Purchase Orders

The Tempe Elementary School District conducts the business of purchases through the use of authorized Purchase Orders. The Purchasing Department has the sole authority to order supplies, materials, equipment and to obligate the School District for contractual services through the use of a valid Purchase Order. 

The schools and departments within this District do not have the authority to make revisions to a Purchase Order. The substitution of items without the prior written approval of our Purchasing Department is prohibited. Only those items specifically listed on a Purchase Order may be delivered. 

No authorization, verbal or otherwise, to deliver merchandise and/or services is given without an authorized Purchase Order. Any vendor or person who delivers merchandise and/or services to the District without an approved Purchase Order is at risk of not receiving payment.
