A method of optimizing multi-enterprise supply chain agreements using an electronic scenario based option contract includes creating at a buyer computer a plurality of scenarios of forecasted demand for one or more products and communicating from the buyer computer to a seller computer an offer to enter into an option contract for the supply of the one or more products, the option contract including an option corresponding to each of the plurality of scenarios of forecasted demand. The method further includes executing the option contract, receiving at the buyer computer an indication of current buyer demand for at least one scenario associated with the one or more products, and exercising at least a portion of the option in the option contract based at least in part on the indicated buyer demand.
