Logistics has increasingly been recognized as a vital part of an organization’s competitive resources. With an increased outsourcing of the logistics function, due to increasing competition and high customer expectations on service-level, there is a need for more professional and well-equipped logistics services. This need is emphasized by the tendency that competition increasingly takes place between supply-chains more than between companies. There is a development of actors, known as third-party logistics providers or logistics integrators, who can take the role as integrator for several companies in a supply chain. This article focuses on the driving forces of these actors and how they can stay competitive by providing customers specific logistics solutions. A case study is presented of a Logistics Integrator and three of its customers with a varying degree of integrated collaboration in the logistic chain, and some key issues are presented from the provider’s and the customer’s perspective.
