Implementation of a Web-Based Management System for Geraifone Store Using the Waterfall Methodology

Abstract

This study presents the development of a sales management website for Geraifone Store, focused on managing mobile phone and accessory transactions. The development process follows the Waterfall methodology, consisting of requirement analysis, system design, implementation, testing, and maintenance stages. The website provides an admin dashboard with several key features, including product management, customer management, sales transaction handling, and sales reporting. The product management feature supports full CRUD operations, allowing the admin to manage product details such as name, brand, specifications, purchase price, selling price, and stock quantity. Customer management enables the storage and maintenance of customer data. The transaction module records sales activities, including product selection, quantity, and payment status. The reporting feature displays comprehensive sales reports, which can be filtered by date range to help monitor daily, weekly, or monthly sales performance. The result of this development indicates that the system effectively supports structured, centralized, and efficient sales management for the store.
