The juice bar management system is fully and accurately implemented to be able to use readily. This incorporates the functionality of the function and its activities and the validations were needed. In this shop they are manually updated their journals and they issue hand written bills to customers. This method is very difficult to them because they are facing so many difficulties during the shop get crowded. There was no computerized database to this juice bar and because of that they got couple of issues with supplier details, stores and transactions. These are some of main issues with their manual system and the reasons to ask for an automated system. Based on the requirements of the client, all the languages and the order of activities are used to make it easy for the client. The system gives access to clients to keep stocks, manage employee details, inventory details, customer details, supplier details, sales details, wastage details, profit details and also order details. Finally this system is developed to satisfy the client’s needs and the needed software. The main goal as the developing team was to make the system simple and user friendly with filing all the requirements the client asked for.
