Customer Open Balance is incorrect on QuickBooks Desktop

I have a workaround to fix the customer's balance in QuickBooks Desktop, @peter zhu. Happy to share the detailed steps to correct the issue. 

I know that keeping an exact balance is crucial for maintaining the accuracy of books and reports. Let's collaborate to find a speedy solution to the issue.

We are still looking into the issue of the wrong amount showing up after applying credit to an Accounts Receivable (A/R) and a Journal Entry (JE). I suggest getting in touch with our customer care agents so they can add you to the list of affected users. You'll receive an email with investigation updates once fixed.

Proceed with the following steps:

1. Press F1 on your keyboard to open the Help page.
2. Click Contact Us.
3. Enter your concern in the box and select Continue.
4. Choose either Start messaging or Get a callback.
5. Complete the required data and submit the request.

But no worries, we have a workaround for this case. Ensure the A/R is on the first line of the JE. If it's on the second line, I'd suggest deleting and entering again to help balance things out. 

1. Press Ctrl + A to open the Chart of Accounts page. 
2. Locate the bank and double-click the Journal Entry you created. 
3. Hit the Delete button on the upper left side. 
4. Re-enter it again with AR on the first line. 

Furthermore, any credit memos that show an incorrect balance must be deleted and recreated. 

1. Go to the Customers menu and select the Customer Center tab. 
2. Find the customer's name in the list and double-click the credit memo. 
3. Hit Delete.
4. Create a credit memo again.
