I am on Quickbooks Online and the interface is similar as you describe, but that is not solving the issue I described.  I have a multiple customer locations, restaurants. Each location is created and invoiced as a different customer.  I have a parent customer setup for these, but as I said, I invoice for each location.  The payment comes at once for multiple locations (customers).  If I select the parent customer it does show all the invoices for the locations in the transaction list, that is great.   When I select to receive a payment it goes to a screen where the parent customer is selected, however, no invoices are shown because the invoices are per location.  It would be great if it would show the open invoices on that page, but it does not.  Thanks again, would be a great improvement.
