Systems and methods for dynamic calculation and updates of values

Abstract:

A system for roll-up payments in a retail environment is provided. The system includes a processor coupled to a memory storing a wish list associated with a wish list user identifying an item, customer registration information identifying a registered customer associated with the wish list, and an amount of available funds associated with the wish list, an interface component configured to receive sales transaction information and provide updated sales transaction information, and a roll-up payment component. The roll-up payment component is configured to match identification information associated with the registered customer with the received sales transaction information, increase the transaction amount and the amount of available funds, determine whether the amount of available funds has transgressed a threshold amount equal to a purchase price of an item on the wish list, and generate a notification for the wish list user.
