Tender

In the context of shipping, a tender is a request for proposals or bids from shipping companies or carriers for the transportation of goods. A tender typically includes information such as the type and quantity of goods to be transported, the origin and destination of the shipment, and any special requirements or conditions. 

Shipping companies can then submit proposals or bids in response to the tender, and the shipper can choose the best option based on factors such as cost, transit time, and level of service.
