Do my subcontractors have to pay or download an app?

No. Subs are always free. They open a link, take a photo of their certificate or upload the PDF, and they're done. They can also text a photo or email it to coi@subproof.co.

What happens when a policy is about to expire?

Starting 30 days out, SubProof reminds the sub by email, text and phone call, more often as the date gets closer. You see an expiring-soon flag on that sub and can get a text alert on your phone.

Can I try it before paying?

Yes. SubProof is free for up to 3 active subs with every feature included, no credit card needed. Paid plans start at $29 a month for 10 subs.

For general contractors and builders

Stop chasing certificates. Know every sub is insured.

Q: How does SubProof catch fake certificates?

SubProof looks up the insurance agency through its license record instead of trusting the phone number or email printed on the certificate, then asks the agent to confirm the policy. The agent can confirm, correct a field, or say the sub isn't their client.

We collect your subs' certificates, verify them with the real agent, and chase renewals for you.

Sound familiar?

An uninsured sub becomes your problem

The audit bill

No valid certificate at audit time, and you pay their premium.

The claim that comes back to you

Their policy lapsed last month. Now the claim is yours.

The certificate that isn't real

Certificates are easy to fake, and the "agent" is often the sub.

The endless chasing

"Can you resend your COI?" Every job, every renewal.
