General Liability vs. Professional Liability: Do You Need Both?

Last reviewed: September 22, 2026
General liability covers third-party bodily injury and property damage, someone trips in your shop, or your crew damages a client's property. Professional liability, also called errors and omissions, covers financial harm from a mistake in the advice or service you provided. Most businesses that give advice, design, or perform a service beyond physical work need both, not one or the other.
What general liability actually covers
- Bodily injury to a customer or visitor on your property
- Property damage your business causes to someone else's property
- Advertising injury claims, like using someone else's copyrighted material by mistake
What professional liability actually covers
- A claim that your advice, design, or service caused someone financial loss
- Errors, omissions, or missed deadlines in a professional service
- Legal defense costs even if the claim turns out to be groundless
Why one doesn't substitute for the other
General liability won't respond to a claim that your service itself was the problem, no injury, no property damage, just a client saying your work cost them money. Professional liability won't respond to a customer who slips and falls in your office. They're built for different kinds of claims.
Who typically needs both
Contractors, consultants, designers, real estate professionals, and anyone who mixes hands-on work with advice or design services. A business that's purely retail with no advisory component may only need general liability.
Common questions
Does a BOP include professional liability? No. A standard Businessowners Policy includes general liability but not professional liability, that's a separate policy or endorsement.
How do I know if my work counts as "professional services"? If a client could argue your advice, design, or judgment cost them money, that's a professional liability exposure. Tell me what you do and I'll tell you straight whether you need it.
Send me a description of what your business actually does and I'll tell you where the gap is.
