Fuel management software combines real-time measurement of each vehicle's fuel consumption, fuel card transaction integration, automatic anomaly detection and cost reporting in an exportable dashboard. It lets a fleet manager know the actual fuel cost of each vehicle, instead of working from fleet averages based on consolidated invoices. Fleeti covers the whole chain, from the sensor on the vehicle to exports for the finance department and ESG reporting.

Fleeti collects engine data via the vehicle's CAN bus or OBD port on recent fleets, giving access to instant fuel use, engine speed, road speed and idling time. On construction machinery, older trucks and vehicles without an FMS interface, a capacitive probe is installed directly in the tank: it measures the fuel level independently of the original control unit. Both methods can coexist on the same fleet within a single platform.

The CAN bus measures engine consumption as calculated by the vehicle's control unit: it is very accurate for instant readings, but only works on recent vehicles with the FMS protocol. A capacitive probe measures the fuel level in the tank directly: it is less accurate for instant consumption but more reliable for detecting a sudden drop (siphoning), and it works on every vehicle, whatever its age or powertrain. Most fleet management software on the market (Geotab, Webfleet, Quartix) relies on the CAN bus alone, which leaves construction machinery and older fleets uncovered. Fleeti systematically combines both approaches on one platform to cover mixed fleets, particularly off-road diesel construction machinery and older trucks.

Three combined mechanisms detect fuel theft. First, an abnormal drop in tank level between two trips, measured by the capacitive probe: siphoning is flagged immediately. Second, a refuel outside an authorised area or outside working hours, cross-checked with the vehicle's GPS position: fuel card fraud becomes traceable. Third, a transaction volume exceeding the tank's capacity at the time of refuelling: the excess is flagged as an anomaly. Like Optimum or SuiviDeFlotte, Fleeti detects these anomalies in real time. What sets Fleeti apart is that it systematically archives time-stamped evidence (date, GPS position, level before and after, related transaction) to build an enforceable file for the insurer or the police, with no manual work by the fleet manager.

Fleeti automatically cross-checks each fuel card transaction with the GPS position of the vehicle the card is assigned to. A transaction made while the vehicle is elsewhere (card used by someone else, fuel for a personal vehicle) triggers an alert. Likewise, a volume greater than the tank's remaining capacity at the time of refuelling, or a refuel at a station far from the vehicle's usual route, is flagged as suspicious. You have a complete history for every driver and every card.

Typical savings after deploying fuel management software range from 15 to 25% of the annual fuel bill. Several gains add up: identifying high-consumption vehicles, targeted training for drivers with costly habits, detecting phantom refuels and fuel card fraud, and cutting excessive idling. On a fleet of 100 vehicles using 8 litres per 100 kilometres and driving 25,000 kilometres a year, a 15% saving means tens of thousands of euros of fuel not burned each year. Fuel management software usually pays for itself in under twelve months.

Yes. Construction machinery running on off-road diesel is one of the most common use cases on the Fleeti platform. Measurement relies on a capacitive probe installed directly in the tank, independently of the machine's control unit, which measures fuel level and detects theft even on older excavators, loaders, dumpers and compactors. Consumption is expressed per engine hour rather than per 100 kilometres, which is more relevant for machinery. Engine hours are tracked too, to help with replacement and preventive maintenance decisions.

Yes. Fleeti integrates the main fuel cards used by business fleets. Transaction statements are retrieved automatically, with no action needed from your provider. You keep your current contract and simply add the management and anomaly detection layer. If your provider is not yet integrated, the Fleeti team can build the connector as part of the rollout.

Fuel management on a mixed fleet relies on three levels of control. First, measurement: CAN bus for recent vehicles, capacitive probes for machinery and older trucks, self-reporting and fuel cards for office-based fleets without on-board telematics. Second, monitoring: litres per 100 kilometres, litres per engine hour and cost per kilometre, continuously compared with the fleet median. Third, alerts: any overconsumption, excessive idling or abnormal refuel is flagged in real time. Fleeti centralises fuel management for the whole fleet on one platform, whatever the powertrain (petrol, diesel, off-road diesel, hybrid, electric).
