A transport broker acts as an intermediary between shippers and carriers. They connect shippers with carriers to facilitate the transportation of goods. Brokers do not own the transportation assets themselves. They negotiate and arrange transportation services on behalf of their clients.
While carriers are the actual providers of transportation services. They own and operate the trucks, ships, planes, or other means of transportation.
