You submit a requisition before you make the purchase (and certainly before the goods have been delivered.)
When will I use a requisition? - Requisitions are only used to pay amounts of $5,000 or more. If the amount is less than $5,000, you should use the Baylor Purchasing Card if at all possible.
How do I submit a requisition? -- Here are the main steps to using a requisition. Be sure to complete all the steps, or Procurement Services will not be able to issue a purchase order.
Note: For purchases of $25,000 and higher TRAX will automatically route the requisition through the budget office for approval before a purchase order can be created. This will add some time to to the process.
