Step 3Define what counts as proof of coverage.
A certificate of insurance is issued for information only. It shows what a policy looked like on the day the certificate was produced, and it does not change the policy. Your SOW should say what the certificate must show and how you will know if the policy changes.
For a certificate the contractor brings, check that the named insured matches the contractor, the policy dates cover the whole engagement, the limits meet your schedule, and the certificate holder and additional-insured fields are right. COI Review does these checks on ACORD certificates and sends only the exceptions to a person.
For a policy the contractor bought through 1099Policy, the policy record is attached to the engagement, and status changes such as a cancellation or an expiration are reported by webhook. Procurement does not need to ask for a new certificate to learn that coverage has ended.
