AOS Reviews & Product Details

Instead of a PM platform, an accounting system, a field app, and a pile of email, AOS keeps project management, pay applications, accounting, field paperwork, compliance, and closeout on one job record. It is built for mid-market general contractors and commercial subcontractors first, with views for owners, architects, residential builders, and permit expediters. Every GC account starts with drawings, RFIs, submittals, CPM scheduling, daily logs, punch lists, photos, change orders, pay apps generated from the schedule of values with retainage, a general ledger, and AP with approvals, 3-way match, payment runs, and lien-waiver gating. Subcontractors can respond through their own login or secure links. Each customer gets its own private database. Pricing is a flat monthly fee, never a percentage of construction volume.
