Where does a rent a car company lose money?
The same car handed to two customers, being unable to prove whether damage found at return already existed at check-out, bridge and motorway crossings during the rental period billed to the company months later, a car with expired insurance or inspection going out on rent: these are all losses caused by scattered tracking.
Car rental software keeps every day of every car in a single calendar, records photos at check-out and return, matches crossings and fines to the rental contract, and gives advance notice of upcoming maintenance, insurance and inspection dates.
Online booking and pricing
- Pickup and return office, airport or hotel delivery; one-way return fee
- Stock and availability per vehicle group; blocking of overlapping bookings for the same dates
- Tiered pricing by number of days, seasonal and weekend rates, long-term rentals
- Extras such as additional driver, baby seat, navigation, mini damage cover and full comprehensive insurance
- Age and years-of-licence requirements, deposit amount and card pre-authorization
- 3D Secure payment, deposit or pay at pickup; virtual POS integration
The website works in multiple languages and currencies; in tourist regions, foreign customers see prices in EUR or GBP, and booking confirmations go out by email and WhatsApp.
Check-out, return and damage records
At check-out, staff use the mobile app to record the car's mileage, fuel level and photos from all four sides, existing damage is marked on the vehicle diagram, the customer signs on screen and the contract is sent to the customer as a PDF. The same steps are repeated at return; new damage, missing fuel and excess mileage charges are calculated automatically by the system.
Deposit refunds or deductions are based on these records; in case of a dispute, date- and time-stamped photos are ready as evidence.
Fleet, HGS, fines and legal records
Each car's plate, chassis details, inspection, mandatory traffic insurance, comprehensive insurance and maintenance dates are stored; upcoming dates appear as alerts in the panel and by email. HGS crossings and traffic fines are matched by date and time to the renter driving the car at that moment, and the amount to be charged to the renter is added to the contract.
Rented vehicle and renter details must be reported to KABİS (Kiralık Araç Bildirim Sistemi); the system keeps the renter's ID, driving licence and rental details ready for reporting. Per-vehicle profitability, utilization rate and per-office revenue reports come from the same panel.
Together with transfers and used car sales
For companies at airports that both rent cars and run transfers, transfer booking software can be added to the same system as a module. For companies selling cars while renewing their fleet, it connects with vehicle valuation software and a car buying and selling platform.

Frequently asked questions
What does car rental software manage?
It manages online booking, the vehicle availability calendar, prices and extras, payments and deposits, check-out and return forms, rental contracts, HGS and fine tracking, fleet maintenance and insurance alerts, and reports.
How do you prevent the same car being rented to two people?
Bookings are kept in the calendar per vehicle and vehicle group; the system rejects overlapping date ranges, and when a group's stock runs out, that group is no longer sold on the website.
How are damage and deposit disputes resolved?
Date- and time-stamped photos, a damage diagram and the customer's signature are recorded at check-out and return; deposit deductions are based on these records.
Can it handle KABİS reporting?
The system keeps the renter's ID, driving licence and rental details ready for KABİS reporting; the reporting method and integration scope are defined according to the access your company uses.
Can it connect to our existing website?
Yes. The booking engine can be embedded in your existing website or connected via API; if you want a new website, it is built from scratch and SEO-friendly.
How is the price determined?
An itemized quote is prepared based on the number of offices and vehicles, the mobile check-out app, and payment and integration needs.
