General liability and professional liability insurance protect against fundamentally different types of business risk, and most businesses that provide any kind of service or advice actually need both, not just one or the other.
What general liability typically covers
General liability insurance covers third-party claims of bodily injury, property damage, and certain advertising-related claims arising from your business operations. A classic example is a client slipping and falling at your office, or your work accidentally damaging a client's property during a service call.
General liability insurance generally does not cover claims related to professional mistakes or negligent advice — a contractor's general liability policy, for instance, wouldn't typically cover a claim that their design advice itself was flawed, only physical damage or injury arising from the work.
What professional liability typically covers
Professional liability insurance, sometimes called errors and omissions insurance, covers claims that your professional services, advice, or work product caused a client financial harm due to an alleged mistake, omission, or negligence — even if no physical injury or property damage occurred at all.
Why most service-based businesses need both
A consultant whose advice leads to a client's financial loss needs professional liability to address that specific risk, but still benefits from general liability if a client visits their office and is injured, or if their work somehow damages a client's physical property. These risks are genuinely distinct, and a single policy type typically doesn't cover both kinds of exposure.
- Identify whether your business risk includes physical interactions with clients or their property (general liability territory)
- Identify whether your business provides advice, designs, or services where a mistake could cause purely financial harm (professional liability territory)
- Assume both types of risk likely exist unless your business model clearly and entirely avoids one category
- Ask an insurance agent specifically how each policy's exclusions might leave a gap the other policy would need to fill
Frequently asked questions
Is professional liability the same thing as malpractice insurance?
Malpractice insurance is generally a specific term used for professional liability coverage in certain licensed fields, like medicine or law, but the underlying concept — coverage for professional errors and negligence claims — is essentially the same.
Can a client require me to carry one or both types of coverage?
Yes, many client contracts specify minimum required coverage types and amounts as a condition of the engagement, so checking contract requirements before assuming your existing coverage is sufficient is an important step.
