Commercial insurance provides coverage for businesses against a variety of risks and losses. There are four main types of commercial insurance: general liability insurance, which protects against claims of negligence and injuries; product liability insurance, which covers losses from defective products; professional liability insurance, also known as errors and omissions insurance, which protects against malpractice and negligence in providing services; and commercial property insurance, which covers losses and damage to business property from events like fire or storms. It is important for businesses to have adequate insurance to protect against financial losses that could devastate the company.
