Customer overpaid invoices. How do I apply payment to match EFT in bank?

Hi bookkeepermd, 

Handling a customer's overpayment is made simple in QuickBooks Online. We know how important it is to be able to account for mishaps such as these, and I'd be happy to explain your next steps. 

When a customer overpays, you can use the credit toward an invoice, refund the customer, or enter the overpayment as a tip in QuickBooks.

This is a great article that will guide you through the steps: Handle a customer credit or overpayment in QuickBooks Online. 

Once you've recorded the overpayment, you'll now be able to match your invoice with your bank statement. 

I hope this helps get you back on track. If you have any other questions, please don't hesitate to reach out to our tech support team. 

Cheers.
