A new AI-enabled in-vehicle payments platform is being rolled out to fuel retailers in major European markets under a new deal.

FleetWallet will now be available at over 5,300 fuel retailers across CarPay-Diem’s network of 12 European countries

Developed by Cubic, a global specialist in software-defined vehicle solutions, FleetWallet brings together smart fraud prevention, adaptive learning and real-time insights to revolutionise fleet management, without additional hardware. Compatible with all current fuel cards and telematics systems, it integrates into existing fleet operations.

Already available in the UK and other markets, it’s now being rolled out further under a new collaboration with CarPay-Diem; a mobile fuelling and digital marketing platform that enables pay-at-pump transactions by integrating into any app or connected vehicle.

Through this partnership, FleetWallet will now be available at more than 5,300 fuel retailers across CarPay-Diem’s network of 12 European countries, with further expansion across Europe scheduled for next year.

This network spans Austria, Belgium, Czech Republic, France, Germany, Hungary, Italy, Lithuania, Luxembourg, Netherlands, Poland and Spain – supporting commercial fleets such as haulage and HGV, along with delivery services, corporate fleets, car sharing and emergency vehicles.

CarPay-Diem partners with fuel brands such as Esso and Certas. The company has also confirmed continued fuel retailer growth across Europe, including the UK and Ireland.

Paul Foley, commercial director of FleetWallet, commented: “This partnership marks a major step forward for FleetWallet. Our work with GoCar Ireland proved our AI-enabled solution’s ability to prevent fuel misuse and simplify payments for shared mobility fleets. Partnering with CarPay-Diem allows us to scale across Europe – supporting fleets where cross-border refuelling and services like washing, parking and tolling demand seamless, secure in-vehicle payment automation. Together, we’re cutting fuel abuse and boosting efficiency across Europe’s fast-growing commercial vehicle market.”

Frédéric Stiernon, CEO of CarPay-Diem, added: “This collaboration enables us to deliver seamless, secure, and innovative in-vehicle payment experiences while supporting our continued growth across the region. Together with Cubic, we aim to ensure FleetWallet users have in-vehicle payment access to fuelling wherever they need it.”

FleetWallet delivers fleet management benefits, including real-time telematics and data analytics help fleets prevent theft and misuse. It’s said to unlock over 10% in fuel savings while minimising manual reconciliation.

The fully integrated, PSD2-compliant fleet payments enable hands-free management across Europe’s strictest financial and tax regulations. FleetWallet also delivers transparent, data-driven reporting and a single platform to manage vendors and services securely, simplifying operations across Europe’s diverse fuel and mobility networks.

Looking ahead to 2026, Cubic is advancing FleetWallet with AI-powered fraud detection, Smart Transaction Intelligence and predictive analytics. A new conversational assistant will let managers ‘talk to their data’, detect anomalies and act instantly – building intelligence that helps forecast costs, cut emissions and drive real-time efficiency.
