Frequently Asked Questions

What is commercial lines insurance?
Commercial lines insurance refers to property and casualty coverage designed for businesses rather than individuals. It includes policies like commercial property, general liability, workers compensation, business owner policies (BOPs), and specialty coverages such as professional liability and cyber insurance. These policies protect a business's physical assets, income, employees, and legal liability.
How is commercial insurance different from personal insurance?
Commercial policies are rated based on business classification, revenue, payroll, number of employees, and industry-specific risk factors — not personal factors like credit score or driving record. Commercial policies also tend to have more complex coverage forms, higher limits, and endorsements tailored to specific business operations. The claims process often involves more documentation and longer resolution timelines.
What commercial insurance does a small business need?
At minimum, most small businesses need general liability insurance and, if they have employees, workers compensation. Depending on the business type, you may also need commercial property insurance, commercial auto, professional liability, and cyber liability coverage. A Business Owner Policy (BOP) bundles property and liability coverage at a lower cost for qualifying small businesses.
How are commercial insurance premiums calculated?
Premiums are based on your business classification code, annual revenue or payroll, claims history, location, number of employees, and the specific coverage limits and deductibles you select. Your experience modification rate (for workers comp) and loss history heavily influence pricing. Working with an independent agent who understands your industry can help you find the most competitive rates without sacrificing coverage.
