Supply chain integration is divided into two dimensions, namely internal integration and external integration. Internal integration refers to cross-functional collaborative processes within the company. External integration consists of the integration of suppliers, the integration of customers and logistics service providers. Sometimes external integration works best if the company has good internal integration. On the other hand, the lack of internal integration is the cause of external integration and the realization of the supply chain. For this reason, the present work aims to investigate the integration between two fundamental functions: logistics and marketing. Both are strategic because their performance directly affects customer satisfaction. Studies investigating this relationship are still limited in number. Therefore, this document aims to examine whether functions share information on processes such as new product development, package redesign, promotions and product returns. The literature, in fact, highlights that the lack of integration leads to an increase in operating, inventory management and transport costs. Through an online questionnaire, this paper analyzes the state of the art in 83 Italian companies. The results confirm the low rate of integration between logistics and marketing not only in small and medium-sized enterprises but also in large companies.
