Custom Software Development

Car rental software

Car rental software shows which car is available on which dates, accepts bookings with an online deposit, creates the contract with a signature and photos at pickup and return, and reminds you about inspections, insurance and vignettes. Ready-made systems cost around 19 to 20 € per car per month; a custom system makes sense when bookings need to come through your website without commission and under your own rules: 3 000-29 300 € (based on 98 of our quotes as of 14 August 2026).

In brief: ready-made or custom system

Saitami's car rental system is on your website: online booking with payment, a contract signed on the phone, photos of the car at handover and return, and a fleet with expiry dates, with no per-vehicle fee. Yourenti costs 19 € per vehicle per month, every month.

A custom system makes sense when bookings mainly come through your website and need to be commission-free, when you have many cars and the per-car fee is high, or when you also have transfers, drivers and corporate clients with contracts.

Ready-made systems and their prices

Prices are from the manufacturer's website, reviewed on 17 October 2026, excluding VAT.

SystemPrice as listed on the websiteWhat to keep in mindSource
Yourenti20,00 € per car per month on a monthly contract, 19,50 € for 6 months, 19,00 € for a yearno setup fee; German systemyourenti.de/en/pricing

A car rental business with 30 cars pays 19 € times 30 times 36 months, or 20 520 € for three years. A custom system from us costs 3 000-29 300 €, with no per-car fee.

What the law requires

The system stores these details for every rental:

  • Rental agreement with the renter's details and driving licence, with a signature.
  • Valid third-party liability insurance, annual technical inspection and vignette for each car, with a reminder before expiry.
  • Receipt under Ordinance N-18 for cash or card payments at the office; invoice on request.
  • Personal data and document copies under GDPR: retention period and role-based access.

What we have built so far

For AGA Transfer and Maybach Transfers, we built websites with online booking, including a multilingual site for AGA. In the taxi dispatch system, cars and drivers appear on a real-time map, and payments can be made by card through myPOS or in cash. The fleet, routes and inspections are shown in the transport company demo.

What we have not done so far

We do not have a car rental company using a system we have launched, and we have not connected a system to car rental platforms or vehicle GPS trackers. So far, the location has come from the driver's app; we assess tracker integration based on the model.

What you gain

Commission-free bookings

From your website, with a card deposit.

Damage dispute with evidence

Dated photos at pickup and return.

No per-car fee

More cars do not increase the bill.
