Historically, shipping companies have paid their freight bills based on the standard parameters of freight rates and transportation schedules.The forwarders, which offer shipping services to the products forwarders, are made up of several shipping companies and smaller goods forwarders. These commodities forwarders move cargo from ships to manufacturing plants, storage facilities, and other places where goods are kept and sold. As the goods forwarders do all of these duties, the forwarding corporations that oversee them earn a small percentage of the profits. Some goods forwarders provide more services than only goods forwarding, such warehousing.
