What is it: This policy, common in the professional services industry, helps to protect your business if a client believes they've suffered a loss due to an error or omission on your part.

Why get it: Your business may have contracts with clients or partners that require E&O coverage, provide a "warranty or guarantee," or have clauses that require you to "indemnify or hold harmless" your clients. If so, E&O coverage is often recommended. This coverage is also commonly recommended for any businesses providing advice related to legal or financial matters.

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: This policy protects the business's physical assets and is appropriate whether you own or lease your space. Keep in mind that this policy will only offer protection in the case of covered events. If you need protection for certain scenarios, such as floods or earthquakes, you may need additional coverage.

Why get it: If you have a mortgage or a lease, you may be required to have property insurance. Even if you are not, this is the best way to protect the building you are in and the business property you have in case of a natural disaster or some other accident.

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: Commercial Auto insurance provides coverages such as liability, collision, comprehensive, medical payments and uninsured motorist coverage.

Why get it: Any vehicle on the road must be insured, and any incidents that occur while a vehicle is being used for business purposes may not be covered by a personal auto policy. That's why it is so important to make sure you have Commercial Auto insurance for any vehicles owned by the business.

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.
