Hi AndreaRebel
I think a lot of us want to see the actual total net profit in the sales report, not just the gross profit %. For instance, for the past 12 months, what the net profit amount of the total revenue is, i.e. after deducting the product purchase price from the retail price.
To better clarify my meaning, there is another plugin out there that is doing this, see below. It would be an amazing and essential feature to ATUM Inventory Management.
