A transportation management system is like an organized way to manage the different parts of transportation in a business. For example, a business may have a lot of packages they need to send to their customers. The transportation management system will help the business keep track of all the different packages, figure out the fastest way to get them to their customers, and keep a record of all the different deliveries. It helps the business make sure that all their packages get to their customers quickly, safely, and cost-effectively.
