A few thoughts...It has been suggested that we shop around for new insurance every two to three years. This applies to home, life, auto as well as your business. The valuation of your assets and equipment, corporate revenue, liabilities, etc. are fluid. You may think you have the best policy but one misstep by you and a failure to declare something can void your coverage. The other difficulty I see quite often is that your agent/broker is more focused about the insurance legalese and really has no idea what you do. Talk to other shops in your area and see how they manage their coverage. Possibly they have a lead on an agent/broker who truly understands what you do and can provide fare rates as well as ideas how to reduce or eliminate some unnecessary costs. Last thought, I find that if you go through a travel broker whether online or at an agency you will always find better travel options then if you give over priced airlines like AA a call direct. My experience anyway.
