A remote purchase controller for a remote purchase electronic payment account has absolute or periodic limits associated with one or more authorized account users. When a remote purchase transaction would exceed the available limit for a requesting user, including any associated over-draft margin, some form of override of the limit is sought, such as by direct override approval or by allocation of at least a portion of the remote purchase transaction amount against another user's limit. If the limit remains, the remote purchase transaction is held until the beginning of a next period, when the transaction may be either automatically executed or submitted for reapproval by the requesting user.
