Quick answer
Create a COI expiration calendar with vendor name, policy dates, certificate holder needs, renewal reminder dates, and proof of follow-up.

Final thought
The best COI system is boring. It reminds you early, shows what is missing, and keeps proof of follow-up in one place.
Need vendor paperwork cleaned up?
