I want to create an AR aging report that sorted by customer and all there open invoices

You can run the Accounts Receivable Aging Summary report, cjentzsch.

In your QuickBooks Online account, navigate to Reports from the left menu panel and click Standard Reports. Then, follow the steps below:

1. Enter the Accounts Receivable Aging Summary report from the search panel.
2. From there, the report is automatically sorted by customer. Filter the Aging Method and specify the dates from the Report period, Days per aging period, and Number of periods.
3. Then, you can click on the specific amount under the aging period columns to view detailed information about the customer’s open invoices.
4. Then, you can save all customizations made to your reports so you can run the same data in the future.

On top of that, you'll want to seek additional guidance from our QuickBooks Live Expert Assisted team to help you manage financial reports and provide assistance in keeping track of your overall transactions.

I’ll leave this thread available if you have any additional queries.
