What is it: Workers Compensation covers an employee's lost wages and the cost of resulting medical treatment if they suffer a work-related injury or disease. It also covers services needed to help the employee recover and return to work.

Why get it: Workers Compensation coverage is mandatory in most states. The number of employees after which it's required differs by state, but you will generally need coverage once you have employees.

What is it: This policy protects your business in case of third party claims, such as bodily injury or property damage. For example, the common "slip-and-fall" claim would be covered by your General Liability policy.

Why get it: General Liability insurance is often considered to be the core coverage, particularly for businesses that regularly physically interact with customers or sell physical goods. In addition, many businesses have a contract, like a loan or a lease, requiring that they have this coverage.

What is it: Umbrella insurance offers excess liability protection in the case that your General Liability, Commercial Auto Liability, and/or Employer's Liability coverage is insufficient. It essentially acts as a "back-up" plan, providing additional financial protection in the case that your business faces a particularly large claim that exceeds a single policy's limits.

Why get it: This policy can be particularly valuable for a business that faces a variety of risks and has multiple liability policies.
