Systems and methods consistent with the present invention manage a credit card having an adjustable credit limit. The system determines whether the credit limit is likely to be reached by possible transactions made by the customer when using the account. The system adjusts the credit limit when it is determined that the credit limit is likely to be reached. The adjusted credit limit is analyzed to determine whether it satisfies predefined credit limit amount criteria associated with the account. The system then revises the adjusted credit limit, as necessary, such that the revised credit limit satisfies the predetermined credit criteria.
