In QB Online, is there a way to run AR and AP aging reports by transaction (invoice) dates, instead of due dates? This was easy to do in QB Desktop.

Glad to have you here, Jimbozeubuen.

The Accounts receivable aging detail and Accounts payable aging detail reports are set to show transactions grouped by days of past due. Instead, you can run the Transaction Detail by Account report and customize the filters to group AR/AP transactions by invoice dates.

Here's how:

1. Go to Reports.
2. Enter Transaction Detail by Account in the search field.
3. Click the Customize button.
4. From the Filter drop-down, mark the following boxes:
   Transaction Type and choose Invoice.
   Account and choose All Accounts receivable.
   Service Date and choose the your preferred period date.
   
5. Click Run report.

Here's a sample screenshot on how the report would look like after applying the customization above.

I'm also adding the following resources to learn more about customizing reports in QBO: Customize reports in QuickBooks Online.

Having the option to group the aging reports by invoice dates instead of due dates is a good idea. While we continue to work in making sure we meet our customers needs, please check out our QuickBooks Blog to be updated with our product's latest feature release.
