Mandate management is the set of processes and systems a business or bank uses to handle payment mandates throughout their life: capturing the payer's authority, giving it a unique reference, storing evidence of consent, applying amendments, and recording cancellations and expiry. It is essential for any organisation that collects money by direct debit, through SEPA Direct Debit or ACH debits, or through open banking variable recurring payments. Good mandate management lets the collector prove each payment was authorised if a payer disputes it, stops collections promptly after cancellation, and keeps mandate data in line with scheme rules, such as sending advance notice before a collection or treating long-unused mandates as expired. Many payment service providers and billing platforms offer mandate management as part of their collection service, while banks also track mandates to handle refund claims and direct debit returns.
