In the e-commerce era, customer expectations are skyrocketing. Businesses must optimize every stage of the supply chain to meet demands for fast, transparent, and convenient delivery. To achieve this, merging the middle mile (bulk transportation between warehouses) and the last mile (delivery to the end customer) is crucial. This unified approach unlocks benefits that enhance customer experience, including real-time tracking, faster delivery, cost savings, better demand forecasting, and more tailored fulfillment options. Overcoming integration, data sharing, and standardization challenges is necessary to realize the full potential of this transformation.
