A logistics consultant helps companies optimize their supply chain and logistics operations by providing expert advice and recommendations. They analyze a company's current logistics systems and processes, identify areas for improvement, and develop strategies to enhance efficiency and reduce costs.

A logistics planner, on the other hand, is responsible for developing and implementing logistics plans for the movement of goods and materials. They coordinate with suppliers, transportation providers, and other stakeholders to ensure that shipments are delivered on time and within budget. The goal of a logistics planner is to optimize the flow of goods and materials, minimize costs, and improve overall supply chain efficiency.
