A purchase requisition is an electronic or paper document that makes an internal customer’s request for a purchased product or service official. How a requisition is processed will depend on the procurement technology available in your organization as well as the characteristics of the requested purchase. For example, if the request is for a commonly purchased item from a contracted supplier, your organization’s source-to-pay system may automatically convert the requisition to a purchase order and dispatch it to the appropriate supplier without any manual intervention from the procurement department. Or, if the request is for an expensive service that has never been bought by your organization before, you may want to begin a sourcing process at Phase I of the NLPA’s “10 Phase Approach to World-Class Sourcing.”
