The verdict in three sentences
On an unmanaged fleet, fuel leakage reaches 5 to 15 % through siphoning, ghost trips and engine waste, while maintenance costs stay a black box. A fleet management app logs refuels, trips and servicing per vehicle, computes cost per km and schedules preventive maintenance. The result: fraud becomes visible, breakdowns drop, and every vehicle becomes a measured cost centre.
Where money leaks in a fleet
The carrier who does not measure pays twice: for stolen fuel and for the breakdown not anticipated. Here is a 2026 order of magnitude for a truck running in Lagos, Dakar or Abidjan.
| Item | Without app | With app | Gap |
|---|---|---|---|
| Fuel / month | 900,000 FCFA | 780,000 FCFA | -13 % |
| Unplanned breakdowns / yr | 8 | 3 | -62 % |
| Downtime / yr | 40 days | 15 days | -62 % |
| Parts cost / yr | 1,200,000 FCFA | 850,000 FCFA | -29 % |
| Cost per km | 520 FCFA | 430 FCFA | -17 % |
| Engine lifespan | baseline | +20 to 30 % | + |
Simply reconciling litres bought, kilometres driven and theoretical consumption surfaces the gaps nobody was watching.
The app's levers
| Feature | What it controls | 2026 gain |
|---|---|---|
| Refuel log | Litres vs real km | -5 to 15 % leakage |
| Cost per km / vehicle | Profit per truck | Renewal decisions |
| Preventive maintenance | Mileage / date alerts | -50 to 60 % breakdowns |
| Driver behaviour | Speed, braking, idling | -8 to 12 % consumption |
| GPS integration | Real trips, detours | End of ghost runs |
| Parts tracking | Stock and history | -20 to 30 % spend |
Tracking driver behaviour (harsh acceleration, prolonged idling) is often the fastest gain: it costs nothing in hardware and quickly turns into litres saved.

Mini case study
Ibrahim runs 6 trucks in Lagos. His fuel bill ran at 5,400,000 FCFA/month for the whole fleet, with unexplained gaps. After deploying the app (refuel log + GPS), he detects 11 % leakage and brings it to 3 %, saving 432,000 FCFA/month. Add preventive maintenance cutting downtime by 25 days/vehicle/year, and he recovers the equivalent of one and a half trucks of availability. The app, at 2,500,000 FCFA, pays back in under six months on fuel alone.
FAQ
Do you need GPS units on every vehicle? Recommended but not mandatory at first: you can start with manual entry of refuels and trips, then add GPS units at 25,000 to 50,000 FCFA each to firm up the data.
How much does a fleet management app cost? A business app with fuel log, cost per km, maintenance and driver tracking runs 2,000,000 to 4,000,000 FCFA in 2026, depending on the number of vehicles and integrations.
How does the app detect fuel theft? It reconciles billed litres, GPS kilometres and the vehicle's theoretical consumption: any lasting gap flags siphoning or fictitious refuels to investigate.
Is preventive maintenance worth the cost? Yes: anticipating oil changes and wear parts halves breakdowns and cuts downtime by 60 %, worth far more than the price of scheduled servicing.
Can you track multiple drivers and allocate costs? Yes, each trip is tied to a driver and a vehicle, letting you compare consumption, reward the best and target training.
