Let me help complete the partial refund from a credit card transaction.
If the item’s quantity on the receipt is 2 or more, or you have multiple items, you can process a refund for only one quantity or one item. However, if your receipt has one item with one quantity, you’ll need to reverse the entire transaction. Then reprocess the receipt and deduct the refund amount.
If you’re processing credit card transaction through Intuit merchant services, you’ll need to sign out from merchant services before you process refund in Point of Sale.
Please let me know if there’s anything else I can help you with. I’ll always be here to help.
