Final mile logistics definitions

Let's start from the basics, break down the last mile industry's buzzwords, and explain what they really mean.

Last Mile Delivery (LMD) or Final Mile Delivery

The final leg of the delivery process where goods are transported from a transportation hub or fulfillment center to the customer's doorstep or preferred location.

Final Mile Logistics

The specialized logistics operations and strategies focused on the last mile delivery, such as optimizing delivery routes, managing inventory, and coordinating with local couriers or carriers.

Third-Party Logistics (3PL)

3PL refers to the outsourcing of logistics and supply chain management activities to a specialized external service provider.  A 3PL company acts as an intermediary between businesses and their customers.

Customer Experience (CX)

The overall impression and satisfaction that customers have during their interaction with the delivery service, including factors such as communication, timeliness, and professionalism.

Route Optimization or Route Planning

The process of building the most efficient delivery routes to minimize time, distance, and fuel consumption. The route optimization process often involves advanced algorithms and final mile software solutions.

Dynamic Route Optimization

Dynamic route optimization in last mile refers to the real-time adjustment of delivery routes based on changing factors such as traffic conditions, weather, and order additions or cancellations.

Static Route Optimization

Static route optimization in final mile delivery involves the pre-planning and optimization of delivery routes based on historical data, known traffic limitations, and set parameters. 

Courier Dispatch

Courier dispatch refers to the process of assigning and dispatching couriers or delivery personnel to fulfill specific last mile delivery routes or orders. Final mile delivery management software is typically used for courier dispatch.  

Tracking and Tracing

The ability to monitor and trace the progress of a delivery in real-time, providing customers with live updates and visibility into the location and estimated time of arrival of their package.

Delivery Window or Delivery Time Slot

A specific time frame during which the customer expects to receive their delivery, typically provided to them in advance for planning purposes.

Delivery Driver App

A driver app refers to a mobile application designed and used by last mile delivery drivers. Delivery driver app often comes as a part of final mile delivery software. It provides couriers with essential tools to manage their daily tasks effectively.

Driver apps typically offer features such as load and vehicle checks, GPS navigation, delivery tracking, communication with dispatchers, proof of delivery capture, barcode scanner, and access to relevant shipment details.

Proof of Delivery (POD)

Documentation or evidence in the final mile that confirms the successful delivery of a package. Final mile POD often comes in electronic format - ePOD. ePOD is obtained through e-signatures, photo proofs, geotags, or custom notes.

Reverse Logistics

The process of handling returns and managing the flow of products from the customer back to the retailer or manufacturer. Unlike the traditional forward logistics, which focuses on moving goods from the warehouse to the end customer, reverse logistics handles the movement of products in the opposite direction. 

Load Check

It is a critical step in the last mile logistics operation to prevent delivery errors, misplaced packages, or missing items during transit.

Order Fulfillment

Order fulfillment in final mile refers to the comprehensive process of receiving, processing, and delivering customer orders from the final distribution center or warehouse to the intended recipients, typically within the local delivery area. It involves picking the items from inventory, packing them securely, and coordinating their delivery through efficient route planning and real-time tracking.

Redelivery

Delivery attempts that are made again in the event of a missing or failed delivery, a rejected order, or other circumstances. It occurs when the recipient was unavailable, the delivery address was incorrect or inaccessible.

Planned vs Actual Mileage

Fleet Capacity Utilized

Metric in last mile logistics that refers to the percentage or measurement of how effectively an organization utilizes its available fleet resources. It shows how much the fleet's vehicles and delivery staff are being used to their fullest potential to fulfill customer orders.

Fuel Consumption Rate (FTR)

A performance metric that measures vehicle fuel efficiency in miles per gallon (MPG) or liters per kilometer (L/km). This fuel efficiency statistic helps logistics businesses examine their transportation activities' environmental impact and operational expenses.
