It's great to see you here, @malikden.

I can walk you through the steps to record the refund transaction in QuickBooks Online.

Since a sales receipt is like a cash transaction, you can record the reversal by writing a check or expense. This process will offset the income that was reversed by the system.

To record the refund for your customer:

1. Select + New.
2. Select Expense, Add expense or Check.
3. Pick the customer you want to refund from the Payee ▼ drop-down.
4. From the Payment account ▼ drop-down, select the bank account where you deposited the reversed payment.
5. Use the same item from the sales on the check.
6. Enter how much you want to refund in the Amount field.
7. Fill out the other fields as you see fit, then select Save and close.

Once done, go back to Banking page. You should be able to Match it with the expense on the Bank Feeds. If not, click that transaction row for refund receipt to find a match.

Once everything is done, you can edit or delete the recurring transaction with the updated credentials.

Here's how to edit an existing recurring template:

1. Select Settings ⚙️.
2. Under Lists, select Recurring Transactions.
3. Select the appropriate template, then select the Action column ▼ drop-down menu and choose Use or Delete.
