What is Logistics?

Logistics is the process of planning, executing, and managing the efficient movement of goods, services, or information from origin to destination. It includes everything from transportation and warehousing to inventory control, packaging, and delivery.

In short, logistics ensures the right product reaches the right place, at the right time, and at the right cost. For businesses, efficient logistics means faster delivery, lower costs, and improved customer satisfaction.

Logistics vs. Supply Chain

While they are often used interchangeably, logistics and supply chain management are distinct:

  • Logistics focuses on the movement and storage of goods.

  • Supply Chain Management is the broader process of overseeing the flow of raw materials, production, logistics, and customer service.

Think of logistics as the engine that powers the supply chain.
