An electronic requisition processing method and system are disclosed. The method comprises the steps of preparing an electronic requisition including a requisition proposal; establishing an electronic list of approvers for the requisition; and at defined times, electronically recalculating the list. Preferably, this list is recalculated after each of at least some of the approvers act on the requisition; and the list is recalculated according to a given set of rules. Also, in the preferred system, the approval process is synchronous, whereby upon submission of the requisition, the requisition is immediately available for approval. Additionally, preferably, when each approver approves, the list is dynamically recalculated to take into account the availability of approvers further down in the list.
