The name given to the process of outsourcing in logistics is called 3pl. To make this concept a bit more understandable, it is useful to state why number 3 is used: Here the first is the sender, the second is the receiver, and the third is the logistics company that specializes in the field of bridges between the two companies. This is the third company where some or all of the logistics business is transferred for reasons such as cost and efficiency, and therefore its name is 3PL. For example, the sender A is the company and the receiver is the B company. Company P transports the products that company A will send to company B. Firm P mentioned here is a third firm apart from A and B firms and therefore 3 PL is mentioned in this process.
