In the comments, Drew asked how to go about learning to use QuickBooks.

I learned to keep my own books with the help of a very patient accountant and copies of Bookkeeping for Dummies and Accounting for Dummies. Unless you already know what you are doing, the world of debits, credits, and double-entry accounting is a bit complicated. And although QuickBooks makes it a lot easier, you probably should get an accountant’s help to set up your books and get you started.
