If you need to return your customer’s payment, you can use refund receipts to record a refund for goods or services in QuickBooks Online, and there is no need to make changes on the invoice that you’ve created.
To record Refund receipts, here’s how.
- Go to the + New button.
- Select the Refund receipt.
- On the Customer ▼ dropdown, and then, select the customer you want to refund.
- On the Refund From ▼ dropdown, then select the bank you deposited the payment.
- Add all products or services the customer returned in the Product /Service column.
- Fill in the quantity, rate, amount, and other fields.
- Then, select Save and close.
