EPoS - Electronic Point of Sale System for Energy

EPoS Information

The Electronic Point of Sale (EPoS) system is DLA Energy’s front-line customer and business partner-facing system. EPoS is used to capture real-time military fleet management fuel retail transactions at unattended military service stations, mobile ground fuel transactions, and aviation fuel transactions for mobile airfield/flight line operations.

For the past 20 years, DLA Energy customers have been using the Automated Fuel Service Stations (AFSS) to obtain fuel at its 600+ capitalized fuel service stations. The EPoS system replaces AFSS as a modern, secure, and auditable fuel transaction processing system.
