What Is COI Tracking?
COI tracking is the process of collecting, verifying, storing, and monitoring certificates of insurance from subcontractors and vendors — so you know their coverage is active before work starts, and before it lapses during a project.

What is a certificate of insurance?
A certificate of insurance (COI) is a one-page summary document issued by an insurance agent or broker that confirms a policy is in place. It lists the policyholder's name, the insurance company, the coverage types (general liability, workers' comp, commercial auto, umbrella), the coverage limits, and the policy expiration dates.
GCs and property managers request COIs from every subcontractor and vendor before they start work — as proof that those parties carry the minimum insurance required by the contract.
Important limitation: A COI proves insurance existed when the policy was issued. It does not confirm the policy is still active today, that premiums are current, or that the contractor's license is in good standing. Ongoing tracking is necessary to catch lapses between renewal cycles.
What does COI tracking involve?
Managing certificates of insurance is more than filing PDFs. A complete COI tracking process covers five things:
Collection
Requesting and receiving COIs from every sub before they start work — and again each time a policy renews. This is where manual workflows break down: email threads, missing attachments, and chasing subs who don't respond.
Verification
Reviewing the COI to confirm the named insured matches your contract, coverage types and limits meet your requirements, your company is listed as certificate holder (and additional insured where required), and expiration dates extend through your project timeline.
Storage
Keeping COIs organized and retrievable — by subcontractor, by project, and by date — so you can pull them up during an owner audit, insurance broker renewal, or incident investigation.
Expiration monitoring
Tracking every policy's expiration date and sending renewal reminders before policies lapse. Without automated alerts, coverage gaps are typically discovered only after an incident — when it's too late.
Renewal collection
When a policy expires, re-requesting the updated certificate and confirming the new one meets your current requirements. This cycle repeats for every sub on every policy line, every year.
Why managing certificates of insurance matters
When a subcontractor causes property damage, injures a worker, or has an incident on your job site, the first question your insurance broker asks is: "Was their policy active?" If you can't produce a current COI — or if the policy had lapsed — you may be responsible for costs that should have been covered by your sub's insurer.

Beyond liability exposure, many general contracts and owner agreements require GCs to maintain current COIs on file for every sub on a project. Failing to produce them during an audit can delay payment applications or trigger contract penalties.
Manual COI tracking vs. COI tracking software
Most GCs start tracking COIs in a spreadsheet. For fewer than 10 subs on a single project, a spreadsheet is workable. As the roster grows — or projects multiply — the manual approach breaks in predictable ways.
| Task | Manual / spreadsheet | COI tracking software |
|---|---|---|
| Collect COIs from subs | Email chase, hope they respond | Magic link — sub uploads in 2 min, no login |
| Extract coverage dates & limits | Manual data entry, typos possible | AI reads the PDF automatically |
| Expiration alerts | Calendar reminders you set manually | Automated at 90/60/30/7 days to you & sub |
| Renewal collection | Start the email chase again | Renewal upload link included in alert |
| Compliance report for owner | Export and clean up spreadsheet | PDF or CSV in one click |
| Contractor license check | Manual state database lookup | Automated against TX, FL, CA, WA & OR |

How to manage certificates of insurance: a practical system
Whether you're using software or a spreadsheet, a repeatable COI management process has three phases:
Phase 1 — Onboarding (before work starts)
- Set coverage minimums for the project (GL, WC, auto, umbrella limits)
- Request COI, W-9, and any trade-specific license documentation from the sub
- Verify named insured, additional insured status, limits, and policy dates
- Verify contractor license status against your state's licensing database
Phase 2 — Monitoring (during the project)
- Track expiration dates for every coverage line (GL, WC, and auto often renew at different times)
- Send renewal reminders at 90, 60, 30, and 7 days before each expiration
- Flag any sub whose coverage lapses before they renew — don't let them on site until reinstated
Phase 3 — Renewal (when policies expire)
- Re-request updated COI from the sub's agent or broker
- Re-verify coverage limits still meet your current project requirements
- Update your records and reset the monitoring cycle
What is insurance tracking software?
Insurance tracking software — also called insurance compliance management software, a COI tracking system, or a contractor tracking solution — is a category of software that automates the collection, verification, storage, and expiration monitoring of certificates of insurance from subcontractors and vendors. COI tracking is the most common use case within this broader category.
The difference between "insurance tracking" and "COI tracking" is mostly vocabulary. Insurance tracking software is the term used in searches that start at the problem ("I need to track my subs' insurance") rather than at the solution ("I've heard of COI tracking software"). The underlying workflow is the same.
| Term | What it means |
|---|---|
| Insurance tracking software | Generic term for tools that track insurance documents from vendors or subs — COI tracking is the primary use case in construction |
| COI tracking software | Specific term used in construction and property management — focuses on ACORD 25 certificates from subcontractors |
| Insurance compliance management software | Broader framing that includes policy verification, license checks, and compliance reporting — not just document storage |
| Insurance tracking system | Often used interchangeably with COI tracking software — emphasizes the systematic, repeatable nature of the process |
| Contractor tracking solution | Broader category that includes COI tracking alongside license verification, W-9 collection, and compliance reporting |
TrackMyVendor is a contractor tracking solution that covers the full compliance workflow: collecting COIs via magic link, parsing them with AI, verifying contractor licenses against state databases, collecting W-9s in the same workflow, and sending automated expiration alerts at 90/60/30/7 days. It handles everything in a single dashboard rather than requiring separate tools for each document type.
When comparing insurance tracking software options, the meaningful differentiators are: Does it automate document collection (or just store what you manually upload)? Does it verify the underlying license, not just the COI? Does it send dual alerts to both you and your sub with a renewal link attached? And can subs submit documents without creating an account?
