Omnichannel retailing represents a transformation in how retailers design and manage their supply chains, as it requires seamless integration between physical stores, online platforms, mobile applications, and other customer touchpoints. Unlike traditional retail models where supply chains were linear and store-centric, omnichannel systems demand a customer-centric, flexible, and highly responsive supply chain strategy. This shift is fundamental because it changes the core objectives of supply chain management from efficiency and cost minimization alone to speed, visibility, and customer experience optimization. In a conventional retail system, inventory flows from suppliers to warehouses and then to stores, where customers make purchases. However, in an omnichannel environment, inventory must be accessible from multiple nodes simultaneously, allowing customers to buy online and pick up in-store, order from a store for home delivery, or return online purchases at physical outlets. This requires real-time inventory visibility across all channels, which fundamentally alters supply chain design. Retailers must invest in advanced information systems, integrated logistics networks, and data analytics to ensure synchronization between channels. One of the primary logistical challenges in integrating offline and online platforms is inventory management. Maintaining accurate, real-time inventory data across warehouses and retail stores is complex, especially when dealing with high product variety and fluctuating demand. Stockouts and overstock situations can arise if systems are not properly synchronized. Retailers must adopt technologies such as RFID, cloud-based inventory systems, and centralized databases to ensure transparency and accuracy. Another significant challenge is order fulfillment. In omnichannel retail, fulfillment is no longer limited to distribution centers; physical stores often act
