Your confusion ends here, @CyberSpyder.

Allow me to provide further details on your concern and help you from there.

The main cause of this problem is the payments or the delayed charges linked to an invoice. That said, you'll have to remove/delete every payment or charge from your sub-client to get this corrected. Since you don't have the option to remove the charges, you can delete the payment instead. To do so, you can click the 1 payment made link under the Payment Status section, then select More and choose Delete in the Receive payment window.

If you get the same issue, I suggest reaching out to our QuickBooks Support Team. This way, they can further check on this matter and provide additional steps to get this resolved. 

In the future, you might want to review all the sales transactions made in QuickBooks. You can go to the Sales menu and select All Sales.

I'm still open to your replies, @cjloveconsulting. If you have any additional questions about your concern, don't hesitate to leave a comment below. I'll be around to provide further assistance.
