SEPA Direct Debit Core (SDD Core) and SEPA Direct Debit B2B (SDD B2B) both enable regular payments for recurring obligations such as bills, rent, and subscriptions.

SDD Core is intended to enable all direct debit transactions, while SDD B2B is solely for recurring transactions between businesses or organisations. Functionally, both payment methods are similar but with key distinctions on the direct debit mandate management and refunds timelines.

In this article we outline how the SEPA direct debit payment schemes work, and how SDD B2B provides additional protections for businesses.

A SEPA direct debit core (shortened to SDD core) is a payment pulled and debited from the debtor’s account and credited to the creditor’s account. SEPA direct debits are commonly used for recurring payments such as rent, utilities, software subscriptions, loan repayments, etc.

A SEPA direct debit core payment requires a mandate from the debtor to the creditor, which authorises the creditor to debit the debtor’s account under certain pre-agreed conditions. The mandate is identified by a unique mandate reference (or UMR). The creditor is identified by a creditor identifier, which is usually assigned by the national bank of the country of the creditor.

The payment must be initiated between two weeks and two business days before its due date. It can be rejected by the debtor’s bank until five days after its due date, for instance if the account has been closed. The debtor needs to be notified two weeks in advance of the settlement date unless the debtor explicitly waives the notification.

A SEPA direct debit can be refunded up to eight weeks after execution. In that period, a refund can be requested even if there was a valid mandate and even if the payment had been authorised. A refund can be then requested for up to 13 months after execution if there was no valid mandate, or if the payment was not authorised.
