COI tracking sounds boring until a vendor’s insurance expires right before urgent work. Then it becomes everyone’s problem. A clean COI process can save hours of email chasing and reduce last-minute risk.
Quick answer
The biggest COI tracking mistakes are not recording expiration dates, not checking additional insured wording, keeping COIs only in email, not separating pending vendors from approved vendors, and waiting until the day of work to review paperwork.

Common COI tracking mistakes
- Saving certificates only in email threads.
- Not entering expiration dates into a tracker.
- Not setting renewal reminders 30, 15, and 7 days before expiration.
- Not checking whether the vendor name matches the contract or W-9.
- Not checking required coverage types.
- Not documenting what is missing.
- Not assigning one person to own follow-up.
- Approving vendors verbally without updating the tracker.
- Mixing old certificates with current certificates.
- Not keeping a simple audit trail of requests and responses.
Better COI workflow
- Collect COI before work is scheduled.
- Save the file in a named vendor folder.
- Enter expiration date and coverage notes into a tracker.
- Mark missing items clearly.
- Send one clean request email.
- Set the next follow-up date.
- Review expiring COIs weekly.
- Archive old certificates instead of deleting them randomly.
Reminder schedule
| When | Action |
|---|---|
| 30 days before expiration | Send friendly renewal request |
| 15 days before expiration | Send second reminder and flag account |
| 7 days before expiration | Escalate internally if vendor is still active |
| Expiration day | Mark vendor expired/pending review until updated COI arrives |
Simple internal note
Example
Vendor COI expires on [date]. Renewal requested on [date]. Missing updated certificate and additional insured wording. Vendor should remain pending until updated paperwork is received.

Final thought
COI tracking does not need to be complicated. It needs to be visible, current, and owned by someone. A basic tracker used consistently beats a perfect system nobody updates.
