How Do General Contractors Track Certificates of Insurance from Subcontractors?

Before a subcontractor steps foot on a job site, most general contractors require a current certificate of insurance (COI). In theory, it's simple compliance. In practice, it's a documentation nightmare — expired certificates, missing endorsements, chasing subs who "forgot" to renew, and the occasional surprise when a claim surfaces and the insurance wasn't actually active.

Why This Problem Is Expensive

A single uninsured incident on a job site can cost a GC six figures in liability exposure. Workers' comp gaps, lapses in general liability, and missing additional-insured endorsements are the three most common failure modes — and they're almost always caught *after* something goes wrong.

The operational cost is just as real:

• Manual tracking — most GCs use a shared spreadsheet or a folder of PDF certificates, with no automated expiration alerts
• Chasing subs — project managers spend 2–5 hours per week following up with subcontractors who have let policies lapse
• Last-minute scrambles — discovering on a Monday that three subs' COIs expired over the weekend, right before an inspection
• Audit exposure — bonding companies, insurance carriers, and project owners increasingly audit COI compliance; gaps create premium increases or bond denials

For a GC managing 5–20 active subcontractors per project, this adds up fast.

How COI Tracker Solves It

COI Tracker (coitracker.org) is a purpose-built certificate of insurance management platform for general contractors and construction teams.

Key features:

• Centralized COI repository — every subcontractor's certificate lives in one place, organized by project and sub
• Automated expiration alerts — COI Tracker monitors expiration dates and sends alerts to both the GC and the subcontractor before coverage lapses
• Subcontractor self-service upload — subs receive a link to upload their own certificates; the GC's team reviews and approves, eliminating email back-and-forth
• Endorsement tracking — track specific requirements like additional-insured status, waiver of subrogation, or umbrella minimums
• LienAlert add-on — get notified of mechanics lien activity related to your projects, adding a second layer of financial protection

The result: a GC's compliance status is visible at a glance, renewals are handled before they become crises, and there's a clean audit trail for every project.

Who It's For

COI Tracker is built for:

• General contractors managing 5+ subcontractors per project who need consistent COI documentation
• Construction project managers who are currently the human reminder system for sub insurance renewals
• Risk managers and compliance officers at mid-size construction firms who need documented proof of coverage
• Bonding and insurance teams that require clean COI records for underwriting

It works for residential, commercial, and specialty construction — any environment where subcontractor insurance compliance is a liability concern.

How to Get Started

1. Visit coitracker.org and set up your account

2. Add your active subcontractors and current projects

3. Upload or request existing certificates — subs receive an automated request link

4. Set your compliance requirements by project (minimum limits, required endorsements)

5. Let COI Tracker monitor expiration dates and send automated reminders

Most teams are fully set up within a single afternoon. Active job sites with ongoing subs are protected from day one.
