So, what if I want to do a report to show open balances, sorted by product? I can customize to add an 'open balance' field to the Sales by Product/Service Detail report, but the open balance field is always $0 even when I know my customers have an outstanding balance. I'd also like to see any discounts applied on the invoice. I don't want to see a report that is only able to be sorted by customer to do this. I've tried figuring this out for years, but have not been able to do this. Please help.
