Start with the evidence
Gather the original receipt and refund evidence. Check whether the refund covers the whole purchase or only particular items, and keep currency and reference details visible.
Work through the example
A USD60 purchase has a confirmed USD15 refund for one returned item. The net example amount is USD45, but the two source records should remain traceable rather than being replaced by an unexplained USD45 receipt.
Make the next step clear
Record the relationship and any remaining question about timing or treatment. A promised refund is different from a confirmed refund record, so preserve that distinction in the status.
Keep the source context
These guides concern the evidence behind a business record. A receipt, a reimbursement request and a bank movement may describe related parts of one event, but they are not interchangeable documents. Keep each source and its role visible.
