The verdict in three sentences
An Amsterdam fleet manager running 40 vehicles must choose between a fleet SaaS (8 to 25 EUR/vehicle/month) and a custom build (35,000 to 90,000 EUR). SaaS goes live in days; custom pays off when your preventive-maintenance rules, incident handling and alerts must match your exact process. The numeric target: 15% lower maintenance costs and 20% less downtime through automatic alerts.
Fleet SaaS or custom: the 3-year math
SaaS cost grows with fleet size. For 40 vehicles, the subscription alone becomes a significant budget line that custom can rival.
| Criterion (2026 ballpark) | Fleet SaaS | Custom build |
|---|---|---|
| Entry cost | 8-25 EUR/veh./month | 35,000-90,000 EUR |
| For 40 vehicles/year | ~3,800-12,000 EUR | build + run |
| 3-year cost (40 veh.) | ~11,500-36,000 EUR | 35,000-90,000 EUR + run |
| Telematics (GPS, fuel) | Depends on plan | +6,000-15,000 EUR |
| Preventive maintenance alerts | Standard | +3,000-8,000 EUR custom |
| Business-rule customisation | Low | Full |
| Data ownership | Shared | Complete |
Below 20 vehicles, SaaS is the obvious choice. Around 40+ vehicles with specific needs (tippers, LCVs, high incident rates), custom is justified over 3-4 years.
Breaking down a custom budget
Here is a realistic split for a 40-vehicle fleet in Amsterdam in 2026.
| Module | 2026 range | Timeline |
|---|---|---|
| Core fleet + costs + documents | 35,000-55,000 EUR | 2-4 months |
| Telematics (GPS, fuel) | +6,000-15,000 EUR | 3-6 weeks |
| Preventive maintenance alerts | +3,000-8,000 EUR | 2-4 weeks |
| Incident and insurance management | +4,000-10,000 EUR | 3-5 weeks |
| Per-vehicle TCO dashboard | +3,000-7,000 EUR | 2-3 weeks |
| Annual maintenance | 15-20% of build | ongoing |
The preventive maintenance module is the most profitable: it triggers services at the right mileage and prevents costly breakdowns and downtime.

Mini case study
Nadia, fleet manager at a distribution firm in Amsterdam, runs 40 vans. Her annual maintenance costs reach 160,000 EUR and downtime costs about 90,000 EUR/year in replacement rentals and delays. She invests 62,000 EUR in a custom build (core + telematics + preventive alerts). Estimated result: 15% less maintenance (24,000 EUR/year saved) and 20% less downtime (18,000 EUR/year), or 42,000 EUR/year in gains. Payback in about 18 months, excluding annual maintenance.
FAQ
How much does fleet management SaaS cost in 2026? Expect 8 to 25 EUR per vehicle per month depending on features (telematics, maintenance, incidents). For 40 vehicles that is 3,800 to 12,000 EUR a year.
What budget for custom software? A full core starts at 35,000 EUR and climbs toward 90,000 EUR with telematics and incident management. Add 15-20% a year for maintenance.
From how many vehicles is custom justified? Generally beyond 30-40 vehicles, especially with specific business rules. Below that, SaaS stays cheaper.
What gain to expect from maintenance alerts? Well-run preventive maintenance cuts maintenance costs by 10 to 15% and downtime by 15 to 20% by avoiding unplanned breakdowns.
Is telematics essential? Not at first, but it sharpens fuel and driving tracking. Integration costs 6,000 to 15,000 EUR and pays off on large fleets through fuel savings.
