In an estimate information creating device, an estimate newly-creating section ( 4 ) obtains a negotiation-independent information address of an updated negotiation-independent information from a negotiation-independent information DB ( 5 ), and further obtains, from a negotiation-dependent information DB ( 3 ), user information, user demand information, and an ID of negotiation-dependent information having the obtained negotiation-independent information address and having a "contract-unconcluded" status. An estimate creating section ( 2 ) returns to the estimate newly-creating section ( 4 ) estimate information that conforms to the user demand information, and the negotiation-independent information address. After estimate information identified by the obtained ID is updated, the estimate newly-creating section ( 4 ) sends notification to a user terminal ( 1 ). In such a way, an estimate is newly created when estimate basic information has changed. |
