General Liability vs Professional Liability: The Difference
General liability vs professional liability comes down to the kind of harm: the two cover different things, and many businesses need both. General liability is about physical harm: someone is hurt or their property is damaged. Professional liability, also called errors and omissions, is about financial harm: your work or advice cost a client money. Buying one does not cover the other.

The short answer
If your business can physically injure someone or damage their property, you need general liability. If a client can sue you because your work or advice caused them a financial loss, you need professional liability. A contractor who also does design or consulting often needs both: general liability for the job site, professional liability for the advice [III: business insurance basics, 2026-05]. Neither policy covers the other's claims.
What general liability covers
General liability responds to third-party bodily injury and property damage your operation causes, plus the legal defense, including products-and-completed-operations claims after a job is done [III: business insurance basics, 2026-05]. It is the policy a client contract, landlord, or license typically requires. It does not respond to a claim that your advice or professional work was wrong and cost the client money, even if the dollar loss is large. See the general liability coverage page.
What professional liability covers
Professional liability, or errors and omissions, responds when a client alleges your professional service, advice, or work product caused them a financial loss: a missed deadline, a design defect, a filing error, a recommendation that lost money [NAIC: small business insurance, 2026-05]. It is the core policy for consultants, agencies, accountants, attorneys, architects, and other licensed professionals, and many of those licenses require it. It does not respond to someone tripping in your office; that is general liability. See the professional liability coverage page.
Who needs both general and professional liability?
Any business that both does physical work and gives advice or design needs both: a contractor who also designs, an IT firm that installs hardware and consults, a trainer who programs and supervises. The test is simple: can you physically hurt someone or their property (general liability), and can a client lose money because of your judgment (professional liability)? If both are yes, one policy leaves half your exposure uncovered. Carriers often sell them together; ask any carrier whether the quote covers both lines and at what limit.
Where to get quotes
Quote the lines you actually need, not a generic bundle. If your real risk is advice, lead with a professional-liability-strong carrier; if it is a job site, lead with a general-liability-strong one; if both, price a carrier that writes both well. Get two or three quotes, and see what drives the cost of each line before you commit. See /methodology/ for what to look for in coverage depth on any plan.
