If you manage a roster of subcontractors, you already know the problem: someone shows up on site, you realize their Certificate of Insurance expired three weeks ago, and now you're scrambling — either sending them home or taking on liability you shouldn't. It's a routine headache, and most GCs handle it the same way: spreadsheets, calendar reminders, and a lot of chasing.
There's a better way. This post explains what subcontractor COI tracking software does, what to look for, and how BuildSuiteCrew handles it.
What is a Certificate of Insurance (COI) and why does it expire?
A Certificate of Insurance is a one-page document that proves a contractor carries active liability insurance (and, where required, workers' compensation). It lists the policy holder, coverage types, coverage limits, and — critically — expiration dates.
COIs typically expire annually. A subcontractor who was fully covered when you hired them last spring may be working uninsured today if their policy lapsed and they didn't renew. If an incident happens on site while a sub is uninsured, that liability often falls to the general contractor.
This is why COI tracking is not optional — it's a basic risk management requirement for any GC managing multiple subcontractors.
The problem with spreadsheets and manual tracking
Most small and mid-size GCs track subcontractor documents in spreadsheets, email folders, or shared drives. The problems are predictable:
- No automatic alerts. You have to remember to check. Most people don't — until something goes wrong.
- Documents go stale. A PDF saved in 2024 doesn't automatically reflect a 2025 renewal.
- It doesn't scale. Managing 5 subs manually is annoying. Managing 20 is a part-time job.
- No audit trail. When a claim happens, "we think we had a COI on file somewhere" is not a defense.
What subcontractor compliance software should do
Good COI tracking software should handle the full lifecycle — not just storage:
- Document collection — subs upload their own documents, or you upload on their behalf
- Automatic expiry extraction — the system reads the expiration date from the document, not from manual entry
- Proactive alerts — you get notified before the document expires, not after
- Compliance dashboard — at a glance, you can see who is current, who is expiring, and who has a gap
- Audit trail — every document interaction is logged with a timestamp
How BuildSuiteCrew handles COI tracking
BuildSuiteCrew is a subcontractor compliance platform built specifically for general contractors. Here's how COI tracking works in practice:
Step 1: Build your roster
Add your subcontractors to your BuildSuiteCrew roster. If a sub isn't on the app yet, create an offline profile and upload their documents on their behalf — you don't have to wait for them to join.
Step 2: Request document access
For subs on the app, send a document access request. They approve with one tap and their COI, license, and W-9 are shared directly with you. BuildSuiteCrew reads expiration dates from the document automatically — no manual entry.
Step 3: Get alerts before anything expires
BuildSuiteCrew sends you an email alert as expiration dates approach. You're notified with enough lead time to follow up with the sub before they show up on site with a lapsed policy.
Step 4: See your full compliance status at a glance
The compliance dashboard shows every sub's document status: current, expiring soon, or expired. You can see exactly who is cleared to work and who needs action before you put them on a job.
Beyond COI tracking: what else BuildSuiteCrew handles
COI tracking is the most urgent compliance need, but it's not the only one. BuildSuiteCrew also tracks:
- Contractor licenses — state and trade-specific licenses with expiry alerts
- I-9 employment verification — required for any W-2 employee; BuildSuiteCrew validates content, not just storage
- W-9 forms — required for 1099 subcontractors before you can pay them
- Custom document types — anything else your contracts require (OSHA 10/30, drug test results, etc.)
It also includes a built-in e-signature workflow for subcontractor agreements — so you can send, sign, and store contracts without a separate DocuSign subscription.
Free for subcontractors
One reason COI tracking systems often fail is that subs resist using them. They don't want to pay for another tool, and they don't want to re-upload their documents to every GC they work with.
BuildSuiteCrew is free for subcontractors — always. Subs upload their documents once and share access with any GC in the network. They get expiry reminders for their own credentials so they're always ready for the next job. That removes the adoption barrier that kills most compliance systems.
How to get started
If you're managing 5 or more subcontractors and still tracking COIs in a spreadsheet, it's worth trying a purpose-built tool. BuildSuiteCrew has a 14-day free trial for general contractors — no credit card required to start.
