For this project, it was necessary to implement an omnichannel experience that integrates customer management, products, and sales flows into a single platform. We chose MedusaJS as the foundation for this architecture, and alongside the core platform, several complementary applications were developed: Internal mobile application for managing incoming inventory, tracking stock, and placing quick orders directly from the store aisles. POS application for checkout, allowing staff to scan products and automatically issue fiscal receipts, or fulfill orders submitted directly from the aisles. All of these applications are interconnected, providing unified access to customer data, including purchase history, delivery addresses, and other key sales insights. To complete the ecosystem, the online store was also developed, specifically designed to be intuitive and user-friendly. Powered by the same centralized platform, inventory levels displayed on the website are updated in real time, eliminating product availability issues and improving the overall shopping experience.
