The verdict in three sentences
For a B2B SME invoicing 400 customers a month, bank transfer looks free but is expensive in cash terms with an average DSO of 45 days. SEPA Direct Debit via GoCardless (1% + EUR 0.20, capped) is usually the best trade-off for subscriptions and recurring billing, while Stripe (1.5% + EUR 0.25 per EU card) suits small one-off invoices. The real saving comes from automatic reconciliation with your accounting software, best built alongside your 2026 e-invoicing compliance.
The hidden cost of bank transfers
Bank transfers cost nothing per transaction, but the customer decides when to pay. The result: reminders, partial payments without references and manual reconciliation that often takes an accountant several days a month. Across 400 monthly invoices, every day of DSO saved frees up cash.
| Collection method (2026 estimate) | Fee per transaction | Average DSO | Reconciliation | Failure or default rate |
|---|---|---|---|---|
| Standard bank transfer | EUR 0 | 40 to 55 days | Manual | Frequent delays |
| SEPA Instant transfer | EUR 0 to 1 | 30 to 45 days | Semi-automatic | Frequent delays |
| Stripe EU card | 1.5% + EUR 0.25 | 1 to 3 days | Automatic | 1 to 3% |
| Stripe SEPA Direct Debit | EUR 0.35 per transaction | 5 to 8 days | Automatic | 1 to 2% |
| GoCardless SEPA Direct Debit | 1% + EUR 0.20, capped | 3 to 6 days | Automatic | 0.5 to 1.5% |
| Stripe payment link on invoice | 1.5% + EUR 0.25 (card) | 5 to 15 days | Automatic | Low |
Pricing varies with volume and negotiation: a CFO collecting more than EUR 100,000 a month can obtain custom terms from both providers.
Simulation on 400 invoices a month
Take an average invoice of EUR 850 excl. VAT, about EUR 340,000 collected per month.
| Scenario | Estimated monthly fees | DSO | Cash tied up | Reconciliation time |
|---|---|---|---|---|
| 100% bank transfer | EUR 0 | 45 days | About EUR 510,000 | 3 to 4 days/month |
| 100% Stripe card | About EUR 5,200 | 2 days | About EUR 23,000 | A few hours |
| 100% GoCardless (EUR 4 cap per transaction) | About EUR 1,600 | 5 days | About EUR 57,000 | A few hours |
| Mix: 70% GoCardless, 20% card, 10% transfer | About EUR 2,200 | 9 days | About EUR 100,000 | Under one day |
At a 5% annual cost of financing, freeing EUR 400,000 of cash is worth about EUR 20,000 a year, before counting accounting time saved. The direct debit plus card mix pays off within the first months.
Automatic reconciliation and 2026 e-invoicing
From September 2026, all French businesses must be able to receive e-invoices through an accredited platform, with large and mid-sized companies also issuing them; SMEs follow in September 2027, and other EU countries are rolling out similar mandates under ViDA. It is the right moment to connect the full chain: invoice issued, payment link or debit mandate, collection, then automatic matching in your accounting tool (Pennylane, Exact, Xero, Sage). Stripe and GoCardless return each payment with the invoice reference, removing most manual reconciliation. A custom integration usually costs EUR 4,000 to 15,000 depending on your ERP and e-invoicing platform.

Isabelle, CFO of an industrial maintenance services SME near Nantes, invoices 400 customers a month for EUR 340,000. She moves 70% of recurring customers to GoCardless direct debit and adds a card payment link to the other invoices. Fees: about EUR 2,200 a month, EUR 26,400 a year. Gains: DSO from 45 to 9 days, EUR 410,000 of cash freed (about EUR 20,500 a year in avoided financing costs) and 3 fewer reconciliation days a month (about EUR 9,000 a year). With an EUR 8,000 integration, the net balance turns positive in year two, and immediately if the SME funds working capital through factoring.
FAQ
What are Stripe's fees for a B2B SME in 2026?
About 1.5% + EUR 0.25 per standard European card, and EUR 0.35 per SEPA Direct Debit. Business and non-EU cards cost more, up to 2.5% to 3.25%.
Is GoCardless cheaper than Stripe?
For larger invoices, often yes: 1% + EUR 0.20 with a per-transaction cap. On an EUR 850 invoice, GoCardless costs around EUR 4, versus more than EUR 12 by card through Stripe.
Is SEPA Direct Debit suitable for B2B?
Yes, especially the SEPA B2B scheme for recurring contracts. Failure rates stay low, around 0.5 to 1.5%, and collection time drops to 3 to 6 days.
Should we drop bank transfers?
No, keep them for key accounts that require them. A realistic goal is to move 60 to 80% of collections to direct debit or card.
How does this relate to 2026 e-invoicing?
The French reform requires receiving e-invoices from September 2026. Use the compliance project to connect payments and matching, for EUR 4,000 to 15,000 of integration work.
