The verdict in three sentences
For a B2B webshop whose average basket exceeds EUR 500, instant SEPA transfer via payment initiation costs 20 to 100 times less than cards, with funds credited in under 10 seconds. Since the EU instant payments regulation, eurozone banks must offer instant transfers at the same price as a standard transfer, which removed the last barrier for buyers. With an integration budget of EUR 4,000 to 12,000 excl. VAT, the investment usually pays back in one to four months.
What changed in 2025 and 2026
Regulation (EU) 2024/886 requires eurozone payment service providers to receive instant transfers since January 2025 and to send them since October 2025, priced identically to standard transfers and with a payee verification check (name and IBAN) before approval. In practice, your buyer, whether an SME accountant or a group purchaser, can pay a EUR 1,500 invoice from their banking app in seconds at no extra cost.
On the webshop side, the flow relies on payment initiation (PIS, defined by PSD2): the customer picks their bank at checkout, authenticates in their banking app and approves a prefilled transfer (amount, IBAN, order reference). No IBAN to copy, no wrong reference.
| Payment method | Cost on a EUR 1,500 basket | Settlement time | Non-payment risk | Reconciliation |
|---|---|---|---|---|
| European consumer card (online contract) | EUR 22.50 to 37.50 (1.5 to 2.5%) | D+1 to D+3 | Chargebacks up to 13 months | Semi-automatic |
| Commercial / corporate card | EUR 30 to 45 (2 to 3%) | D+1 to D+3 | Chargebacks possible | Semi-automatic |
| Manual standard SEPA transfer | EUR 0 to 0.50 | D+1, no date guarantee | Low, but frequent delays | Manual, wrong references |
| Instant transfer via payment initiation | EUR 0.20 to 1 per payment | Under 10 seconds | Irrevocable once sent | Automatic via unique reference |
| SEPA B2B direct debit | EUR 0.30 to 0.80 | D+2 to D+5 | Rejection if no mandate | Automatic |
| 30-day terms via B2B BNPL | 1.5 to 4% of basket | D+1 (funded by provider) | Carried by provider | Automatic |
What integration costs
Three options coexist in 2026. The fastest is enabling payment initiation from your existing payment provider, if it supports it. The most common goes through a specialised open banking aggregator connected to 2,000 to 3,000 European banks, billed per payment. The heaviest, for large volumes, relies on a licence or direct access through your bank.
| Item | Existing provider option | Open banking aggregator option | Direct bank integration option |
|---|---|---|---|
| Checkout integration | EUR 1,500 to 3,000 excl. VAT | EUR 4,000 to 8,000 excl. VAT | EUR 15,000 to 30,000 excl. VAT |
| Automatic ERP / invoicing reconciliation | EUR 1,500 to 3,000 excl. VAT | EUR 2,500 to 4,000 excl. VAT | EUR 5,000 to 10,000 excl. VAT |
| Fee per payment | EUR 0.50 to 1 | EUR 0.20 to 0.60 | EUR 0.05 to 0.20 |
| Monthly subscription | EUR 0 to 50 | EUR 0 to 300 | Per bank agreement |
| Time to production | 2 to 3 weeks | 4 to 6 weeks | 3 to 6 months |
| Relevant volume | Under 500 orders/month | 200 to 10,000 orders/month | Over 10,000 orders/month |
The most underestimated item is reconciliation. Each payment carries a unique reference generated by the shop; the confirmation webhook marks the order as paid, triggers fulfilment and matches the invoice in the accounting tool. That is where the CFO wins back the most time.
Annual savings by volume
Assumptions: EUR 1,500 average basket, 60% of customers switch from card to instant transfer, average card fees of 1.9%, instant transfer fee of EUR 0.50 per payment.
| Orders per month | Current card fees / year | Fees after 60% switch / year | Annual savings | Payback on a EUR 8,000 integration |
|---|---|---|---|---|
| 100 | EUR 34,200 | EUR 14,040 | EUR 20,160 | 4.8 months |
| 250 | EUR 85,500 | EUR 35,100 | EUR 50,400 | 1.9 months |
| 500 | EUR 171,000 | EUR 70,200 | EUR 100,800 | 1 month |
| 1,000 | EUR 342,000 | EUR 140,400 | EUR 201,600 | 2 weeks |
| 2,000 | EUR 684,000 | EUR 280,800 | EUR 403,200 | 1 week |
These are 2026 orders of magnitude: they depend on your card contract, the share of commercial cards (more expensive) and the actual switch rate, which mostly depends on how prominently the method is shown at checkout. A 1% discount for instant payment clearly speeds up adoption while staying profitable.

Mini case study
Claire, CFO of an industrial supplies distributor in Lyon, processes 400 orders a month with a EUR 1,500 average basket, i.e. EUR 600,000 monthly. Her card fees at 1.9% amount to EUR 11,400 a month. After integrating an aggregator (EUR 6,500 excl. VAT checkout + EUR 3,000 excl. VAT reconciliation), 55% of orders move to instant transfer: 220 payments at EUR 0.50, i.e. EUR 110, and card fees drop to EUR 5,130. Monthly savings: EUR 6,160, or EUR 73,900 a year, for a EUR 9,500 investment repaid in seven weeks. Her accounting team also saves around 25 hours a month of manual matching.
FAQ
Is instant transfer really free for the buyer?
Since 2025 their bank must charge the same price as a standard SEPA transfer, which is free in most business plans. The few accounts that charge for transfers pay around EUR 0.20 to 1 per transaction.
Is there an amount ceiling?
The SEPA Instant scheme has had no technical cap since 2023, but each bank can set default limits, often EUR 15,000 to 100,000 per day for business accounts. Customers can usually raise them in their banking app.
What happens with a dispute or a return?
The transfer is irrevocable: refunds are made through a return transfer you initiate, which removes card chargebacks. Set up a 48-hour refund procedure to reassure buyers.
Should we drop cards?
No: keep them for small baskets and new customers. Aim for 50 to 70% instant payments on baskets above EUR 500, which captures most of the savings.
How long to go live?
Allow 4 to 6 weeks with an aggregator, including reconciliation testing. Bank approval and PSD2 compliance are handled by the licensed provider.
