I would like a report similar to the Payments Received report, except listing the total cost for each invoice and the processing fees for each invoice. I honestly can't find one single prebuilt report that lists any costs. In my case, products are being sold. Each product has a cost, and each invoice has a total cost associated with it.

Is there any way to display the costs in a report? Because nothing relating to costs or expenses is an option on any of the reports except for "Sales by item". I also cannot find any way to add "processing fees" using the "customize report" button and on the "Payment Received" report, "shipping charges" is not an option.

I just want to view a "total sales" report for a specified time period, and I want to know how much the customer was charged, the cost of the product(s) on the invoice, the shipping charge, and the processing fee so that I can view my net income for a specified period of time. Any help would be greatly appreciated.
