Why i don't see the A/P aging report in Quickbooks Online?

Hello, cdvtesoreria-gma. 

Thank you for reaching out to the Community. Account Payable report (A/P) is only available in QuickBooks Essentials, Plus, and Advanced. However, if you're using QuickBooks Simple start, you'll need to upgrade your subscription level to have the A/P repost. To upgrade your subscription, please check out this article: Upgrade your QuickBooks Online subscription.  

Additionally, you may want to view this link about Reports included in your QuickBooks Online subscription. 

Also, adding this helpful article to learn more about customizing the details of your financial reports in QBO: Customize reports in QuickBooks Online. 

If you have further questions about this, cdvtesoreria-gma, feel free to reach back out to us here. I hope you stay healthy and enjoy your day!
