What are the main three types of organizational buyers? How are they distinct from one another? Solution The main three types of buyers are Resellers, Producers and Institutional buyers. Reseller include wholesalers and retailers who buy in large quantities from the manufacturers or at the point of production to sell to the individual customers at a profit. The producers are the manufacturers of certain goods or services that need several components to be sourced from different manufacturers who specialise in their production. The institutional buyers are Governments Hospitals or schools which buy in large quantities for their internal use. The three differ in the purpose of the buying and with regards of the use of commodities bought. The resellers buy to earn a profit by breaking the bulk and selling it in smaller quantities to consumers, whereas the producers buy the intermediate parts of their final product, because it is not economical for them to produce it in house. Institutional buyers do it to negotiate good price for bulk purchases at attractive conditions..
