In this guide
General liability insurance covers claims that your business physically hurt someone or damaged their property, like a customer tripping in your office. Professional liability insurance (also called errors and omissions, or E&O) covers claims that your work or advice caused a client financial harm, like a missed deadline or a costly mistake. Many service businesses need both, because each one generally excludes what the other covers.
Key takeaways
- General liability is about physical harm and certain "personal and advertising" injuries to people outside your business.
- Professional liability is about financial harm caused by errors, negligence, or bad advice in the services you provide.
- A standard general liability policy or business owner's policy (BOP) does not include professional liability.
- Most professional liability policies are "claims-made," which affects what happens when you switch insurers or close your business.
- Contracts, licensing boards, and state laws can require one or both.
The short answer
Think about how someone could be harmed by your business. If they could be injured, or their property damaged, because of your location or operations, that is a general liability risk. If they could lose money because your professional work was wrong, late, or incomplete, that is a professional liability risk.
A bakery's biggest liability risk might be a customer slipping on a wet floor. An accountant's might be a client facing tax penalties because of a filing error. A web developer might face both: a visitor tripping over a cable at a client meeting, and a client claiming a bug cost them sales.
What general liability covers
Commercial general liability (CGL) insurance protects against claims from third parties, meaning people outside your business such as customers, vendors, and visitors. According to the Insurance Information Institute (Triple-I), a CGL policy typically covers:
- Bodily injury and property damage caused by your premises or business operations, arising from what Triple-I calls "non-professional negligent acts."
- Personal and advertising injury, which includes offenses such as libel, slander, and copyright infringement in your advertising.
- Medical payments for non-employees injured on your premises, usually paid regardless of fault.
- Legal defense and damages you are found liable for, up to your policy limits.
What general liability usually excludes
Standard CGL policies generally exclude professional liability, injuries to your own employees (covered by workers' compensation), employment practices claims, liquor liability, and most pollution claims. They also don't cover damage to your own property. Exclusions vary by policy, so read yours carefully.
What professional liability covers
Professional liability insurance protects businesses and individuals who provide expert services or advice. Triple-I explains that it pays the cost of legal defense against covered claims and judgments against you, up to the policy limit. It covers claims such as:
- Negligence, such as failing to meet the standard of care expected in your profession.
- Errors and omissions, like a mistake in a report or leaving out a key step.
- Misrepresentation of what your service would deliver.
- Inaccurate advice that a client relied on and lost money.
Defense costs matter a lot here. A client can sue you even when you did nothing wrong, and paying a lawyer to respond can be expensive. Professional liability can help with those costs even if the claim has no merit.
What professional liability usually excludes
Triple-I notes that professional liability generally does not cover non-financial losses or losses caused by intentional or dishonest acts. It also isn't designed to cover bodily injury on your premises. That's the job of general liability.
Good to know: Professional liability goes by different names depending on the field. Doctors usually call it malpractice insurance, while consultants, tech firms, and real estate professionals often call it errors and omissions (E&O). The core idea is the same.
Side-by-side comparison
| General liability | Professional liability (E&O) | |
|---|---|---|
| Main risk | Physical injury or property damage to others | Financial loss from your professional work |
| Typical claim | A customer slips and falls in your store | A client says your error cost them money |
| Also covers | Personal and advertising injury, such as libel or slander | Negligence, misrepresentation, inaccurate advice |
| Who usually needs it | Nearly any business that deals with the public, has a location, or works on client sites | Businesses that sell expertise, advice, or professional services |
| Included in a BOP? | Yes, usually | No, bought separately or as an endorsement |
| Common policy trigger | Often occurrence-based | Usually claims-made |
Who needs which coverage
Businesses that often need general liability
Almost any business that has customers visiting, works at client locations, sells products, or advertises can face general liability claims. That includes retail stores, restaurants, contractors, salons, and many offices. Landlords often require tenants to carry it, and the U.S. Small Business Administration describes general liability as coverage that applies to any business.
