The verdict in three sentences
Custom fleet management software costs EUR 30,000-70,000 in 2026, ships in 10 to 18 weeks and is maintained at 8-12% of cost per year. Its value lies in anticipated maintenance alerts, real-time telematics and per-vehicle cost tracking. ROI hinges on reduced downtime: every day a truck sits idle is costly, and anticipating breakdowns melts it away.
Cost by module
Budget is built from the activated blocks. A maintenance + costs + telematics core covers the essentials, then fuel cards and a portal are added.
| Module | 2026 range (EUR) | Indicative timeline |
|---|---|---|
| Maintenance tracking + alerts | 8,000 to 18,000 | 3 to 6 weeks |
| Per-vehicle cost tracking | 6,000 to 14,000 | 2 to 5 weeks |
| Telematics / geolocation | 8,000 to 20,000 | 3 to 6 weeks |
| Fuel card integration | 4,000 to 10,000 | 2 to 4 weeks |
| Driver portal / booking | 4,000 to 12,000 | 2 to 4 weeks |
| Typical project total | 30,000 to 70,000 | 10 to 18 weeks |
ROI: reduced downtime
The main gain is avoiding breakdowns and idle days. 2026 order-of-magnitude estimate.
| Item | Without software | With software | Est. annual gain |
|---|---|---|---|
| Downtime days | baseline | -35% | ~EUR 14,000 (15-vehicle fleet) |
| Curative maintenance costs | baseline | -20% | ~EUR 9,000 |
| Fuel tracking / fraud | manual | automated | ~EUR 5,000 |
| Admin time | 2.5 h/day | 0.5 h/day | ~EUR 9,100 |
| Total | ~EUR 37,100/yr |
For a 15-vehicle fleet, an EUR 55,000 investment pays back in about 18 months.

Mini case study
Julien, fleet manager at a construction firm in Dublin, runs 18 vehicles and machines. He invests EUR 58,000 in custom software (maintenance, costs, telematics, fuel cards), delivered in 15 weeks, with EUR 6,000/year maintenance (10%). Maintenance alerts anticipate breakdowns: -35% downtime days, i.e. about EUR 16,500 saved, plus EUR 6,500 on fuel and EUR 9,000 in admin time. Total gain around EUR 32,000/year: investment paid back in 22 months, then over EUR 26,000 net per year.
