This research aims to design and implement an integrated Customer Relationship Management (CRM) system to optimize the service process at PT Denpasar Agung Indah Motor. The system is designed using the DevOps development method, which allows development to be done iteratively and efficiently. The CRM system involves five types of users, namely customers, sales, CCO, service advisors, and leaders, with the main features including customer data management, service reservations, product marketing, and report generation. System testing using the blackbox testing method shows that all features have functioned according to the specified functional requirements. The results show that this CRM system not only improves the company's operational efficiency, but also strengthens relationships with customers, which ultimately increases the company's competitiveness.
