Refund

A refund returns some or all of a previous payment to the payer. It is a money movement rather than merely an accounting adjustment: issuing a credit note does not automatically execute it.[2] A partial refund returns less than the remaining refundable amount.[1]

Link reason, amount and payment reference to the original order. For partial returns, check earlier refunds. Distinguish a request, processing and confirmation; internal approval does not mean the customer already sees the money. If a payment dispute exists, also prevent reimbursing the same amount twice.
