About
Billtrust is an accounts receivable automation and B2B payments company that provides a comprehensive order-to-cash platform for mid-market and enterprise businesses. Founded in 2001 and headquartered in Lawrenceville, New Jersey, Billtrust was acquired by FLEETCOR Technologies (now Corpay) to become part of one of the world's largest B2B payments businesses. Billtrust's platform covers the complete AR lifecycle from invoice delivery and customer payment portals through cash application, collections management, and credit decisioning, helping businesses accelerate cash flow and reduce the manual labor involved in managing large customer receivables portfolios.\n\nBilltrust's Business Payments Network (BPN) is a key differentiator, connecting AR teams with a network of buyer payment platforms and enabling electronic remittance matching that dramatically reduces the manual cash application work that burdens AR teams when customers pay by check or without detailed remittance information. The platform's AI-powered cash application engine automatically matches incoming payments to open invoices, handling complex scenarios like partial payments, short pays, and deductions, with automation rates that significantly reduce manual application work. Electronic invoice delivery, self-service customer portals, and automated collections workflows complete the AR automation suite.\n\nBilltrust competes with HighRadius, YayPay, Cforia, and the AR modules of large ERP systems, and has built particular strength in industries with high transaction volumes and complex payment scenarios including manufacturing, distribution, food and beverage, and wholesale. Its combination of AR automation software, B2B payment network capabilities, and now the scale of Corpay's payments infrastructure makes the combined entity a formidable competitor in the AR automation and B2B payments market.
