Transforming Construction Payments
Construction has shaped human progress since ancient times. But, while building methods have evolved, the industry's payment processes remain in the past. According to McKinsey, construction ranks among the least digitized industries—particularly when it comes to billing and payments.
The Problem
For subcontractors, getting paid is a complex, drawn-out process. Despite fronting labor and materials costs, they're last in line for payment. The typical wait? 90 days after completing work. Slow payments cost the construction industry $280B in 2024 and have been a primary reason for 73% of subs obtaining financing to front the cost of projects (per Rabbet’s 2024 Construction Payments Report).
