BuildProofBuildProof
For Subcontractors and Trade Partners

Submit a complete pay app. Keep proof you can stand on.

Check your pay application against the project's requirements before it goes up — the right waiver form, a current COI, your backup attached. And when you're paid, one tap records it; when you're not, that's on the record too.

What you get

  • A live checklist on every pay app: exactly what the GC, owner, or lender requires, checked before you submit
  • The right lien waiver at the right moment — conditional at submit, unconditional at payment, never backwards
  • Amanda flags a COI that's expiring or missing an endorsement and drafts the fix request for your broker
  • One tap confirms payment received — or records that it wasn't. Either way, the record protects whoever is right
  • Your billing, waivers, and backup in one place when a payment dispute ever comes
  • Free when a GC or owner invites you to their project

How it flows

1
Join by invite

Your GC invites you to the project. Profile, trade, insurance on file — minutes, not forms.

2
Bill the period

Enter your G703 values, attach photos and certs. The checklist shows every requirement and whose rule it is.

3
Submit complete

The checklist shows what's missing before you submit. Whatever it checks, you can fix before your GC ever sees the package.

4
Confirm payment

Money arrives, you tap once. It doesn't, you record that. The pass-through record follows the money, not the promises.

What changes on day one

What BuildProof checks, flags, and assembles from your first billing cycle.

Before you submit

Requirements checked up front

The checklist knows the project's requirements before you submit, so a missing waiver or an expired COI shows up on your screen instead of in a rejection email. Approval is still your GC's call.

Pre-picked

The right waiver for the moment

Conditional vs. unconditional, progress vs. final — matched to the payment moment, so you're not left to pick a form that signs away rights early.

Defensible record

Proof that follows the money

Your submissions, confirmations, and disputes are timestamped evidence — equally visible to whoever turns out to be right.
