Nexus AP automates accounts payable for construction companies by streamlining subcontractor invoice processing, lien waiver compliance, and job cost allocation. The average general contractor processes over 1,000 invoices per active project annually, with 23% requiring manual rework due to incorrect job coding. Nexus AP eliminates these errors with AI-powered cost code assignment and automated lien waiver tracking that prevents payment release until compliance is verified.
Key Industry Data
- 68% of construction firms report lien waiver tracking as their top AP compliance challenge: Construction Financial Management Association (CFMA) (2025)
- Average cost per invoice in construction is $18.42, compared to $12.90 cross-industry average: Ardent Partners - AP Metrics That Matter (2025)
- Incorrect job coding accounts for $4.2B in annual rework costs across the U.S. construction industry: Associated General Contractors of America (AGC) (2024)
“We used to have two full-time employees just chasing lien waivers and reconciling job codes. After implementing AP automation, our job coding accuracy went from 91% to over 99%, and we have not had a single lien claim in eighteen months.”
