Commercial insurance protects a business against certain losses covered by its policies. The right mix depends on what the business does, its employees, property, vehicles, contracts, and state law. General liability coverage does not insure every business risk.
Compare policies by actual work performed, exclusions, limits, deductibles, and the insurer’s claims process. An inexpensive policy is not useful when it excludes the work your company performs.
Main types of business insurance
General liability insurance can cover certain third-party injury, property damage, and related claims. Commercial property insurance can address covered damage to business buildings, equipment, or inventory.
Professional liability, often called errors and omissions coverage, may apply to certain claims about professional services. Workers’ compensation covers eligible work-related employee injuries under applicable state laws. Commercial auto insurance addresses vehicles used in business.
The NAIC guide to small business insurance explains how these coverages differ.
Compare the specific policy terms
| Coverage | What to review |
|---|---|
| General liability | Bodily injury, property damage, and exclusions |
| Property | Buildings, equipment, inventory, valuation |
| Professional liability | Service errors and policy triggers |
| Workers’ compensation | State obligations and eligible workers |
| Commercial auto | Company vehicles and covered business use |
| Cyber | Covered events, costs, limits, and duties |
| Business interruption | Covered causes of shutdown and waiting periods |
| Umbrella | Additional liability limits and underlying requirements |
A policy may exclude professional mistakes even when it includes general liability. A company using personal vehicles for work may need coverage that is not part of a standard personal auto policy.
Business owner’s policies and package coverage
A business owner’s policy, or BOP, often combines certain general liability and commercial property coverage for eligible smaller businesses. It may be convenient, but it does not automatically include workers’ compensation, commercial auto, or professional liability.
Not every business qualifies for a standard package. A contractor, manufacturer, consultant, and retail store can have very different risks.
Read each section rather than assuming one policy covers the whole operation.
How limits and deductibles work
A policy limit is the most an insurer will pay for a covered category or period under the contract. Deductibles are amounts the business may need to pay when a covered loss occurs.
For a hypothetical covered property claim of $20,000 with a $2,000 deductible, the insurer might pay $18,000, subject to valuation, limits, and exclusions. This is only a calculation example, not a promise of how any real policy settles.
Compare per-occurrence limits and aggregate limits where relevant. A high limit may still be of little use when a claim falls within an exclusion.
Contracts and certificates of insurance
A client or landlord may require proof of insurance. A certificate of insurance can show certain policy information, but it does not itself change the policy’s coverage or grant rights not in the contract.
Ask the insurer or agent whether additional insured status, waivers, or specific endorsements are required by the contract. Do not promise a client that a certificate alone provides extra coverage.
Check whether subcontractors must carry their own insurance and how their work affects your policy. The answer depends on your business, contract, insurer, and state law.
Cyber risks and lost income
Cyber coverage can vary in what it pays for after a covered incident. Some policies include response services, while others set strict notice and security conditions. Read the actual coverage triggers.
Business interruption coverage often requires a covered cause of property loss and may include waiting periods. It does not automatically pay for every drop in revenue or a business closure.
Compare exclusions before treating a policy name as proof that a risk is covered.
Choosing policies for your business
List the claims that could arise from actual operations: customer injuries, damage to client property, employee incidents, service mistakes, vehicles, stolen equipment, or a data breach.
Then check state requirements and contractual obligations. An insurance agent can help identify policies, but compare written terms and licensing rather than relying solely on a verbal summary.
If a quote is unusually low, ask what was removed or excluded. A lower premium can reflect narrower protection or a larger deductible.
When general liability alone is not enough
A contractor may need tools coverage and workers’ compensation beyond liability. A consultant may need professional liability. A store may need inventory and business property protection. A business with vehicles may need commercial auto.
These are examples rather than automatic legal requirements. State law and policy forms determine what must be purchased and what is covered.
