Startup philosophy

I would love to give five stars as it is easy to use, and that is (almost) everything.
The problem, is that it is missing the most fundamental feature, that all businesses (except for over financed startups it seems) is PROFIT CALCULATION!
I spend time entering my costs but it cant for some crazy reason tell me how much I made on a sale (therefore that month) ..........nuts
