Thanks for your prompt response and for sharing more details, @Jimbozeubuen.

Currently, running AR and AP aging reports by invoices services dates is unavailable in QuickBooks Online.

I know how beneficial it is when we could run this kind of report in QBO. Please know that I'm taking note of this one. In the meantime, I encourage you to visit our QuickBooks blog site for updates such as feature release and product enhancements.

Also, you can try new features in our QuickBooks Labs like QuickBooks Themes and Community Reports shared by others. Just go to the Gear icon and then select QuickBooks labs under  Your Company section.

Feel free to place a comment or tag me (@Jovychris_A) if there's anything else. I'm always around to help. Take care!
