If you're doing any sort of volume at all, I think you should save the cost on something like Quick Books, and find a good bookkeeper to do it for you. Sell what you sell, and leave the bookkeeping and accounting to the pros. We have a company that handles bookkeeping, accounting, and payroll, all under one roof. You can find someone to to bookkeeping one a week or once a month for not a lot of money. You don't have to dive right into the accountant or anything, but consider what your time is worth and how much you know about that sort of stuff!
