Question about reports

I have been selling on Amazon for years, but I’ve never been good at the books so we hired a bookkeeper. Starting in January they are raising their rates by $75 from $330 to $405 a month so it’s time to make some changes.

What reports should I be running and how often should I run them? Besides the basics needed for accurate bookkeeping, I’d like to be able to see the total proceeds after fees from each sale. Using that I can get an idea of just exactly how much profit is being made. I have an idea, usually within a dollar, but I’m not dead on like I’ll need to be going forward. Thanks in advance!
