Doing Business with Southwest ISD


The Purchasing Department is responsible for the acquisition and contract of all supplies, materials, equipment and/or services for the District.  Southwest ISD assumes no liability for payment obligations except those incurred according to its purchasing policies.  An official purchase order that has an authorized purchase order number affixed thereon is the only method for the purchase of supplies, materials, equipment and/or services obligating Southwest ISD to payment.  A purchase order provides official authorization before a purchase is made. 



The Southwest ISD will issue purchase orders as the only method for all business transactions.  Payment will be generated within 30 days after the items or service is received along with an original invoice.  PURCHASE ORDER NUMBER MUST BE INDICATED ON ALL INVOICES.  NO BACK ORDERS OR COD SHIPMENTS ARE ALLOWED! Price increase must be pre-approved by contacting the Accounting Department at 210-622-4300.
