A business partner overall power judging system applicable to a bidding system in which a business partner presents a bid price through a network in response to presentation of an object by a buyer company. The business partner overall power judging system comprises a business partner database where numerical data on the power of the business company is stored. A controller of the business partner overall power judging system reads the numerical data on the business partner from the business partner database in response to reception of a bid price and selects a business partner for the object on the basis of the bid price and the numerical data. The controller can give a weight to the power of the business partner with respect to the object of the bidding. The selection of a business partner can be based on the weighted power. A business partner most suitable for the object of the bidding can be selected in consideration of not only the bid price but various powers of the business partner.
