Used bank matching option to show overpayment of invoices. This created a deposit credit and just wondering how can I send a credit notice or the like to my customer?

Hi elgrow143-gmail-,

Thanks for posting in the Community! Matching a bank feed to an overpaid invoice will automatically create a credit in QuickBooks Online. You may create and send a statement to your customer, as this will also show the customer's open credit. Let me walk you through on how to create a statement in QuickBooks Online.

1. On the + New button, select Statement.
2. Select the customer name.
3. On Statement Type, select Open Item or Balance Forward.
4. Select the Statement Date and start and end date.
5. Select Apply.
6. Select Save.

On the other hand, if you prefer to send an adjustment note to your customer instead of a statement, you may need to undo the match in Banking page and create a customer refund in QuickBooks Online. For more detailed steps on how to record a customer refund, you can check this article: Handle customer refunds in QuickBooks Online.
