The present invention is to provide a computer system, and a method and a program for settlement that are capable to restrict the place where the settlement of business expenses can be made and to gain approval of the settlement according to workflow. The computer system checks whether or not the current location of a terminal is previously registered; and restricts the terminal from performing a purchase settlement process if the current location of the terminal is not previously registered. Moreover, the computer system receives a credit-card settlement request associated with an approval flow in which an approver makes credit-card settlement, suspends the settlement without making the settlement even if the receiving unit receives the settlement request, requests an approver in the approval flow to approve the settlement, and makes the settlement suspended by the suspending unit on approval from the approver.
