What is the difference between general liability and professional liability?

General liability covers physical harm your business causes, such as bodily injury and property damage to others. Professional liability (errors and omissions) covers financial harm to clients from your advice, services, or work product, such as mistakes and negligence.

Do I need both general liability and professional liability?

If your business both performs physical work and provides expertise or advice, you likely need both. Examples include design-build contractors, IT firms that install hardware, and medical spas. A business that only faces physical risk may need only general liability.

Does a Business Owner's Policy include professional liability?

Usually not. A Business Owner's Policy typically bundles general liability with commercial property but does not include professional liability. E&O coverage is generally added as a separate policy or endorsement.

How much do general liability and professional liability cost in 2026?

General liability commonly runs about $40 to $100 per month for many small businesses, with the median near $45 per month. Professional liability often runs about $50 to $150 per month for small service firms. Actual pricing varies by industry, revenue, location, and limits.

General Liability vs Professional Liability: Which Does Your Business Actually Need?

Quick answer: General liability covers physical harm your business causes, bodily injury to others and damage to their property. Professional liability (also called errors and omissions, or E&O) covers financial harm from your advice, designs, or services, mistakes, missed deadlines, and negligence claims. If your business can hurt someone or damage property, you need general liability. If clients pay you for expertise, you also need professional liability. Many businesses need both.

These two policies get confused because both have "liability" in the name and both defend you when someone sues. But they cover completely different kinds of harm, and buying one when you needed the other leaves a gap that shows up at the worst possible moment. Here is how to tell them apart and decide what your business actually needs.

What does general liability cover?

Commercial general liability (CGL) is the foundation policy for almost every business. It covers third-party bodily injury, third-party property damage, and personal and advertising injury, the physical and reputational harm your operations can cause to people outside your business.

Real examples:

A customer slips on your wet floor and breaks a wrist.
Your crew knocks over a client's antique while working on their property.
Your advertising is accused of copying a competitor's slogan.

General liability pays for the injured party's medical bills or repair costs, plus your legal defense, up to your policy limits. It is standardized around the ISO CGL form used industry-wide (ISO commercial general liability).

What does professional liability cover?

Professional liability, also known as errors and omissions (E&O), covers financial losses a client suffers because of your professional work, not physical injury. It responds when someone claims your advice, service, or work product was negligent, wrong, incomplete, or late, and it cost them money.

Real examples:

An accountant files a return with an error that triggers penalties for the client.
A consultant's flawed recommendation causes a client to lose a contract.
An architect's drawings contain a mistake that forces expensive rework.
A software developer misses a deadline and the client loses revenue.

In every one of these, no one is physically hurt and nothing is physically broken. The harm is purely financial, which is exactly the gap general liability does not fill.

General liability vs professional liability: side by side

	General Liability	Professional Liability (E&O)
Covers	Bodily injury, property damage, advertising injury	Financial loss from your professional services
Trigger	Physical harm to a third party	Negligence, errors, or omissions in your work
Typical claimant	Customer, visitor, passerby	A client who paid for your expertise
Classic example	Slip and fall in your shop	Bad advice that costs a client money
Who needs it	Nearly every business	Service and advice-based businesses

Which one does your business need?

Businesses that mainly need general liability

If your risk is physical, GL is the core policy. Contractors, retailers, restaurants, cleaning companies, landscapers, and manufacturers all face slip-and-falls, property damage, and product-related claims. For a California contractor, general liability is also frequently required to satisfy a general contractor's contract and to keep your license bond and jobs in good standing.

Businesses that also need professional liability

If clients pay you for knowledge, judgment, or a service, you carry professional risk that GL will not touch. Consultants, accountants, bookkeepers, architects, engineers, IT and software firms, real estate agents, insurance and financial professionals, marketing agencies, and health and wellness practitioners all fall here. A single "you gave me bad advice" lawsuit can cost far more than the fee you earned.

Businesses that need both

Plenty of businesses sit in both worlds. A design-build contractor both performs physical work (GL) and provides design services (professional liability). An IT company that installs hardware on-site risks property damage (GL) and also risks a costly configuration error (E&O). A medical spa faces slip-and-falls (GL) and treatment-outcome claims (professional liability). If you both do physical work and sell expertise, assume you need both until an agent confirms otherwise.

What about a Business Owner's Policy (BOP)?

Many small businesses buy general liability bundled with commercial property in a Business Owner's Policy (BOP), which is usually cheaper than buying each separately. A BOP typically does not include professional liability, so if you need E&O, you generally add it as a separate policy or endorsement. Do not assume a BOP covers your professional risk, it almost never does.

What each typically costs in 2026

Prices vary widely by industry, revenue, location, and limits, so treat these as typical ranges rather than quotes:

General liability: for many small businesses, roughly $40 to $100 per month, with higher-risk trades like construction running more. Industry surveys put the median GL policy near $45 per month. (MoneyGeek, 2026)
Professional liability / E&O: commonly $50 to $150 per month for small service firms, driven by your revenue, the size of contracts you handle, and how much financial harm a mistake could cause.

The exact number depends on your specific operations. The cheapest policy is never the goal; the right coverage for your actual exposure is.

The bottom line

General liability answers the question "what if my business physically hurts someone or damages their property?" Professional liability answers "what if my work or advice costs a client money?" Most businesses need the first. Many also need the second. The mistake is assuming one covers the other, because it does not.
