ABSTRACT Umbwa Kali car wash is facing a problem of poor management and the sharing of information with its customers. All activities and services advancement reports in Umbwa Kali Car Wash are done manually; and this causes a waste of time and outperformance of the car wash. The purpose of this work is to design and implement a web based application which will help this car wash to manage all problems relating to the communication between customers, employees and car wash staff. This application offers the ability of communicating with customers and car wash management quickly. It also offers the owner of car wash the ability to view all activity processes done by managers on daily basis through bill reports. For the development of this project two methodologies will be used: the research methodology and the software engineering methodology. Research methodology consists of interviewing and reviewing and the literature necessary to carry out this study. The population of this study is 60 including 40 employees of the carwash and 20 customers. Employees are many compared to customers because most of time customers are used to leave their car to the car wash to pick them back when they have been cleaned, this was the main challenge to the researcher because to find customers present to the car wash was not easy.
