The present invention integrates a credit card account with cash account through an electronic wallet application such that cash can be transferred directly into a user's cash account after each transaction which cash back is earned. In some embodiments, the user's cash account and a cash account associated with a business associated with a credit card can be provided by the same financial institution. The above infrastructure further allows for more efficient payment of a credit card balance, wherein when cash is transferred from the user's cash account to the business' cash account in association with a credit card balance, an immediate release of open to buy funds is affected.
