Bookkeeper E&O typically costs $300 to $900 a year for a solo practice — cheap insurance for a profession whose errors propagate into clients’ taxes, loans, and decisions. Payroll and filing responsibility are the price steps: the more you file on clients’ behalf, the more a mistake costs someone, and the policy prices accordingly.

What moves the price
Services drive everything: reconciliation-and-categorization work prices at the floor; payroll processing, sales-tax filings, and CFO-lite advisory each add a step. Client count and revenue set scale, claims history sets trajectory, and holding client bank credentials makes cyber the companion purchase carriers increasingly expect — a bookkeeper’s laptop is a multi-client incident waiting for an MFA prompt.
How bookkeeper pay less without cutting coverage
Describe services precisely — “bookkeeping” applications that quietly include payroll build coverage gaps, while over-described services buy premium you don’t need. Engagement letters defining scope are the profession’s best claims defense and a common underwriting credit. Pair E&O with a small cyber policy from the same market for package pricing.
