Pay-app generation
Owner pay apps from the live schedule of values with approved change orders — math validated before billing.
For GC Accounting Teams
Pay app to the GL — without the retyping.
Construction accounting is a chain: budget to pay app, pay app to lien waiver, waiver to AP, AP to the GL. AOS keeps that chain on one job record so your team reviews instead of re-keying what the PM already approved.
Pay apps from the budget
Lien waivers gate AP
Retention updated each pay app
Tiered approvals before pay
Your reality today
Three platforms, one GL, your weekend.
PMs work in one tool. AP works in accounting. Lien waivers live in email or a third system. Month-end is stitching them together by hand.
Pay apps built by hand.
PM sends values; you re-key the continuation sheet and hope the change orders made it into this version.
Waivers don't stop payment.
Sub pay app arrives without the prior waiver. AP pays because checking both places is manual.
Retention lives in Excel.
Per-sub, per-job retention with milestone releases tracked in email — not a live balance sheet number.
GL posting is double entry.
Approved pay apps and AP get typed again into QuickBooks, Sage, or whatever you run.
What AOS does for you
Accounting on the same record as the PM team.
The budget is the source. Pay apps draw from it. Lien waivers gate AP. Retention updates automatically. Export to your GL when you're ready — AOS is not a replacement for your construction payroll vendor.

Tiered AP approval
PM → accounting → owner workflow on sub pay apps and vendor bills before money moves.
Lien waiver gating
Conditional and unconditional waivers tied to pay periods — held AP shows up as a queue, not a surprise.
Retention accounting
Per-project, per-sub retention on every pay app with milestone releases tracked across the portfolio.
GL export & migration
Pay apps, AP, and retention post to a full construction GL inside AOS. Export journals to CSV or Excel for your outside accountant; migrate history in from QuickBooks, Sage 300, Foundation, or Vista. Live sync with outside GLs is coming soon.
Blue Notary for waivers
Remote online notarization for waivers where your state requires it — we turn it on when you need it.
