Q1. How do bookkeepers calculate a defensible monthly fee per client?
Bookkeepers calculate a defensible monthly fee by estimating transaction categorization time (~1 hour per 50 transactions), adding fixed hours for selected services (such as payroll, sales tax, or monthly reporting), applying a client complexity factor (0.85x to 1.35x), and multiplying total hours by a target rate ($55–$95/hour). Flat monthly billing is recommended over hourly billing for predictable revenue.
