Thanks for getting back to us, @jaygar.

There are two possible reasons why you've received the Customer Balance error. And I'd like to share them with you and help you from there.

Here are the following reasons:

• The open invoices have another associated A/R account.
• The open invoices might be in a job beneath the selected customer.

To get this fixed, you'll have to view the account of the open invoices, then select the appropriate account from the A/R Account drop-down.

Also, if there's a job under the selected customer, you'll have the select that specific job or customer in the Received From drop-down.

You can read this article for more details: Record an invoice payment.

As always, feel free to visit our QuickBooks Community help website if you need tips and related articles in the future.

Keep in touch if you need further assistance with this, or if there's anything else I can do for you. I've got your back. Have a good day.