Businesses that often need professional liability
Triple-I lists professions that should consider professional liability, including:
- Accountants and investment advisors
- Architects and engineers
- Graphic designers and software developers
- IT and management consultants
- Insurance professionals and real estate agents and brokers
Triple-I notes the list is not complete. Some states require professional liability for certain professions, especially attorneys and doctors. Clients may also require it in contracts before they hire you.
Businesses that often need both
Many service businesses have both kinds of risk. A consultant who meets clients in person, an architect who visits job sites, or a marketing agency that writes ad copy could face a slip-and-fall claim one month and a "your work cost us money" claim the next. Carrying only one leaves a gap.
Tip: Ask yourself two questions. "Could someone get hurt or have property damaged because of my business?" and "Could a client lose money if my work had a mistake?" A "yes" to the first points toward general liability. A "yes" to the second points toward professional liability.
Claims-made vs. occurrence policies
This is one of the biggest practical differences between the two types of coverage, and it trips up many business owners.
- Occurrence policies cover injuries or damage that happen while the policy is active, even if the claim is filed years later. General liability is commonly written this way. The International Risk Management Institute (IRMI) notes that virtually all contracts requiring someone to carry general liability ask for an occurrence-based policy.
- Claims-made policies respond to claims made while the policy is active. Triple-I explains that for most professional liability policies, the policy must be in effect both when the event took place and when the lawsuit is filed for a claim to be paid.
Claims-made policies often include a retroactive date. Work done before that date is generally not covered, even if the claim comes in while the policy is active. That's why keeping continuous coverage, and carrying the same retroactive date when you switch insurers, can matter.
Watch out: If you retire, close your business, or let a claims-made policy lapse, a client could still sue you later over past work. "Tail coverage" (an extended reporting period) lets you report claims made after a claims-made policy ends, as long as the work in question was done while the policy was active. It usually costs extra and must be arranged in time.
How the two fit with other business insurance
General liability is often bought as part of a business owner's policy, which also bundles commercial property and business income coverage. Triple-I notes that professional liability is not included in a BOP or in in-home business policies, so it has to be added separately. Neither policy covers vehicles you use for work, which typically calls for commercial auto insurance.

How to shop for liability coverage
- Check requirements first. Look at your leases, client contracts, and any licensing rules for your profession. They may set required coverage types and limits.
- Describe your work accurately. Insurers price based on what you actually do. Misdescribing your services could create problems at claim time.
- Compare more than price. Look at limits, deductibles, exclusions, whether defense costs reduce your limit, and for claims-made policies, the retroactive date and tail options.
- Get several quotes. Comparing quotes from multiple insurers for the same coverage can help you understand what's typical for your field.
- Ask questions. A licensed agent or broker who works with businesses like yours, or your state insurance department, can help you understand your options.
Frequently asked questions
Is professional liability the same as general liability?
No. General liability covers bodily injury, property damage, and certain personal and advertising injuries. Professional liability covers financial harm caused by errors, negligence, or inaccurate advice in your professional services. Each typically excludes what the other covers.
Is E&O insurance the same as professional liability?
Generally, yes. Errors and omissions (E&O) is another name for professional liability insurance, commonly used in fields like consulting, technology, and real estate. In medicine, it's usually called malpractice insurance.
Does a business owner's policy include professional liability?
Usually not. A BOP typically bundles general liability, property, and business income coverage. Professional liability is generally bought as a separate policy or, in some cases, added by endorsement to a commercial package policy.
Do freelancers need liability insurance?
It depends on the work. Freelancers who give advice or deliver professional work often consider professional liability, and those who meet clients in person or work on-site may also want general liability. Some clients require proof of coverage before signing a contract.
What happens to my professional liability coverage if I retire?
If your policy is claims-made, coverage generally ends when the policy does. Tail coverage can let you report later claims about work done while the policy was active. Ask your insurer about options and deadlines before the policy ends.
