Technological advancements are no longer confined to a local scale, they have reached global dimensions with a far reaching scope. Information technology developers are currently driving this progress by rapidly creating precise, innovative solutions. Jobina Kitchen is a popular bakery in Padang, known for its delicious and visually appealing cakes and pastries. However, the business currently faces challenges regarding sales promotion, customer data management, and manual transaction recording. These issues complicate the processes of tracking transaction history and monitoring customer activity, resulting in time-consuming and inefficient operations. This study aims to design an e-commerce system using PHP and MySQL, incorporating Customer Relationship Management (CRM) principles to facilitate electronic customer transaction management. Data was gathered through direct observation at Jobina Kitchen, management interviews, and documentation of requirements. The study employs a case study method within a Software Engineering Research (SER) framework. The results demonstrate that the developed e-commerce system successfully integrates customer data management, transaction recording, and electronic storage of transaction history. Implementing this system can enhance service quality and expand Jobina Kitchen's sales reach, thereby increasing its competitiveness in the digital market.
