This system is preferably performed as software. According to this system -- a group -- a tenderer can present a bid by interactive mode on a computer or a communication network. These bids are memorized by the system and the information on the newest auction situation is always given to a tenderer. A system is kept shut for the further bid to an auction at the suitable time, and notifies a successful bidder and a successful bid failure of it as a result of an auction.
