I can provide you with clear guidance on deleting and receiving payments in both your parent and sub-accounts, mattstas1234.

To clarify the steps provided by our colleague Erika_K is to ensure you can untick the Bill parent client box which is an essential step to exclude the sub-client open invoices when you create a statement for the parent client.

If there are no payments to delete, let's consider the possibility of the existence of past sub-client invoices that were paid by the parent client which is the cause of the error when you tried to untick the box. I suggest running the Invoices and Received Payments report to view all paid invoices associated with the parent and sub-client.

Here's how:

1. Go to Report, then look for the Invoices and Received Payments Report.
2. Look for the Report period, select All Dates
3. Find the Customize button.
4. Filter (Place a checkmark for the parent and sub-client at issue).
5. Hit Run report.

If there are Payment transactions listed on the report, I suggest clicking on the payment transaction if it shows that the parent client paid the sub-client invoice. If this is the case, please know that the only way is to delete and recreate the invoice payments and ensure that the sub-client invoices are paid by the sub-client.

Once done, you can untick the Bill parent client box and move past the error. I understand that this is a long process. Therefore, I suggest downloading the PDF statement for the parent client and editing it outside of QuickBooks Online (QBO), as a workaround.
