The problem
An uninsured sub can cost you at the year-end audit
When a subcontractor's insurance lapses, your insurer can charge you for their work at the year-end audit. Chasing certificates by email and tracking dates in spreadsheets misses things. TradeProof keeps every certificate and W-9 current, and tells you before something expires.
Example (illustrative): a sub's policy expires on a Friday. On Monday the crew is already on site, and the certificate is still missing.
Estimate with an example 8% audit charge on payments to uninsured subs. Your insurer's rate may differ.
Rules vary by state and insurer. TradeProof is not legal or insurance advice.
Possible audit charge
$120,000 paid to subs who couldn't prove coverage. TradeProof shows this number on your dashboard and helps you bring it to zero.
Trust
The AI reads. People decide when it matters.
It reads what it can
The AI pulls limits, dates, the insured name and W-9 details from each upload.
It checks against your rules
Each certificate is compared with the requirements for that trade.
It asks a person when unsure
Anything that doesn't pass cleanly waits in a review queue. Nothing is approved on a guess.
You can always open the original document and check it yourself before you approve.
How it works
Three steps, no training
Add your subs
Paste a list of emails, add them one by one or import a spreadsheet.
They upload their documents
Each sub gets a secure link — in English or Spanish — to upload their certificate and W-9 from a phone or computer. No account needed.
We track everything and alert you
TradeProof reads each certificate, checks it against your requirements and reminds subs before coverage expires.

See the money at risk
An estimate of what uninsured subs could cost you at the audit, on your dashboard.
English and Spanish
The upload page and every email to your subs speak their language.
Plain-language “what’s missing”
Subs see exactly what to fix, like “your general liability limit must be at least $1,000,000”.
Automatic compliance check
Limits, dates, additional insured and waiver checked against your requirements.
Hold payment
Mark a sub's payments on hold until their paperwork is fixed.
Set up in minutes
Add your subs, set your insurance requirements and send the first requests in one sitting.
Built for real crews
Your subs upload from their phone — in English or Spanish.
No app to install and no account to create. Each sub gets a secure link, sees exactly what's missing in plain words, and can snap photos of a paper certificate. Every reminder speaks their language.
- Photos become one clean PDF automatically
- “What’s missing” written for the sub, not for lawyers
- Reminders before anything expires

FAQ
Questions
+What is a COI?
A certificate of insurance (COI) is a one-page summary of a company's insurance: who insures them, the policy limits and the dates. General contractors collect one from every subcontractor.
+Why does it matter at the audit?
At the end of the policy year your insurer audits the work you paid subcontractors for. If a sub had no valid insurance, the insurer can charge you as if they were your own employees.
+Is my data secure?
Documents are stored in private, encrypted storage and are only reachable through short-lived links. W-9 tax ID numbers are encrypted, and only the last 4 digits are shown. You can turn on two-step verification for your login.
+Can I cancel anytime?
Yes. Plans renew monthly or yearly and you can cancel from the Billing page at any time. Paid plans come with a 30-day money-back guarantee.
+Do my subcontractors need an account?
No. They get a secure upload link by email and can upload from their phone.
+Does it work in Spanish?
Yes. The upload page and the emails to subcontractors are in English or Spanish. Each sub picks their language, and you always see everything in English.
+Can my subcontractor's insurance agent send the certificate?
Yes. From a sub's page you can email their agent your requirements and a secure upload link. The agent uploads the certificate directly, with no account needed.
+Who handles sales tax?
Our payment provider, Paddle, is the merchant of record. It calculates and collects any sales tax on your subscription and sends the receipts.
+What happens to my data if I cancel?
You can download everything (documents, subcontractors and activity) as a ZIP from Settings at any time. If you ask to delete your account, it is removed after a 30-day grace period, so you can change your mind.
Who's behind TradeProof
A small team that answers fast.
TradeProof is built by Caellum, a small software studio based in Brazil, working with contractors across the United States.
A note from the founder: “I watched a general contractor lose a weekend hunting down certificates before an audit. TradeProof exists so that never happens to you.”
