Your reality today
The patchwork is worse on this side of the contract.
As a sub, you don't pick the software — every GC does, and they all picked different ones. You end up running your business on the seams between them.
A dozen GC portals.
Procore here, a custom owner portal there, a third on Google Drive. Every login is different; every pay app form is different; every "where's your COI" thread is different.
Pay apps in Excel.
Your G703 lives in a spreadsheet you copy-paste every month, then re-type into whatever the GC requires. The math is right; the format is always wrong.
Certs slipping through.
OSHA expirations, GL renewals, WC dec pages — you find out one is lapsed when a project manager flags it on a Friday afternoon.
Crews on paper.
Timesheets faxed in from the trailer. Daily logs in a foreman's notebook. By the time the office sees what happened on a job, it's two days old.
What AOS does for you
One system of record. Every GC, every project.
AOS is your operating system. The GC's portal is just where you push the output. Stop letting their tooling dictate your workflow.
AIA G702 + G703 submit
Maintain your G703 once in AOS. Generate the GC-required format on submission — PDF, Excel template, or portal API push — so the math is yours but the format is theirs.
Conditional & unconditional waivers
51-jurisdiction statutory forms with Blue Notary RON when required. Waivers refuse to advance until notarized — no more "did you sign that yet?" emails.
Certs & insurance tracker
OSHA, EM-385, manufacturer certifications, GL, WC, auto, umbrella — all in one registry with 90/60/30/7-day expiration alerts and a one-click "send my COIs" link for any GC.
Foreman dashboard for your crews
Crew of the day with worker typeahead, geofenced timesheets, voice logs, equipment pinned at the site, NOAA weather. The same field tools the GCs we work with run.
AR aging that doesn't blink
Track every pay app from submitted → approved → paid, with retention release dates, statutory pay-when-paid status, and aging on every contract. Know who's slow before payroll runs.

Built for every seat at your trade
One platform, four tailored views.
From the owner who signs the bid to the foreman pouring at 6am, AOS gives every role the same record — with screens, alerts, and SLAs tuned to the work they actually do.
For the Subcontractor Owner / Executive →
Backlog, gross-margin by GC, bid hit-rate by trade, cash position, and the early-warning queue across every active job — without waiting for month-end close.
For the Sub Project Manager →
ITB inbox with GC documents pre-parsed, pay-app generation against the SOV, RFI/submittal tracking, and a CO log that ages by GC client — one record per project.
For the Sub Foreman →
Geofenced timesheets that survive cell-dead jobsites, voice-to-log daily reports, drawing markup from the field, and a crew-of-the-day view that ties to payroll.
For Sub Accounting →
Pay-app posting straight into the GL, retention rollforward by GC, lien-waiver lifecycle, AP automation against the PO and the budget, and 1099 prep without a spreadsheet.
Bidding to GCs, working for owners directly, or coordinating with design? AOS also fits commercial general contractors, owners and developers, and architecture firms on the same platform.
Run your trade on your software, not theirs.
30-minute walkthrough on a project you're actually bidding on. We'll show you the ITB inbox, the pay app, and the lien waiver flow — then you decide.
