Vendor Information

How to Become an MISD Vendor

The McKinney ISD Purchasing Department encourages and welcomes all vendors to become an MISD vendor. Vendor participation is an extremely important aspect of the entire purchasing process. We request that all vendors interested in supplying products or services to MISD, complete a Vendor Application and return to the Purchasing Department via fax to 469-302-4139. The application allows Purchasing to place your company on the bid list with the appropriate commodities and/or services your company provides. If McKinney ISD does not have a W9 on file, you may be required to fill out a W9. McKinney ISD personnel will contact you if it is necessary for you to fill out this form.

Bid and Proposal Notifications

McKinney ISD advertises bids and proposals in the McKinney Courier Gazette once (1) a week for two (2) consecutive weeks prior to bid/proposal opening. Also, bid notices are mailed to vendors from our bid database notifying them of bids and proposals posted on our website that may be accessed by selecting the Bids link from this page or at the bottom of the Purchasing home page. Vendors must respond to bid/proposal/quote invitations or return a Notice of No Bid Form to remain on our bid list. Vendors may also be removed from the bid database for unsatisfactory vendor performance.

Award Notification to Successful Vendors

Award letters are mailed to successful vendors after Board approval, usually the fourth Tuesday of each month. Notification of award does not guarantee, nor initiate a purchase. Purchases will be made with an authorized McKinney ISD purchase order based on available funds. Vendors must assume responsibility for any items/services that are purchased without an authorized McKinney ISD purchase order.
