A COI File alternative with real verification depth
COI File offers inexpensive certificate storage and expiry reminders. As a filing cabinet with an alarm clock, it's priced fairly.
CoverWarden is a compliance system: certificates are parsed and checked against your requirements, endorsement pages are read with evidence quoted, non-compliance is explained in plain language, and renewals chase themselves — vendor and agent both.
