The sale of commissioned goods is an old, well-known concept although its implementation and automation in the context of the modern information systems in enterprises is not all that simple given that it implies appropriate contractual arrangement, and organizational and informational interaction between the enterprises involved in the commission sale. Notwithstanding the explicit and standardized legal framework for the commission sale system, its organizational realization and especially its information system design, has not been formally standardized. As a result, this creates a new issue and poses a challenge to each specific commission sale case. In view of the above, this paper provides a complete, functional and verified conceptual model of cooperative interaction between two enterprises in a spatially distributed system of a developed commission sale, supported by the ICT (information-communication technology). This model in practice should yield good results as it ensures optimal position to both the owner (Principal) and the seller (Commission Agent) of goods, from the point of view of competences, liability and risks related to the goods intended for sale.
