Customer credit memos are non-posting transactions, as they don't affect the actual accounts in your books, Leanne. Therefore, this can't be directly matched to any entries.
If your debit transaction is a refund, there's no need for you to add a customer credit. Instead, you can create a Bank deposit affecting Accounts Receivable (AR) to credit the customer's account. This way, it allows you to match the refund transaction with the actual deposit. To do this:
- In your QuickBooks Online account, navigate to +Create and select Bank Deposit.
- In the Account field, select the appropriate Bank Account from which the refund has been made.
- In the Received From column, choose the customer name for whom the refund has been processed.
- In the Account column, select Accounts Receivable (since this impacts the customer’s balance).
- Enter the refund amount under the Amount column.
- Then, click Save and close.

Once done, let's match the bank deposit to the refund in your banking feeds:
- Go to My Apps and select Bank Transactions under the Accounting dropdown.
- Find the refund transaction.
- QBO should automatically suggest the previously created deposit as a match. If not, click Find Match and manually match it to the deposit.
- Confirm the match.
After these steps, verify your customer's balance and ensure there are no discrepancies.
