A practical communication and computer based system and method for effecting exchange, investment and borrowing involves the use of digital communication and computation terminals distributed to users and service providers. Through the system described and its combined computer and communication terminals, client/customers may purchase goods and services, save, invest, track bonuses and rebates and effect enhanced personal financial analysis, planning, management and record keeping with less effort and increased convenience. Through a prioritization function, the client specifies her financial objectives, her risk preference, and budgetary constraints. The prioritization function automatically suggests to the individual a portfolio of asset and liability accounts that may be credited and/or debited to provide the required funds for consumption and to form investments and borrowing to best realize her financial objectives over a defined time horizon. If desired, the system automatically manages a client's budgetary and financial affairs through a system of expert sweeps based on a client's preferences. The client's accounts are monitored via a borrowing power baseline, and considered imbalanced if the client's borrowing power is less than the minimum borrowing power. If the account is imbalanced, the client may reallocate the assets and liabilities within the client account and/or modify a set of constraints on the client account. If the client account is still not balanced after modification of the account, the system will deny authorization for certain requested transactions, and may initiate the liquidation of certain asset accounts and reduce the balances of one or more liability accounts.
