but you closed the comments too fast for me
what I mean is, in my understanding the report should give you an overview about the expenses and income you have. but this can only give you an accurate result if you consider the "Cost price" of a product from the catalog into this calculation.
i.e. I sell apples, I buy 1000 apples for 1 euro each (I have an expense of 1000,- euro), I re-sell them for 2 euro again (wich I create invoices for).
now the report says, I have 2000,- euro profit. but I don't have 2000,- euro profit, I need to subtract the 1000,- euro, wich I payed for them.
so my real profit would be only 1000,- euro.
do you understand what I mean?
