AI pay-application verification
Every line.
Every dollar.
Verified.
CertPay reads a construction pay application - G702, G703, invoices, change orders, lien waivers - checks it against the contract baseline and payment history, and flags every discrepancy with a citation back to the source. You approve, reduce, or reject each line in minutes, not days.
No credit card required. Launch customer: Procedeo.
Seven checks on every package
Deterministic math runs as pure code; judgment calls use Claude with vision and structured citations - every finding points back to the exact page it came from.
Previous + this period + stored ties out on every G703 line and every column total.
Every billed dollar traced to an invoice, delivery ticket, or receipt - or flagged.
Billed COs verified against the approved register: amount, status, schedule of values.
Conditional vs unconditional, through-dates, execution - read like a legal reviewer.
Cross-application cumulative tracking catches double billing a single pay app can't show.
Required documents present before a package ever reaches your reviewer's desk.
Subcontractor support ties back to each GC line - progress %, retainage, and amount - with match memory.
How it works
Drop the pay-app package - PDF, spreadsheet, or scans. Extraction starts immediately.
Seven checks run against the project baseline, CO register, and cumulative billing history.
Review cited findings, disposition each line, and record the decision - fully audited.
Verifying a 300-page draw package in minutes
Pilot draw packages aren't tidy 20-page PDFs. They're 300-page stitched bundles of cover sheets, continuations, dozens of sub invoices, and scans. Handling them well is a systems problem, not a prompt.
Read →The arithmetic trap: why humans miss the math that matters
Everyone checks the G702 bottom line. Almost nobody checks whether it actually equals the sum of the G703 continuation. The errors that survive are the ones nobody bothers to verify - because verifying them is tedious, exacting, and unrewarding.

The tools exist. The talent exists. The bottleneck isn't technology - it's the gap between how software is sold and how construction finance is actually practiced, on site, under deadline.

Stop hand-checking spreadsheets against a stack of PDFs. Let CertPay catch what a single pay app can’t show you - and hand your reviewer a clean, cited packet.
