What is an average price for liability insurance for small businesses?

Commercial Liability insurance is based on the industry that the company is involved in and it usually is based on payroll. Some industries are based on other factors but in most cases its payroll. For this reason, I can't really give you an accurate number for this and no one else can either. If you don't have any employees except yourself, and you have a business that doesn't provide any real extraordinary risk factors, I guess you could estimate your CGL at between $500-$1000 per year.
