The purchasing card is the University's secondary authorized buying method. The purchasing card functions similar to a credit card and is used for routine purchases. It expedites and simplifies the procurement process, reduces administrative costs associated with invoice processing, and ensures immediate payment to the supplier. It provides authorized employees who are delegated as departmental buyers with an effective tool to purchase and pay for routine, low dollar, non-restricted commodities from non-restricted suppliers.
