Proprietary replacement timing models save money by optimizing vehicle lifecycle decisions
Massive maintenance network with 50,000+ service providers and pre-negotiated labor rates
Fuel card programs catch fraud and typically save 3-8% on annual fuel spend
Over 55 years of fleet data informs the analytical models behind every recommendation
Now backed by the combined Wheels organization with 800,000+ vehicles under management

No longer exists as a standalone brand—you sign with Wheels now
Migration from legacy Donlen systems to Wheels platform caused disruption for some clients in 2022
Enterprise-only pricing makes it inaccessible for fleets under 100 vehicles
No self-service option—everything requires a dedicated account manager and sales process

Accepted at 95% of US fuel stations—drivers almost never have to search for coverage
Savings of 15-25¢ per gallon add up fast, especially for fleets burning 10,000+ gallons monthly
IFTA tax reporting automation eliminates days of manual quarterly prep work
Layered fraud controls with real-time alerts catch suspicious transactions before they spiral
No monthly software fee—WEX earns from transaction margins, keeping costs transparent

Not a fleet management platform—zero GPS tracking, route planning, or maintenance scheduling
Customer support quality varies significantly between large accounts and smaller fleets
Fuel savings depend heavily on negotiated rates—smaller fleets get less favorable terms
US-centric network means limited value for fleets operating in Canada or internationally
