Abstract: Using a single source money management system customers may automate their committed spending. A money management account and a discretionary fund account are established in response to a customer's request to participate in the system. A financial institution receives money on a periodic basis from a customer's predictable payment system. The money is then deposited/transferred to the money management account, retained in the money management account as required for bill payment, and/or deposited/transferred into the discretionary fund account if it is “excess.” Bills are paid on a customer determined schedule directly from the money management account using the money retained in the money management account. A loan account may also be established in response to a customer's application for a loan account. A financial institution grants a loan for a loan purchase in response to a customer's application for a loan purchase.
