Usulan Sistem ERP untuk Transaksi Penjualan Produk pada PT. Sanjaya Teknik

Abstract. PT. Sanjaya Teknik is a manufacturing company that relies on conventional systems for managing sales transactions, inventory, and financial records, resulting in fragmented business processes, data duplication, and delays in information availability. This study proposes the implementation of an Enterprise Resource Planning (ERP) system to improve the integration and efficiency of sales transaction management at PT. Sanjaya Teknik. The research adopts the Christian Nebenführ approach to align organizational requirements, business processes, and the proposed ERP system. Data were collected through observation, interviews, and documentation studies. Business process analysis and system design were conducted using Business Process Model and Notation (BPMN), Use Case Diagrams, and Data Flow Diagrams. The results demonstrate that the proposed Odoo-based ERP system, integrating Sales, Purchase, Inventory, Accounting, Invoicing, Website, and Customer Relationship Management (CRM) modules, enables centralized and real-time sales process integration. The proposed system is expected to enhance data accuracy, operational efficiency, and managerial decision-making. Abstrak. PT.
