@NickMan1313   Same problem, three years later.  I called QBO yesterday to ask why they haven't added the customer option to the AP report yet for construction and architecture projects. He said he would look into it and get back me with next week. Yeah, ok, right. I feel like when I call or work with QBO, I have to tell their support team how their product works (or does not work). In the meantime, have you found a QBO resolution rather than switching over to Sage Construction & Real Estate or building your own Excel spreadsheets from exported QBO reports?  All I want to see is the AP aging report filtered by customer versus vendor (with the vendors in a column as shown on the Purchases by Vendor Detail Report).  Not rocket science, especially for an accounting software company, right?
