Business Insurance Basics for Small Companies
Small business insurance is a set of separate products that people talk about as though it were one. Understanding which risk each covers is most of the work, because the common failure is not underbuying a policy — it is not knowing a category exists.
General liability is the foundation and the most widely held. It covers third-party bodily injury and property damage: a customer slipping in your premises, your employee damaging a client's equipment. It does not cover your own property, your own employees' injuries, or mistakes in your professional work.
The gap that closes service businesses
Professional liability — also called errors and omissions, or malpractice in some fields — covers claims that your advice or work was negligent or inadequate. General liability explicitly excludes this.
So a consultant whose recommendation costs a client money, an accountant who misses a filing deadline, an architect whose specification proves inadequate, an IT contractor whose migration loses data: none of these are general liability claims. They are professional liability claims, and a business without that cover pays defence costs from its own funds even when the allegation is ultimately unfounded. Defence costs alone frequently exceed the settlement.
Workers' compensation is not discretionary
Almost every US state requires workers' compensation once you have employees, with thresholds and exemptions varying. Texas is the notable outright exception. Penalties for operating without it where required are severe, and in several states officers can be held personally liable.
The classification of your workforce matters enormously to the premium, and misclassification is a common audit finding. So is treating workers as independent contractors when the working relationship does not support it — a determination made by the facts of the arrangement, not by what the contract calls it.
Commercial property and the business interruption question
Commercial property covers your building, equipment, inventory and fixtures. The important choice is the same as in home insurance: replacement cost or actual cash value. For equipment that depreciates quickly, the difference at claim time is large.
Business interruption cover, usually added to property, replaces lost income while you cannot operate. This is the coverage that determines whether a fire is a setback or an ending. Note that it generally requires physical damage to trigger — a point litigated extensively after 2020, when most claims for pandemic closure failed precisely because there was no physical loss.
Cyber cover has stopped being optional
Any business holding customer data, taking card payments or relying on connected systems has cyber exposure. Standard general liability policies exclude data breaches almost universally now.
Cyber policies split into first-party cover — your own costs: forensics, notification, credit monitoring, business interruption, and in many policies ransom payments — and third-party liability for claims by affected customers. Small businesses are targeted heavily precisely because their defences are weaker, and the regulatory notification obligations after a breach apply regardless of company size.
Commercial auto and the personal policy trap
If employees drive for work, personal auto policies frequently exclude business use. An employee running deliveries in their own car may have no valid cover at all, and the claim will land on the business.
Hired and non-owned auto liability addresses this and is inexpensive. It is one of the most commonly missing coverages in small firms that do not operate a formal fleet.
Buying it sensibly
A Business Owner's Policy bundles general liability with commercial property at a lower combined price and suits most small, low-hazard operations. Add professional liability if you sell expertise, cyber if you hold data, workers' comp if you have staff, and commercial auto if anyone drives.
Two practical points. First, tell the insurer accurately what you actually do — misrepresenting operations to get a better rate voids cover exactly when you need it. Second, review annually against how the business has changed, because coverage bought for a two-person operation rarely fits a twelve-person one. Growth is the most common cause of quiet underinsurance.
