Professional liability (E&O) insurance

5 min read · Reviewed by licensed agents

If you give advice or deliver a professional service, general liability isn't enough. Here's what E&O protects.

Professional liability insurance — also called errors & omissions (E&O) — protects businesses that provide advice or professional services from claims that their work caused a client financial harm. It covers a gap that general liability doesn't.

What it covers

  • Mistakes or errors in your professional work.
  • Failure to deliver a service as promised, or missed deadlines.
  • Negligence claims (even unfounded ones — legal defense is covered).
  • Misrepresentation or bad advice.

E&O vs. general liability

General liability covers physical risks — bodily injury and property damage (a client slips in your office). E&O covers financial harm from your professional work or advice (your error costs a client money). Many service businesses need both.

Who needs it

Consultants, accountants, marketing and IT firms, real estate agents, financial advisors, contractors, and many other service providers. Clients often contractually require it before they'll hire you. Even a baseless lawsuit can cost thousands to defend — which is the core value of E&O.
