COI stands for Certificate of Insurance. This document issued by your insurance company or broker and is used to verify the existence of insurance coverage. It will list the effective dates, type and amount of coverage list on your policy. Your customer will require you to submit certificates of insurance to them through systems like ISNetworld, Avetta, and PEC Premier that proves that you and your employees will be covered by insurance if any damages or injuries occur. COIs that are not up to date or improperly submitted COIs are one of the most common reasons for your account grade to be reduced. Our Annual Account Maintenance program can keep that from happening.
