How subcontractor COI tracking software actually works — and why it beats chasing people by email

Most general contractor teams manage subcontractor COIs the same way: a shared spreadsheet, an inbox full of PDF attachments, and someone whose job it is to remember who needs to renew next month.

That system breaks under load. It breaks when someone's on vacation. It breaks when a sub's policy quietly lapses six months into a project and nobody notices until something goes wrong.

Subcontractor COI tracking software replaces that process with a workflow that runs itself. Here is exactly how Send The Proof works.

Step 1: Add a vendor and set what you need

You add the subcontractor — name, contact, scope. You set what documents they need to provide: COI, W-9, contractor license, whatever your project requires.

Takes about two minutes per vendor.

No spreadsheet column. No shared folder. Everything lives in the vendor's record from day one.

Step 2: The vendor gets a link — not a login

This is the part that actually changes response rates.

Your sub gets a secure upload link. They click it. They upload their certificate of insurance. Done. No account to create. No portal password to reset. No platform they have to learn.

Their agent can use the same link and submit directly — which means the COI comes straight from the source, not from a PDF the sub forwarded from six months ago.

Subs respond to this. They ignore portals.

Step 3: The system tracks every expiration date

When a COI comes in, the expiration date goes into the system.

You do not have to log it. You do not have to set a calendar reminder. You do not have to check the spreadsheet every Monday to see who is coming up.

Thirty days before a policy expires, the sub automatically gets a renewal request. If they do not respond, follow-up reminders go out. You see the status — compliant, expiring soon, or blocked — on a dashboard that updates in real time.

You stop chasing. The system chases for you.

Step 4: You have a compliance record, not just a pile of files

Every upload, approval, reminder, and rejection is timestamped.

When an owner, insurer, or attorney asks what you had on file and when, you pull the audit trail — a clean, exportable record of every compliance action across every vendor.

That is the difference between a compliance program and a folder of PDFs.

What it costs vs. what it prevents

Send The Proof is free for your first five vendors. No credit card. No setup fee for your subs.

The paid plan is $29.95 a month.

A single workers' comp claim from an uninsured sub can run into six figures before attorneys get involved. A lapsed COI on a Texas data center build — where workers' comp is optional and damage caps don't apply to non-subscriber subs — can mean unlimited exposure.

The math is not complicated.
