Pay app math validation
G702/G703 math validated against your live budget. Stored materials, retention, prior pay apps, change orders — checked automatically. Your team reviews exceptions, not arithmetic.
For Owner / Accounting Teams
Validate the pay app, gate the lien waiver, post the draw — on one record.
Owner-side accounting is the last gate before money moves. AOS turns the validation chain — pay app math, lien waiver match, retention release, draw posting — into one record instead of five inboxes.
Pay app math validation against budget
Lien waiver match before approval
Retention accounting per project
Draw posting tied to capital tranche
Your reality today
Pay app review is a five-app reconciliation.
Pay app PDFs from the GC, lien waivers from the title company, retention tracker in Excel, draw schedule in another spreadsheet, GL in your accounting platform. Your team is the integration.
Pay app math is checked by hand.
Stored materials, retention, COs to date, completed-to-date by line — your senior associate retypes the G703 into a spreadsheet to verify the math. Every month, every project.
Lien waivers don't reconcile to payments.
The title company tracks waivers in their system. The GC tracks pay apps in theirs. You hold payment when something's missing — and the missing thing is usually a subtier waiver no one's chasing.
Retention release is a fire drill.
50%, 75%, 100% milestone retention releases come at you sub by sub, project by project, with no central tracker. Half your team's month-end is the retention scramble.
Draws are still PDF assembly.
Pay app + waivers + sworn statement + photos + lender certification — assembled by your associate into the one specific format your lender wants. Five days. Every cycle.
What AOS does for you
Pay app, lien waiver, retention, draw — one record, one workflow.
AOS is the GC's pay app system and yours. The same G702/G703 they generate, you validate. The same waivers their subs send, you gate against. The retention tracker is live, the draw is one click.
Lien waiver gating
No pay app advances without unconditional waiver for prior period + conditional for current. Subtier waivers required where contract terms specify. Held payments surface as a queue.
Retention accounting + releases
Per-project retention liability live on every pay app. Milestone-based releases (50%/75%/100%) tracked across every project. Auditor gets the workings.
Lender draw package assembly
Pay app + waivers + sworn statement + photo evidence + lender certification → one signed PDF per draw. Per-lender format (Wells, Truist, PNC, Eastern, MUFG) supported.
GL posting + cap interest
Pay app approval posts to your GL of choice. Capitalized interest accrual tied to draw cadence, per loan tranche, with workings the auditor can re-perform.
Audit confirmation packs
Subcontract list, retention liability, lien releases, CO log, draw history — one button per project per quarter. The auditor's confirmation pack in their preferred format.
