A framing crew's GL lapsed three weeks ago and nobody noticed. If they drop a bundle through a finished ceiling, that's your claim now. SubProof keeps every subcontractor's certificate, endorsement, and lien waiver on one board, chases the ones that expire, and keeps the proof. Built for general contractors and small builders.
Ask it the way you'd ask your PM — "which subs are working uninsured right now?" — and get the answer straight from your records. Works with AI helpers like Claude and ChatGPT, if your office uses them.
A COI on file means nothing if you're not named as additional insured. Track the endorsements that actually transfer risk — additional insured, waiver of subrogation, primary and non-contributory — separately from the certificate itself.
Conditional waivers before payment, unconditional after — tracked per sub per draw, so a final payment never goes out against a missing waiver.
Requests at 30, 10, and 3 days before expiry go to the sub and their agent, so you're not the one writing the fourth email about a certificate.
Who was asked, when, how many times, and what arrived — exportable per sub or per job, so an insurer's request after a loss is a download, not a scramble.
One uninsured sub on a loss becomes your claim. Builders running 10+ concurrent jobs from $99/mo.
