The purpose of this paper is to illustrate an effective coordination process in the B-to-B section of a supply chain. In particular the paper focuses on the interactions between a supplier of raw materials and a buyer processing them into end products in the food industry. These interactions are governed by a delivery contract. Under the terms of the current contract a season's entire crop is purchased at time of planting at an unit price per pound regardless of volume and quality delivered. This simplicity of the contract is an attractive feature of the interaction in the Bto-B section.It is shown that the supply chain's optimum cannot be realized with a single price. From several alternatives a pricing scheme is proposed in which prices are related to quality. The goal is to determine prices which facilitate the supply chain's maximum performance assuming rational behaviour of the supplier and the buyer. Conditions for realizing the supply chain's maximum are formulated and an approach is presented which generates a significant improvement in performance.
