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.

Bookkeepers earn a median annual salary of $45,860, according to the U.S. Bureau of Labor Statistics (BLS). However, a bookkeeper's salary varies depending on their education, location and level of experience. The BLS projects employment for bookkeeping, accounting and auditing clerks to decline by 6% by 2032.
