Fleet management software is a program with which a company monitors and manages its vehicles and drivers from a single dashboard. Location, maintenance schedule, fuel consumption, tyre changes, inspection and insurance expiry dates and the validity of driver documents are gathered in the same record. The aim is to increase vehicle uptime, reduce the risk of breakdowns and fines, and make the cost per kilometre visible.
What data does fleet management software bring together?
The focus of fleet software is not the cargo but the vehicle and the driver. A record is opened for each tractor unit, trailer and light commercial vehicle, and all events relating to that vehicle are entered on it. Module names vary by vendor, but the content is similar:
| Module | What does it record? | Example alert |
|---|---|---|
| Location and usage | Location, mileage, engine hours and idling from the telematics device | Vehicle has been idling for 3 hours |
| Maintenance | Scheduled maintenance, fault records, service invoices | 2,000 km left until oil service |
| Fuel | Fuel card transactions, tank level, litres/100 km | Consumption 18% above fleet average |
| Tyres | Tyre serial number, axle fitted, tread depth | Front axle tyre at replacement limit |
| Documents and deadlines | Roadworthiness inspection, compulsory traffic insurance, tachograph calibration, ADR certificate of approval | 15 days until inspection expires |
| Driver | Driving licence, SRC, psychotechnical assessment, driving score, tachograph data | SRC certificate expiring |
Why is separate software needed?
In a fleet of forty tractor units, document dates alone mean hundreds of deadlines a year. Missing just one means the vehicle is stopped at the border or at a roadside check. The tachograph side adds to the workload: EU legislation expects data from the vehicle unit to be downloaded at least every 90 days and driver card data at least every 28 days. According to the European Commission, since 1 July 2026 tachographs have also been mandatory for 2.5–3.5 tonne light commercial vehicles carrying out international transport for hire or reward. Keeping this calendar in spreadsheets is possible, but the margin for error is high.
On the cost side, the software answers the question "which vehicle is costing us the most?". When fuel, maintenance and tyre costs are divided by kilometres, ageing vehicles and inefficient driving habits become visible in numbers.
How does it work?
- Vehicles, trailers and drivers are defined in the system; documents are uploaded with their dates.
- Location, mileage and fuel data start flowing from a device fitted to the vehicle or from the manufacturer interface (FMS). The data flow relies on the telematics device and the GPS vehicle tracking system.
- Rules are set for maintenance intervals, document expiries and consumption thresholds; the software sends an e-mail or notification when a rule is breached.
- Fuel card, service and accounting records are imported.
- Monthly reports are compared by vehicle, driver and route.
How does it differ from a TMS, and how are the two connected?
| Criterion | Fleet management software | TMS |
|---|---|---|
| Focus | Vehicle, driver, maintenance, cost | Order, trip, cargo, customer |
| Key question | Is the vehicle on the road in good condition and legally? | Was the cargo assigned to the right vehicle and delivered on time? |
| Typical user | Fleet and maintenance manager | Operations and planning team |
When planning trips, the TMS (transport management system) learns from the fleet software which vehicles are available: a vehicle in maintenance or with an expired inspection does not appear in planning. In the other direction, trip mileage and revenue data flow back to the fleet software, so profitability per vehicle can be calculated. On the cargo owner's side, the same location data takes the form of daily vehicle tracking and reporting.
Who is responsible?
The software is usually managed by the fleet manager; the maintenance team updates work orders and human resources updates driver documents. Because location and driving behaviour data may count as personal data, the company, as data controller, must define the privacy notice, retention period and access rights within the framework of the rules on vehicle tracking data under KVKK (Turkish Personal Data Protection Law).
Common mistakes
- Uploading documents on day one but not entering renewals in the system; after a while the alerts become meaningless.
- Not defining subcontractors' vehicles at all; half of the fleet remains invisible.
- Not matching fuel card data with location; a purchase at a station where the vehicle was not present goes unnoticed.
- Setting up many alert rules without prioritising them; the team misses the alert that really matters.
