Two Different Policies, Two Different Risks
General liability covers physical injury and property damage claims from customers, clients, or the public. Professional liability, also called errors and omissions insurance, covers financial harm caused by mistakes, negligence, or failures in the professional services or advice you provide. They protect against entirely different kinds of claims, which is why most service based businesses end up carrying both rather than choosing between them.
General liability protects against the everyday physical risks of running a business: a customer injured on your premises, property damage your business causes to someone else, and certain advertising related claims like defamation or copyright disputes. It also covers your legal defense costs if a covered claim leads to a lawsuit, even one that is eventually dismissed.
This is the policy most businesses buy first, since it applies broadly regardless of industry. For a full breakdown of what it covers and does not cover, see what general liability insurance covers.
Professional liability, often shortened to E&O, covers claims that your professional advice, services, or work caused a client financial harm, rather than physical injury or property damage. An accountant who makes an error on a client's tax filing, a consultant whose recommendation leads to a financial loss, or a designer who misses a critical deadline specified in a contract can all trigger a professional liability claim, even when no one was physically hurt and nothing was damaged.
This distinction matters because general liability simply does not respond to these situations. A client claiming your advice cost them money is a completely different category of risk than a client claiming you damaged their office, and insurers price and structure the two coverages separately for exactly that reason.

| Protects against | Bodily injury, property damage, advertising claims | Financial harm from professional errors, advice, or missed obligations |
| Typical claim example | Customer slips and falls in your store | Client claims your advice caused a financial loss |
| Who typically needs it | Almost every business | Consultants, accountants, designers, IT firms, and other advice or service based businesses |
| Typical annual cost | $500 to $1,500 | $500 to $3,000, depending on the profession and risk exposure |

Seeing how each policy actually responds to a real claim makes the difference easier to hold onto than the table alone.
The pattern worth noticing is that the general liability scenario involves something physical going wrong, while the professional liability scenario involves the work itself being the problem. That distinction is the entire basis for why the two policies exist separately rather than as one combined coverage.
For most service based businesses, the honest answer is yes. General liability handles the physical and reputational risks that come with simply operating a business, while professional liability handles the financial risk tied specifically to the quality or accuracy of your work. A consulting firm that only carries general liability has no protection at all if a client sues over bad advice, and a firm that only carries professional liability has no protection if a client is injured during an in-person meeting at their office.
Businesses with no advisory or service component, such as a retail shop that only sells physical products, often find general liability alone is sufficient, since there is no professional advice being given that could trigger an E&O claim. The deciding factor is not company size or revenue but whether your work product could plausibly be blamed for a client's financial loss.
No. Businesses that do not provide advice, services, or specialized expertise as their core offering, such as most retail and product based businesses, typically do not need it. Any business where a client could reasonably claim your work, advice, or judgment caused them financial harm should seriously consider it, even if the business is small.
General liability is usually the less expensive of the two for a comparable small business, typically running five hundred to one thousand five hundred dollars a year. Professional liability costs vary more widely, from around five hundred to three thousand dollars a year, since pricing depends heavily on the specific profession and how much financial exposure a single error could create.
General liability and professional liability are not competing options where you pick the better one. They cover distinct categories of risk, and for any business that gives advice, performs specialized services, or could be blamed for a client's financial loss, carrying both is the standard, not the exception. Understanding the difference now means you are not discovering a coverage gap the moment a claim actually happens.
