A Change Order Happened on Site Today. It Will Never Make It to an Invoice.

Rigby captures every piece of billable construction work, from change orders to progress billing:

  • Up to 30% of revenue lost to change orders that vanish on site
  • Subcontractor invoices arriving in a dozen formats
  • Progress billing tied to milestones that shift weekly

Automated invoice generation tied to completed work, approved changes, and verified deliveries. Your billing cycle drops from weeks to days.

Payra ($15M raise, Feb 2026) automates accounts receivable for construction suppliers. They handle payment collection. Rigby automates the procure-to-pay lifecycle upstream: capturing change orders, reconciling subcontractor invoices, matching purchase orders, and generating the invoices that AR tools then collect on.
