As a professional with extensive knowledge in your area of expertise, you always try to dot all the Is and cross all the Ts in the services you provide to your clients. But no one is perfect. Sometimes, even you can make a mistake. And if a disgruntled client believes your errors have cost them money (even if it’s not true), you might be sued. The cost to defend your company could be a serious drain on your resources. Fortunately, professional liability insurance can provide a level of protection.
