Micro, Small, and Medium Enterprises (MSMEs) of Kopi Muria Zayna still face challenges in managing production and sales activities that are conducted manually and are not yet integrated. This condition results in weak control over raw material inventory, suboptimal production planning, and inaccurate sales recording and reporting that require considerable time. This study aims to analyze the role of an Enterprise Resource Planning (ERP) system in supporting production and sales management at Kopi Muria Zayna MSME. The research employs a qualitative approach with a descriptive case study method through several stages, including analysis of the existing system (As-Is), identification of system requirements, and design of the proposed ERP-based system (To-Be). Data were collected through observation, interviews, and documentation, while system analysis was conducted using the PIECES framework. The results indicate that an ERP system conceptually has the potential to improve production process efficiency, enhance integrated management of raw material and finished goods inventory, and support more accurate and structured sales recording and reporting. Furthermore, ERP can assist MSME owners in making more precise and timely data-driven decisions. Therefore, the ERP system plays a strategic role in supporting operational effectiveness and the long-term business sustainability of Kopi Muria Zayna MSME.
