A method for using proxy checkout services is discussed. The method includes accessing transaction details of a potential transaction for an item or a first service at a merchant, the potential transaction initiated by a user at a user device at a first location. The method includes responsive to a determination, based on merchant characteristics or user characteristics, that use of proxy services is permitted, initiating proxy services for performing the potential transaction at different user locations. The method includes determining, based on selection criteria, a particular proxy service from the proxy services for initiating a proxy transaction based on the potential transaction using one of different user locations. The method includes causing a user interface of the user device to render a user-selectable option for performing the proxy transaction instead of the potential transaction.
