Local delivery used to run on paper manifests and a driver’s memory of the neighborhood. That model is gone. Software now decides which truck goes where, which order ships first, and how a customer gets notified when their package is three stops away. The shift isn’t cosmetic. It changes cost structure, staffing, and customer expectations at the same time. The final leg of delivery, from a local hub to the customer’s door, has always been the costliest part of the supply chain.
