Professional liability insurance, also called errors and omissions insurance (E & O insurance), protects the business if sued for negligence. You may want this policy if the business provides a professional service or regularly gives advice to clients or is requested by a client to have professional liability insurance to complete a contract.
General Liability provides coverage for an insured when negligent acts and/or omissions result in bodily injury and/or property damage on the premises of a business, when someone is injured as the result of using the product manufactured or distributed by a business, or when someone is injured in the general operation of a business. The policy also covers Personal and Advertising Injurt which covers the insured for certain offenses the insured commits in the course of business, such as libel, slander, disparagement, or copyright infringement in their advertisements.
