To solve problems in an account transfer wherein management is troublesome due to different debt transfer dates determined by each biller, a bank account is often insufficient in a debt transfer before pay day and vast expenses are necessary since bills are individually mailed by each biller.

In an account transfer of a financial institution or a post office, the collective money transfer system for the account is characterized by that it is provided with a money transfer request receiving means of receiving a request for an automatic debt transfer on a scheduled date of each biller, a managing means of storing and managing each piece of information of a biller, an amount billed and a money transfer date received by the money transfer request receiving means, a billing means of collectively billing the total amount of each amount billed managed by the managing means, and a debt transfer means of collectively transferring the amount billed by the billing means from the account.
