Overview
General liability and professional liability sound similar but protect against very different things. One covers physical harm and property damage; the other covers the financial harm caused by your professional work or advice.
Understanding the difference matters, because a claim covered by one is usually excluded by the other. This guide compares them side by side and helps you decide which your business needs — often, it is both.
The short answer
General liability covers third-party bodily injury and property damage — someone slips in your shop, or you damage a client's property. Professional liability (also called errors & omissions) covers claims that your professional service, advice, or work caused a client a financial loss.
If your business interacts with the public or works on client premises, you likely need general liability. If clients rely on your expertise, advice, or deliverables, you likely need professional liability too.
What general liability covers
General liability is the foundational third-party policy. It responds when your business operations cause bodily injury or property damage to someone outside your business, and it covers related legal defense and certain advertising-injury claims.
- A customer slips and is injured at your location.
- You or an employee damages a client's property while working.
- A third party claims your advertising caused them harm.
What professional liability covers
Professional liability — errors & omissions (E&O) — responds to claims that your professional work caused a client financial harm, even when no one was physically injured and no property was damaged. It is essential for businesses that sell expertise.
- A client claims your advice or service led to a financial loss.
- You are accused of a mistake, oversight, or missed deadline.
- A deliverable did not perform as the client expected.
Key differences at a glance
The simplest way to keep them straight: general liability is about physical harm to others, while professional liability is about financial harm from your work.
- Type of harm — bodily injury and property damage vs. financial loss.
- Who it protects you from — the general public and clients on-site vs. clients relying on your work.
- Common buyers — almost every business vs. service, advice, and expertise-based firms.
- Overlap — a claim covered by one is generally excluded by the other, which is why both are often needed.
Which one does your business need?
Most businesses that serve the public start with general liability. Service firms — consultants, agencies, accountants, designers, IT providers, and many healthcare and financial businesses — add professional liability because their biggest exposure is a dissatisfied client, not a slip-and-fall.
Many businesses carry both, sometimes bundled into a business owners policy alongside property coverage. An agent can help you decide based on your specific work.
