Corpay, formerly known as FLEETCOR Technologies, provides business payment and expense management services, including fuel cards for commercial vehicle fleets and corporate payment processing tools that help businesses manage and control employee spending. Its fleet card business lets trucking and other commercial vehicle operators track and control fuel purchases across their vehicle fleets, while also giving Corpay data on fuel usage and spending patterns across its customer base. The company has expanded through acquisitions into broader corporate payments, including cross-border payments and accounts payable automation, moving beyond its original fuel card niche into a wider business payments platform. Corpay's revenue is tied to payment transaction volumes processed through its various platforms, along with fuel price levels that affect the dollar value, though not necessarily the underlying volume, of fuel purchases made through its fleet cards.
