Bookkeeping is a low-hazard trade with a high-consequence mistake. Nobody trips over your equipment, but a client can rely on your numbers, file on them and end up with a penalty they want back from you. So the order reverses: professional liability is the main policy, general liability the smaller line.

How much does bookkeeper insurance cost per month?

A solo bookkeeper pays about $32–$55 a month for professional liability and $24–$42 for general liability. A practice of two to five pays about $40–$69, $30–$53, and $56–$97 for a business owner’s policy covering your computers. The class rates about ten percent below the all-trades average.

Buy professional liability first, add general liability for a lease or client visits, then price a BOP against the two apart: our general liability vs professional liability vs BOP guide compares them.

Why E&O matters most, and general liability is the second line

General liability answers injury and physical damage: a client trips in your office, or you knock a laptop off a desk. Nothing you do for a living sits in that policy. A bookkeeper’s exposure is financial loss caused by work, and only E&O answers it, defence costs included.

What an E&O claim looks like for a bookkeeper

Four patterns cover most of what carriers pay on. A misfiled return: the wrong figure goes on a return and the client picks up penalties. A missed deadline: a filing you were engaged to handle goes in late and a relief is lost. A reconciliation error the client relies on: the owner draws against a balance that was never there. A payroll tax filing that goes wrong: a deposit is late and the penalty carries the client’s name. No injury, no broken property, so E&O responds.

Cyber liability, because you hold the client’s bank details

You hold bank credentials, payroll records, home addresses and tax identification numbers for every client, the file criminals want and the breach state notification laws are written about. Cyber liability pays for forensics, notifying those affected, credit monitoring, lost trading time and ransomware costs, and answers the payment-redirection fraud aimed at this trade. That makes it standard now, cheapest as a BOP endorsement.

Bookkeeper insurance cost by practice size

Insurers rate on revenue and headcount, which stand in for how many sets of books you touch and how large the clients are.

Cost by limit, and the limit your contract names

Limits are a per-claim figure over an annual aggregate, and $1M/$2M is what engagement letters, leases and franchise agreements name. Dropping to $500K saves about eight dollars a month and gets the certificate rejected. More in our guide to $1 million liability insurance cost.

Claims-made, occurrence, and the two dates to protect

General liability is normally written on an occurrence basis: it covers work done during the policy year whenever the claim turns up. Professional liability is almost always claims-made: it covers a claim made while the policy is live, and only for work done on or after its retroactive date.

Two dates then matter. Ask a new insurer to match the retroactive date you have carried since your first E&O policy; reset it and every book you closed earlier stops being covered. Tail cover, or extended reporting, holds the window open if you lapse, retire or sell, because a tax season error often surfaces a year later.

What client contracts and franchise agreements ask for

Engagements that put insurance in writing ask for much the same list: professional liability at $1M per claim, general liability at $1M/$2M, a certificate naming the client, often a cyber limit. Franchise agreements add a minimum E&O limit, name the franchisor and require cover for a period after the agreement ends.

How to get the cheapest honest quote

  • Say which services you offer. Bookkeeping, payroll, tax and advisory rate differently.
  • Lead with E&O. Quoting general liability first insures the risk you do not have.
  • Keep your retroactive date. Nothing to carry across, everything to lose.
  • Quote $1M/$2M. A cheaper $500K policy fails the first certificate check.
  • Pay annually and report revenue accurately. Instalments carry a fee; premiums are audited.
  • Compare two or three carriers. The same practice can cost half as much again at one insurer.

Where these numbers come from

Every range starts from the national monthly averages we use site-wide: $45 for general liability, $59 for professional liability, $83 for a BOP. Those scale by the bookkeeping risk class at 0.90, then by size, state and limit, the arithmetic our cost calculator runs. Each range spans a 0.75 to 1.30 carrier spread; base figures sit in how much small business insurance costs.

Frequently asked questions

How much does bookkeeper insurance cost per month?

A solo bookkeeper pays about $32–$55 a month for professional liability (E&O) and $24–$42 for general liability. A practice of two to five pays about $40–$69 for E&O, $30–$53 for general liability and $56–$97 for a BOP. Hiscox advertises E&O from $22.50 a month.

Do bookkeepers need professional liability insurance?

No law requires it, and clients routinely do. Professional liability, or errors and omissions, answers the claim this trade faces: a reconciliation error, a missed deadline, a payroll return that goes wrong. General liability covers none of that, so E&O comes first here.

Do I need cyber insurance as a bookkeeper?

For most practices, yes. You hold client bank details, payroll records and tax identification numbers, so a breach is a real exposure. Cyber liability pays for forensics, notifying those affected, credit monitoring, lost trading time and ransomware costs. It is standard for this trade now, cheapest as a BOP endorsement.

What is a claims-made policy?

A claims-made policy covers a claim made while the policy is live, and only for work done after its retroactive date. An occurrence policy covers work done in the policy year whenever the claim arrives. E&O is nearly always claims-made, so keep your retroactive date when you switch, and buy tail cover if you lapse.

What is the cheapest bookkeeper insurance?

Professional liability at $1M limits from a carrier that rates bookkeeping as its own low-hazard class, from about $32 a month solo. Hiscox advertises E&O from $22.50. Describe your services accurately, pay annually, keep your retroactive date and compare carriers.
