If you pay via SEPA Direct Debit, funds are debited from your account by an authorized third party (the creditor or merchant). You authorize the debit by signing a SEPA Direct Debit mandate, which allows the merchant to initiate withdrawals under agreed terms (e.g., subscriptions, invoices, or utility payments). The merchant submits the collection to their bank - > you are notified in the APP prior to the expected collection -> the amount is debited from your business account -> funds are credited to the merchant account.
