ScalaCode partnered with a client to replace an outdated DOS-based handheld stock terminal with a state-of-the-art Android application for inventory and order management. The goal was to enhance functionality, improve data handling, and provide an intuitive user experience while ensuring compatibility with SUNMI L2S Pro terminals.
Develop an Android application to replace the legacy Unitech HT630 terminal.
Integrate core inventory functions, including stock management, order handling, deliveries, price checks, and transfers.
Ensure seamless integration with the client's existing EPOS system.
Provide a robust, user-friendly interface tailored for the rugged SUNMI L2S Pro device.
Include offline functionality with local data storage and synchronization when connected.
Built the Android application using Kotlin and Jetpack Compose for a responsive and intuitive UI.
Designed local storage solutions with SQLite and Android File API, enabling seamless offline use and synchronization with the EPOS system upon connection.
Ensured the architecture was future-ready to accommodate enhancements and scalability.
Established efficient data import/export processes for seamless synchronization with the EPOS system.
Conducted wire framing and mock-ups to optimize workflows and minimize user errors.
