Omnichannel retailing has transformed the traditional boundaries of supply chain management by integrating multiple sales and distribution channels into a unified customer experience. Unlike conventional retail models where physical stores and online platforms operate independently, omnichannel retail requires seamless coordination across all touchpoints, including brick-and-mortar stores, e-commerce websites, mobile applications, and social commerce platforms. This shift necessitates a fundamental rethinking of supply chain strategy, as the focus moves from efficiency-driven, linear flows to customer-centric, agile, and responsive networks. In traditional retail supply chains, inventory is often allocated to specific channels, and replenishment decisions are made based on predictable demand patterns. However, omnichannel retailing disrupts this model by introducing dynamic demand fulfillment options such as buy-online-pickup-in-store (BOPIS), ship-from-store, and same-day delivery. As a result, retailers must transition from siloed inventory systems to a unified inventory visibility framework. This requires real-time data integration and advanced inventory management systems capable of tracking stock across warehouses, stores, and in-transit locations. The inability to achieve accurate inventory visibility can lead to stockouts, overstocking, and poor customer satisfaction. One of the primary logistical challenges in integrating offline and online channels is the complexity of order fulfillment. In an omnichannel environment, orders can originate from any channel and be fulfilled
