A bank account that is operated so that it contains no funds on deposit at the end of each banking day. Corporate bank account holders use zero balance accounts in conjunction with other bank accounts as part of a process referred to as cash management (or treasury management). Zero balance accounts are used only as a means to make or receive payments. When a check is presented against a zero balance account, the account bank automatically transfers the exact amount of funds required to clear the check into the zero balance account from another of the company's bank accounts (such as its investment account or general checking account). If funds are paid into a zero balance account, at the end of the day on which the funds are credited to the account they are swept into another of the company's bank accounts (such as its investment account) leaving the zero balance account with no funds on deposit.
