In response to a confirmation request of an electronic quotation with respect to a specified product sent from a client PC 50 via the Internet, an electronic quotation system 10 reads electronic quotation information including a product quote, a delivery date, and a valid period from a database 30, and determines whether the electronic quotation is still in the valid period or the valid period of the electronic quotation has already expired. When it is determined that the electronic quotation is still in the valid period, an electronic quotation window including an 'Order' button is sent back to the client PC 50. When it is determined that the valid period of the electronic quotation has already expired, on the other hand, an electronic quotation window including an 'Update' button for updating the electronic quotation, instead of the 'Order' button, is sent back to the client PC 50. The electronic quotation system 10 of the invention readily determines whether the electronic quotation is still in the valid period or the valid period of the electronic quotation has already expired. Even after expiration of the valid period, the arrangement of the invention does not require a client to re-enter the electronic quotation information all over again.
