This article deals with trust from a supplier’s point of view. Different supplier roles develop differently when examined from views of risk, power, and development and change in the trust relation. In this article trust is viewed as a sensemaking process and is found to have different implications in different supplier roles. Power and risk have different meanings, influenced by the differences in supplier roles. Development in the relation takes place with different presumptions, and has different courses as well as contents in relations between suppliers and buyers. Finally, the development of trust does not happen in a linear way in all types of relations. Instead, it rather happens in a discrete way.
