Abstract

Cahaya Mandiri Audio, an electronic service provider, is currently facing operational challenges due to its reliance on a manual record-keeping system, which has resulted in a data error rate of 15% and difficulties in maintaining customer loyalty. This study aims to design and build a web-based Customer Relationship Management (CRM) system capable of integrating customer data management, service history, and technician scheduling to optimize operations and improve customer retention. The development method used is the Prototype approach, utilizing the PHP programming language and the Laravel framework. The results of the study indicate that this system successfully unifies the roles of Admin and Technician within a single integrated platform, thereby minimizing human error and creating a more organized workflow compared to the previous manual system. The contribution and novelty of this system lie in the Scheduled Notification Module via WhatsApp, which facilitates the semi-automatic creation of message drafts through a redirect feature based on unit service history data to efficiently enhance customer loyalty.Keyword: CRM, Service, Laravel, Customer Loyalty, WhatsApp API.

Abstract

This research aims to design and build a website-based information system for gallon water sales and stock at the Cemani Refill Water Depot. The current problem is that the sales and stock recording process is still done manually, resulting in frequent recording errors, delays in reporting, and difficulties in monitoring inventory. This condition results in less effective and efficient operational processes. The system development method used in this research is a prototype method, which includes requirements gathering, prototype creation, prototype evaluation, system development, system testing, system evaluation, and system use. The system design was carried out using Unified Modeling Language (UML), while system testing utilized Black Box Testing.The result of this research is a web-based information system capable of managing sales data, gallon water stock data, customer data, and generating reports quickly and accurately. Based on the results of testing using the Black Box Testing method, all system features, such as login, customer data management, stock management, sales transactions, and report generation, functioned as expected without error. This system is expected to improve work efficiency, minimize recording errors, and facilitate business owners in monitoring business progress in real time.
