SEPA Direct Debit: the recurring-payment rail that quietly runs Europe

SEPA Direct Debit (SDD) is the standardised pull-payment system for the eurozone. Instead of you pushing money every month, you authorise a creditor to pull it from your account. Rent, electricity, Netflix, insurance premiums, loan repayments — a huge fraction of your monthly outflows probably runs on SDD.

Two flavours

SDD Core is the consumer version. You can dispute and reverse any Core direct debit for 8 weeks without giving a reason — strong consumer protection, which is why creditors sometimes take extra verification steps before enabling it. SDD B2B is the business version. No automatic refund right (companies are presumed to be sophisticated enough to challenge up-front). B2B settles faster.

The mandate

Before any direct debit can run, you give the creditor a mandate — written, electronic, or in some cases via your bank app. The mandate includes a unique mandate reference and the creditor identifier (also unique and shareable with other creditors to let them look up the mandate).

How the money actually moves

The creditor submits a collection file to their bank with a specific due date. Your bank receives the collection via SEPA, verifies the mandate reference, and debits your account on the due date. If the account has insufficient funds, the collection fails and the creditor gets a reject message.

How to reverse one

Your bank app usually has a "dispute direct debit" button or option. Click it within 8 weeks of the debit date; the funds are refunded to your account within 10 business days. The creditor is then notified and has to re-collect through other means or discuss with you.

Common pitfalls

Cancelling the mandate is a separate action from blocking a specific debit. Some banks let you set a per-creditor cap. Switching banks requires updating all your mandates — a chore the new bank often helps automate.
