Thanks for getting back to us and following the steps provided by my colleague above, @DJ33.
An open balance will show in the report if the entire amount of the estimate was not used to create an invoice (Progress Invoicing). For example, when you create a 500 worth of estimate and convert only half of it to an invoice. The uninvoiced balance will reflect on the Open Estimate report since a remaining amount is waiting to be converted into an invoice.
If you still see an open balance in this report, we can use it to convert another invoice. This way, it will zero out the remaining balance on your Open Estimate report.
In case you need to customize your transaction reports in the future, you can refer to this article: Customize reports in QuickBooks Desktop.
