A delayed transaction method and system to handle multiple delayed transactions in a PCI system is disclosed. When the responder accepts a first and second request from an initiator but can not immediately respond to the first and second request, the responder generates a first and a second defer identifier corresponding to the initiator, respectively. When data transfer between the responder and the initiator corresponding to the first request is completed and data is ready for transfer corresponding to the second request, the responder immediately issues a second buffer identifier along with the data requested corresponding to the second request. Thus, data transfer between the initiator and the responder based on the second buffer identifier corresponding to the second request can proceed.
