SEPA Direct Debit
SEPA Direct Debit (SDD) is the pan-European bank debit scheme governed by the European Payments Council, enabling merchants to pull euro-denominated payments directly from a customer’s bank account across 36 SEPA countries, covering over 520 million people. It operates under two distinct schemes: SDD Core, which covers consumer payers and is mandatory for PSPs offering euro direct debit, and SDD B2B, which is designed exclusively for business-to-business payment flows and offers the merchant stronger protection, including the removal of the consumer’s unconditional refund right.
The mechanics are straightforward: the customer signs a mandate authorising the merchant to collect payments from their bank account. The merchant then submits debit instructions through their PSP referencing that mandate. For recurring billing, the mandate is signed once and remains in place for the full billing relationship, which significantly reduces friction for subsequent collections compared to card-based recurring flows that require re-authentication or are vulnerable to card expiry.
SDD is one of the most cost-efficient collection methods available to European merchants. Per-transaction fees are typically lower than card processing, there are no interchange fees, and bank account details do not expire the way card credentials do, reducing involuntary churn in subscription and recurring billing models. It is particularly well established for recurring use cases in Germany and the Netherlands, where consumer comfort with bank debit is high.
There are operational considerations worth managing carefully. Under SDD Core, consumers have an unconditional right to a refund for up to eight weeks after the debit date, and in cases of unauthorised mandates up to thirteen months. This introduces a returns exposure that needs to be factored into risk and reconciliation processes. Mandate management, including storage, reference tracking, and amendment handling, adds operational overhead that varies in complexity depending on how your PSP handles it. The quality of mandate management tooling differs meaningfully between providers, so it is worth evaluating before committing to a PSP for SDD-heavy use cases.
SCA under PSD2 applies to the initial mandate setup for consumer SDD flows. Subsequent collections on the same mandate for the same merchant are typically exempt as merchant-initiated transactions, provided the initial authentication was properly handled by your payment provider. How well your PSP implements this exemption logic has a direct impact on approval rates and checkout friction.
PSP support for SEPA Direct Debit is broad. Adyen, Stripe, Mollie, Buckaroo, and most major European providers offer it natively. The SDD B2B scheme has more limited PSP coverage, so if B2B debit collection is a requirement, confirming explicit B2B scheme support with your provider is a necessary step.
