |
| Factoring | 0.8 - 2.5 % + commission | Immediate settlement |
A savvy CFO reserves card for small amounts and new clients, transfer for reliable large accounts, and secures deferred payment with credit insurance.

Mini case study
Sophie, CFO of a food wholesaler in Nantes, does EUR 1.2M in online sales, average basket EUR 950. At 100 % card and 1.9 %, her fees reach EUR 22,800/year. By routing 60 % of revenue (recurring large accounts) to SEPA transfer, fees drop to 1.2M x 40 % x 1.9 % = EUR 9,120/year, saving EUR 13,680 annually. The cost of transfer integration and automatic reconciliation (EUR 7,000) is amortized in 6 months.
FAQ
Which payment method should B2B favor? SEPA transfer for large amounts (near-free, fast), card for small baskets and new clients (secured by 3DS2). The mix always beats all-card on fees.
Is deferred payment risky? Yes without cover: 0.8 to 2 % unpaid observed in 2026. Secure it with credit insurance (0.3-0.8 % premium) or factoring to transfer risk and recover cash flow.
How much does transfer reconciliation cost? Automation (matching invoice/transfer) represents EUR 3,000 to 8,000 in integration. It avoids hours of manual entry and secures unpaid-invoice tracking.
Can we offer several methods without blowing up costs? Yes: a modern PSP aggregates card, wallet and transfer in one funnel. The multi-method integration premium is EUR 2,000 to 5,000 over a single-card solution.
How to cut fees as volume grows? By negotiating the card rate above EUR 500,000/year of volume and shifting large accounts to transfer. An SME that structures its mix typically saves 30 to 50 % of fees.
