Truly shared warehousing implies converting inactive, idle, and excess capacity of existing assets, warehousing space, into active revenue and profit by offering them to other parties. Although, truly shared warehousing is believed to be an innovative approach to tackle existing warehousing inefficiencies, it is not common practice yet. This contribution discusses truly shared warehousing in relation to the existing business models of warehouse-providers and shows the causes of reluctancy between parties to collaborate. Next, we examine the risks, challenges, conditions, and motivations for warehouse-space providers or facilitators and their customers to further use the concept of collaboration in relation to truly shared warehousing in particular. The results show that not all conditions and motivations are in place to really work together for logistics providers and platform providers.
