Purchase Orders

We currently have several thousand vendors on our vendor list.  Before a vendor can be issued a MPS Purchase Order a copy of its IRS Form W-9 must be on file in our office. 


All commitments of purchases by MPS will be made by an approved Purchase Order number assigned by the Purchasing Department. Products/services are not to be delivered without an approved Purchase Order. Vendors accepting orders without a purchase order number do so at their own risk. 


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. The schools and departments within this district do not have the authority to substitute without Purchasing's approval. Verification of Purchase Orders may be made by contacting Purchasing.
