Can I run an aged debt report by product code. I just want to know who owes for particular things. Can I do that?

Yes, you can, eleanor-ryan-lei.

In QuickBooks Online, I recommend running and customising the Sales by Product/Service Detail report to view who owes the particular item.

Here's how:

1. Go to the Report menu and type Sales by Product/Service Detail in the search field.
   
   
2. Open the report, then click Customise.
   
   
3. Make sure the dates are correct.
4. Under Rows/Columns, place a checkmark beside SKU.
   
   
5. On the Filter section, go to A/R Paid and choose Unpaid.
6. After that, hit Run report.
   
   

That should do it, eleanor-ryan-lei. Please keep me posted in this thread if you need other reports to view or  pull up important data in your books. I'd be glad to help you out.
