The 4PL cooperation model we offer is a model of entrusting the management of the entire supply chain to a logistics operator. Outsourcing in addition to services such as warehousing, packaging, stock control and documentation, customs clearance, insurance and returns handling translates in the 4PL model into our involvement in negotiations with cooperating external companies as well as providers of these services. As a 4PL logistics operator, we coordinate the work of those involved in the process within the supported supply chain in the 4PL model.
