For Subcontractor Accounting Teams

One cost record — pay apps out to every GC.

Sub accounting means one cost ledger and a dozen ways each GC wants to see it — plus lien waivers, retention, and AR follow-up. AOS keeps billing on one record and outputs pay apps, waivers, and aging reports without retyping into every portal.

Your reality today

One ledger, many GC formats.

The math is right once. Then you reformat it for Procore, Sage, Foundation, and the GC who still wants a PDF — every month.

Pay apps re-typed per GC.

Same costs, different pay-app layout — your AP team learns every GC's quirks again each cycle.

Waivers hunted by state.

Statutory forms vary by state. You find the template, fill it, email it — per job, per period.

Retention in Excel.

Per-contract, per-GC liability with releases tracked in email — hard to trust at close.

AR follow-up is manual.

You know who's slow; the aging report across all GCs isn't automatic.

What AOS does for you

Billing and compliance from one cost record.

Maintain the schedule of values once. Generate waivers from the pay app. Track retention and AR by GC. Export to the GL you already run — AOS does not replace your payroll provider.
