Automate construction billing due diligence in seconds. Instantly cross-check AIA G702/G703 math, enforce 12-state statutory waiver compliance, and verify ACORD 25 insurance endorsements — before checks are cut.
Dual-Mode Document Privacy — Temporary processing and retry storage for public & pack audits; encrypted server draw ledgers & vaults for commercial projects.
From upload to lender-ready certificate in under 30 seconds.
Drag and drop your draw documents into the 2-layer packet grid: Layer 1 (Current Lien Waiver [Required], Invoice, AIA G702) and Layer 2 (Prior Unconditional Waiver, ACORD 25 COI). Direct encrypted uploads up to 50 MB per document. Documents are transmitted for processing; project-backed audits retain structured results under workspace permissions.
Gemini multimodal AI extracts unstructured financial entities from all draw documents simultaneously. Deterministic TypeScript engines execute mathematical reconciliations — verifying AIA Line 8 ↔ Net Due ↔ Current Waiver, AIA Line 7 ↔ Prior Unconditional Waiver clearance, statutory notary jurats, and sub-tier supplier exposure.
Get a structured Approved or Flagged verdict with a full discrepancy log. Download a tamper-evident SHA-256 PDF certificate recording the checks performed for your project records.
Every check we run, broken down by document type across our 2-layer packet architecture. Upload your Current Lien Waiver plus any supporting documents (Invoice, AIA G702, Prior Unconditional Waiver, ACORD 25 COI) to run an audit.
Eliminate multi-page Schedule of Values subtotal traps and prevent orphan second-tier materialman mechanics' liens before loan disbursements.
Column G Terminal Grand Total == Line 4
Commercial subcontractors frequently submit 5 to 30-page G703 continuation sheets with conflicting per-page running subtotals. WaiverAudit skips intermediate noise and deterministically verifies the terminal cumulative Grand Total against G702 Line 4 within ±$0.01 tolerance.
2nd-Tier Mechanics' Lien Defense
When a trade contractor itemizes major supply house materials or equipment rentals, owners face direct lien exposure if those vendors are unpaid. WaiverAudit detects material charges and provides a progressive drawer to collect and clear secondary releases.
WaiverAudit enforces state-specific statutory requirements for lien waivers. Each state engine detects missing language, incorrect form types, and non-compliant notary clauses.
Jurisdictions outside these 12 states are audited without statutory enforcement using Generic mode.
Construction pay applications contain confidential financial data. WaiverAudit was architecturally engineered with Dual-Mode Document Privacy.
Public, free, and pack audits use temporary processing and retry storage with deletion attempts after completion and expiry cleanup. Commercial project tiers maintain encrypted PostgreSQL draw ledgers and optional AES-256 Cloudflare R2 vaults with automated 30-day auto-purge for raw PDFs.
Completed audits produce PDF certificates carrying the server audit hash and recorded checks. The hash supports tamper-evident records; it does not establish lender endorsement or payment.
Every company tier includes unlimited named team members with individual logins, role-based permissions, project assignments, and attributable audit records. Personal device controls are separate from team access.
