  Buildxact is a Melbourne, Australia-headquartered construction estimating and project management SaaS for residential
  builders, remodelers, trade contractors, and building-material suppliers. Founded in 2011, the company operates
  regional offices in Austin, Texas (North America), and serves customers across Australia, New Zealand, the United
  Kingdom, the United States, and Canada. The platform spans the full residential job lifecycle — lead capture, digital
  takeoffs, AI-assisted estimating ("Blu"), customer quoting and e-signatures, supplier/dealer price-list integration,
  purchase orders, scheduling (Gantt), timesheets, variations/change orders, invoicing, and two-way accounting sync with
  Xero and QuickBooks Online. Buildxact exposes a public REST API and webhook surface at developer.buildxact.com,
  available to Merchant and Manufacturer partners as well as customer subscribers, using a Microsoft Azure API
  Management gateway (Ocp-Apim-Subscription-Key + bearer token). Endpoints support OData filtering and sorting, with a
  separate UAT/staging environment. In 2024, Autodesk announced an agreement to acquire Buildxact, positioning the
  product as a residential construction front-end alongside Autodesk's broader AEC portfolio.

    Buildxact's webhook surface lets partner and customer integrations receive real-time notifications
    when events occur inside the construction-management platform — including Estimate Accepted, Lead
    Created, and Lead Updated, plus additional event types reserved for Merchant and Manufacturer plan
    tiers. Webhooks are registered from the "My Business > API" panel of the Buildxact web app: provide
    a destination URL, choose events, store the signing secret used to verify payload authenticity, and
    inspect deliveries via the built-in Event Log. Payloads are JSON over HTTPS.
