Can someone explain why the per project costs never adds up to the amount I was billed that month? It seems to be higher.

$30.56* (yellow)* + $12.79 *(green) *= $43.35 but it shows $43.29 (which I was billed).

I'm not 100% sure but it almost seems like the per project totals are changing. I will check again tomorrow now that I have them recorded and see if they are still the same.

Also, I wish the invoice and receipt would show a breakdown per project of the total cost (minus any taxes if that's too complicated), as well as the total billed amount. Heroku does this and it made my expense tracking easier.

The reason for this is I have two apps I keep different spreadsheets for tracking expenses for tax purposes. But really it all adds up under the same business income/expenses. So I want the total to match what I was actually billed but be able to list each project separately. When I add up the two costs I get a number that's higher than what I actually billed, meaning technically I'm going to overdeduct on my taxes when I add them up separately. Even though it's pennies or dollars, it could add up over a period of time and I want everything to be tracked accurately.
