Quickbooks has tons of options and when I tried it I found it was too complex for what our company needed.
If that's the case for you too, I would definitely suggest starting out with a simple spreadsheet in Excel or on Google docs. Giving all your stuff to an accountant, especially if you're just starting out, is expensive and unnecessary.
If you'd rather not do it yourself, check out
outright.com. It's a simple, easy to use, free bookkeeping tool. We use it and it rocks.
p.s. why are you asking this in the member intro subforum?
