Last-mile delivery is the final phase of the delivery process. In a product’s journey, it is moved from the warehouse shelf (often at a distribution center), to the back of a truck, to the customer’s doorstep—the final step of this process, known as the last-mile of delivery. High shipping costs are often associated with last-mile delivery.

While last-mile delivery is the most expensive and time-consuming part of the shipping process, it is key to overall customer satisfaction.
