The propositions are derived largely from the preceding theoretical discussion, including Figs. 1 and 2. The aim is to lay the grounds for future research on interpersonal attraction, but in a buyer–supplier exchange context. Although the propositions are framed for the buying person/organization, the same relationships are proposed for the sales person/organization.

Much of the essence and promise of attraction research lies in the opportunity for increasing the other party's attractiveness by increasing one's own attractiveness. In addition, P3 links the interpersonal and interorganizational levels, jus- tifying the increased efforts at trying to understand interpersonal attraction as a means of improving business at the interorganizational level.
