I'm here to guide you on what you can do so customer balance will show the correct amount instead of negative number, AjayK76.

There are several ways on how you can give refunds in QuickBooks Online (QBO). For credit card refunds, they have a few requirements. I've provided the list below:

• Credit card refunds can only go back to the original card used for the purchase. You may need to contact your customer to get this info.
• You can refund up to the amount of the original sale, but not more.
• You can only issue credit card refunds within 90 days of the sale.

You'll want to refund credit card payments by following the steps below:

1. Select + New.
2. Select Refund receipt.
3. Select the customer you want to refund from the Customer ▼ dropdown.
4. Enter the details in the fields using the same info from the original sale. To credit back their credit card, in Payment method, select Credit card. To credit back their bank account, in Payment method, select Direct Debit.
5. In Refund From, select the account you wish to refund the customer from.
6. Select Save and close.

However, if you want to refund a customer who paid you with a credit card right from the sales receipt, invoice or associated payment, I've provided the steps below:

1. Go to Bookkeeping then Transactions then All Sales (Take me there), or go to Sales then select All Sales (Take me there).
2. Find and select the sales receipt, invoice, or payment.
3. In the footer, select More, then Refund.
4. A refund receipt opens with all of the information from the customer form automatically filled in, such as payment method, the refunding account, and customer details. Verify that everything looks correct.
5. Optionally, you can give a partial refund. Just adjust the items or amount you want to refund.
6. Select Save and close.
