The verdict in three sentences
For a rental company with 100 to 600 vehicles, custom fleet and rental management software costs between EUR 30,000 and 80,000 excluding VAT in 2026 and ships in 3 to 5 months. The main financial lever is utilisation, which rises by around 7 points once availability is visible in real time and online booking replaces the phone. Below 60 vehicles, a SaaS rental tool at EUR 15 to 25 per vehicle per month remains the rational choice.
What paper really costs
The manager of a rental branch in Hamburg, Bremen or Kiel handles van check-outs and returns every day, disputed damage inspections and services planned on a whiteboard. Losses are quiet but they add up.
| Loss item | 2026 order of magnitude (250-vehicle fleet) |
|---|---|
| Average utilisation without software | 58 to 65% |
| Damage not recharged for lack of photo proof | EUR 15,000 to 40,000 per year |
| Time per paper inspection | 15 to 20 minutes |
| Downtime days from unplanned servicing | 4 to 8 days per vehicle per year |
| Fines and tolls reassigned by hand | 6 to 10 hours per week |
| Bookings lost outside opening hours | 8 to 15% of demand |
On a 250-vehicle fleet rented at EUR 55 per day on average, each utilisation point is worth about EUR 50,000 in annual revenue.
Modules and budget for custom software
| Module | Scope | Indicative cost (excl. VAT) |
|---|---|---|
| Online booking | Real-time availability, dynamic pricing, payment and card pre-authorisation deposit | EUR 6,000 to 14,000 |
| Contracts and invoicing | E-signed contracts, mileage, excess, accounting export | EUR 5,000 to 12,000 |
| Photo inspection | Tablet app, time-stamped geotagged photos, customer signature | EUR 4,000 to 10,000 |
| Maintenance | Service plans by mileage, TÜV/HU deadlines, alerts | EUR 4,000 to 9,000 |
| Telematics | GPS box integration, automatic mileage, fuel level | EUR 5,000 to 15,000 |
| Fines and tolls | Automatic driver nomination for authorities | EUR 2,000 to 6,000 |
| Dashboard | Utilisation by category and branch, profitability per vehicle | EUR 4,000 to 14,000 |
A single-branch version with booking, contracts and inspection starts around EUR 30,000 to 40,000. A network of 4 to 6 branches with telematics, dynamic pricing and accounting ERP integration reaches EUR 65,000 to 80,000. Maintenance and hosting represent 12 to 18% of the initial budget per year, excluding telematics subscriptions (EUR 8 to 15 per box per month).
Custom or off-the-shelf SaaS

Mini case study
Jonas, managing director of a van rental company in Hamburg, runs 220 vehicles at EUR 52 per day on average, with 61% utilisation. He invests EUR 58,000 in software with online booking, photo inspection and telematics. After six months utilisation reaches 67%: 220 × 365 × 6% × EUR 52 = EUR 250,000 in extra revenue per year. Damage recharged thanks to photos adds EUR 22,000. Even at a 25% net margin on the additional revenue, the project pays back in under 10 months.
FAQ
What budget for a small 100-vehicle company? Allow EUR 30,000 to 40,000 for booking, contracts, inspection and maintenance. Telematics can come in a second phase for EUR 5,000 to 15,000.
Is telematics GDPR compliant? Yes, if customers are informed, geolocation is limited to contract management and position data is kept for a short, documented period, typically 2 months, with a works council agreement for staff vehicles.
Can we migrate our contract history? Yes, migrating 3 to 5 years of contracts and vehicle records from Excel or legacy software usually takes 2 to 3 weeks.
How much time does an inspection save? With a tablet, an inspection goes from 15 to 20 minutes to 5 to 7 minutes, photos and signature included.
Does the software handle deposits? Yes, through card pre-authorisation with a European payment provider, with partial capture when damage is documented.
