Objectives and Success Criteria of The Online Car Rental System

The development in Information Technology and internet penetration has greatly improved various corporate processes and communication between services providers and their customers of which the car rental market is not left out.

Boost Business Processes:

The Internet connects us across the globe. This means if we start using Renting software like Car Rental System, we would able to increase our business.

Existing System of Online Car Rental System

Although many online portals have come into the picture for providing online car booking services. But most of the car renting company are using the traditional way to deal with the customer. Which are time and labor-consuming? An existing system can provide manual paperwork or an excel sheet to track the booking and registered vehicle details.

The user has to go to the office where the user can get the car on rent and book their car. Most of the time user does not get a sight of the car in which he is planning to travel. Which results in compromising the travel comfort. In the existing system, you cannot provide feedback of the user to the admin directly. The user gets fluctuation every time he/she travels.

Maintaining an excel sheet or paper book record of the reservation is very laborious work. Chances of error are more. No automation involves which means they are very slow to process.
