A bookkeeping side hustle offers incredible flexibility. It allows you to balance work with personal life. It also opens opportunities to work with a wide range of clients from different locations.

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.

Yes, a bookkeeping business can be very profitable. In fact, ZipRecruiter reports that the national average income for an independent bookkeeper is $56,100, though some report income as high as $122,000. The cost of doing business is relatively low, mostly related to bookkeeping software, so profit margins are high.

Connect remotely to your client's computer to balance the books, just like if you worked on-site. Work through an online cloud-based bookkeeping software (such as QuickBooks Online or Xero) with your own secure login. Use the same desktop software you're used to, but accessed through a hosted virtual desktop.
