A written instruction by a current account holder to his bank to debit his account at regular intervals with a specified amount for a given period is known as a "standing order". This is a type of automated payment arrangement that the account holder sets up with the bank to make recurring payments, such as rent, mortgage, or utility bills, without having to initiate each payment separately. The standing order is initiated by the account holder, and the bank automatically debits the specified amount from the account and transfers it to the designated payee at the scheduled intervals.
