Abstract: The present provides a mechanism of leaving, as a record, a fact that a correction of order details of an accepted order is proper in virtual shopping mall service. When modification of order details is received from a member store terminal 40 (S615), a virtual shopping mall management server 10 calculates the difference between an amount before the change and an amount after the change. When the difference is determined to be equal to or larger than a predetermined amount (Yes in S620), the server generates a settlement process request page and transmits it to the member store terminal 40 (S625a). When the settlement process request information is received from the member store terminal 40, the server transmits an e-mail requesting for approval on the change in the amount to a member terminal (S630a).
