Bookkeeping can be a surprisingly profitable business. That's partly because bookkeeping businesses don't have a lot of barriers to entry or even a lot of startup costs to worry about. All you really need is some bookkeeping experience, access to accounting software, and a way to market yourself to prospects.

Bookkeepers and accountants sometimes do the same work, but have a different skill set. In general, a bookkeeper's role is to record transactions and keep you financially organized, while accountants provide consultation, analysis, and are more qualified to advise on tax matters.
