Errors and Omissions (E&O) insurance — also called Professional Liability insurance — protects your business against claims that your professional services caused a client financial harm.
General Liability covers physical harm: someone slips, property gets damaged.
E&O covers economic harm from your professional work: bad advice, missed deadlines, errors in contracts, failure to perform services as promised.
Most E&O policies are written on a claims-made basis — meaning the policy in force when the claim is filed pays the claim, regardless of when the error occurred. This makes continuity of coverage critical.
