WEX
WEX operates one of the largest fleet and fuel payment networks. Paygasus processes fleet and fuel transactions on the WEX network, bringing closed-loop fleet acceptance to unattended and in-person sites.
WEX is the fleet and fuel layer — closed-loop card acceptance for fleets, fuel, and EV charging across Paygasus sites.
The fleet and fuel payments network
WEX is a global leader in fleet, fuel, and corporate payment solutions, operating closed-loop card programs used by millions of vehicles and thousands of fleets. Its network handles fuel, maintenance, and fleet-specific payment controls that ordinary card rails don’t.
Fleet and fuel buyers carry cards that need network-specific acceptance and controls. Processing on WEX lets Paygasus sites — including unattended fuel and EV charging — accept fleet cards with the right data and limits in place.
