First, the bottom line: Every retail business must track finances (income, expenses, and taxes) and inventory. For novice businesspeople, the idea of keeping these records may seem challenging, but don’t fear. Popular software programs — particularly QuickBooks — make it possible for you to manage inventory, income, expenses, and taxes with a relatively small learning curve (usually one or two days) and usually for less than $300 a year. In fact, if you want to skip this chapter entirely, buy QuickBooks Pro and find a one-day course in your area that explains how to use the program, if necessary. We should also note that Microsoft recently unveiled its own business accounting program and the newest version of it, Office Accounting 2008, included several eBay features.
