Hello ablreno,
I know how important it is to be able to view old transaction information. QucikBooks Online allows you to navigate through tons of helpful reports in order to see your business data quickly and easily. I'd be happy to explain which report would be best in this situation.
To see invoices older than 15 months, try running the Invoices and Received Payments report. This report will show you the payments you've received, and the invoices that go with them. To find this report, click the Reports tab on the left navigation menu, then search for it in the search bar.
If you're looking for a list of invoices that haven't received payments yet, you can run the Open Invoices report.
Once you're on the report, you can modify the date-range at the top of the page to see the data you're looking for.
That's all there is to it! I hope this helps you find the right information. If you have any other questions, please don't hesitate to reach out to our tech support team.
Cheers!
