Abstract: A system and method for providing real-time appointment rescheduling by providing access to one or more computer-based appointment scheduling systems and a virtual open appointment wait-list associated with one or more appointment slots in the scheduling systems. One or more service consumers request to be placed on the wait-list. When an appointment becomes available, wait-list data is searched to find the first consumer that is next on the wait-list and whose wait-list data is consistent with the newly available appointment. The first consumer is then contacted with a designated period of time to respond and accept the appointment. After the designated period of time has passed with no response from the first consumer, the wait-list data is searched again to find the second service consumer that is next on the wait-list. The process is repeated automatically until the newly available appointment is accepted.
