Certificate of Insurance Tracking for Contractors
Collecting a certificate of insurance (COI) from each sub once isn't enough. Policies renew on different dates, and the sub who never got onto your tracker is often the one that costs you at audit. Here's a practical way to track sub COIs.
1. Start from payments, not from your certificate folder
Auditors typically work from who you paid. Each month, pull your vendor payment report and make sure every sub on it has a certificate on file. That catches the one-off crew someone paid without collecting paperwork.
2. Record the key fields for each certificate
- Named insured (legal name), and whether it matches the payee name
- Insurer and policy number for workers' comp and general liability
- Policy start and end dates
- Limits, compared with your own requirements
- Whether you're listed as certificate holder or additional insured, if your contracts require it
3. Check coverage dates against payment dates
A certificate only helps for the period it covers. Compare each payment date with the policy dates. Payments made after a policy expired are the gaps to fix.
4. Chase renewals before they lapse
Ask for an updated certificate about 30 days before each expiration. Many contractors hold payment until a current certificate arrives. Request certificates from the sub's insurance agent when you can, because a certificate is informational and doesn't by itself guarantee coverage (Insurance Journal on certificates vs. policy language).
5. Handle "no employees" subs on purpose
In Idaho, sole-proprietor owners and certain other owners are exempt from workers' comp for their own employment (Idaho Code §72-212), and contractor registration requires a certificate or a statement explaining why coverage isn't required (Idaho Code §54-5210). Keep that documentation, and ask your carrier what it accepts. Note why it matters: under Idaho Code §72-216, you can be liable for an uninsured sub's injured employees.
6. Keep an audit-ready file
At policy end, you want one file per sub with certificates, dates, exemption documents, and totals paid. That's what an auditor will typically ask for. See our free subcontractor audit checklist.
Spreadsheet or service?
A spreadsheet works if someone updates it every month. If that keeps slipping, Cleared to Pay does it for you: monthly payment-to-certificate matching, renewal chasing, and an audit-ready file, all by email.
