I have my own fleet, with several cars. But I want to organise them somehow so that I understand where and where my car is going. Where can I approach with such a question?
I can't tell you exactly how it works, but I know that there are special services where the car park is organised and you can find out a lot of detailed information there. How many cars did you have? You can find out about car rental software here https://rentprog.com . I don't think you will find a better service.
