The cost of hiring an in-house bookkeeper is more than just their wages. Don’t forget about payroll taxes, workers’ compensation, employee benefits such as health insurance, retirement plan match, various perks, etc. Also, there are many indirect costs such as office space, utilities, trash and other non-wage-related expenses. And then finally there is cost of finding the person in the first place, training them and making sure they are doing a competent job. Lot’s to think about.
