The McKinney ISD Purchasing Department encourages all vendors to become registered with MISD. Vendor participation is a critical part of the purchasing process. Prospective vendors are invited to register with the McKinney ISD e-Bidding System.

Our goal is to identify vendors who wish to participate in the competitive solicitation process, which may include bids, proposals, quotes, or requests for qualifications. Registration does not constitute placement on an approved vendor list; it ensures that interested vendors receive the appropriate invitations to participate in these opportunities. Vendor approval status is determined based on solicitation awards, in accordance with purchasing guidelines.
