Fuel retail isn't "just retail".

When IFSF, SMA and HSM all mean things then you know you understand fuel-retail technology. We understand the vital importance of 24/7 operations and ensuring that truck driver always gets their fuel at 2am to keep moving.

WHAT FLUX DOES

Access the forecourt, through your customer's phone.

01
Pay in car, done properly.

Flux handles the full pay-in-car flow: pump pre-authorisation, payment processing, and fund locking. It integrates directly with your Site Management Application (SMA) over IFSF or vendor-specific protocols — processing every transaction in sub-second timeframes.

02
A personalised storefront for every customer.

Flux is the window between your backend and your customer's phone. When paired with Radium's Nebula loyalty engine, every targeted promotion, reward or loyalty mechanic can become a live engagement in the app. This means the right offer, to the right person, at the right time.

03
Bring value to unmanned sites.

No staff doesn't mean no service. Flux turns your app into the customer touchpoint — loyalty, payment, promotions and site information, all accessible without anyone behind a counter.

04
Real-time site and pump information.

Location, pump availability, fuel grades — your app surfaces live site data so customers know what's available before they arrive.

THE BENEFITS

What it means to run Flux in production.

Built to handle the load.

One site or one thousand, Flux handles the load. Production-grade for the transaction volumes of real fuel retail — not a prototype that passes tests and fails on a Friday night.

Refresh the look, without the risk.

Flux doesn't dictate what your app looks like. Bring your own design, your own front-end team, your own brand. When the UX needs a refresh — and it will — you ship it. The backend doesn't move.

One app. Not two.

Drivers, fleets (B2B) and consumer (B2C) transact ont he same platform with the right rules, pricing and loyalty logic applied at the right moment. No double-dip between card discounts and points. No two teams shipping two apps.
