<![CDATA[The development of information technology has encouraged industries to transition to digital systems to improve operational efficiency and service quality. CV Tjahaya Logam, a nail manufacturing company, still relies on a manual ordering system, which may lead to recording errors and delays in order confirmation. To address these issues, the NailFlow application interface was designed using the Design Thinking method, which consists of five stages: Empathize, Define, Ideate, Prototype, and Test. This study aims to develop a user interface (UI) and user experience (UX) design that is intuitive, efficient, and responsive to the needs of customers and company administrators. The resulting prototype incorporates key features, including digital ordering, real-time order tracking, and inventory management. Testing using the Black Box Testing method indicates that all interface elements function as expected. The proposed interface design is expected to improve the efficiency of the ordering process, minimize errors]]>
