Professional liability protects a business from claims specifically related to performing their professional service. Professional liability is used for negligence claims, misrepresentations, and errors or omissions, related to a professional service on behalf of a client.
General liability protects a business from claims in which all businesses are at risk. General liability insurance coverage is used against any claim alleging bodily injury, property damage, personal injury (such as defamation of character like slander and libel), advertising injury, and damage to leased premises.
