How to do business with us

As a Texas public school district, we abide by laws set forth by the Texas Legislature pertaining to large purchases. The laws are designed to ensure that public funds are used wisely.

Register for iSupplier

iSupplier is a portal program designed to provide suppliers the ability to view a history of purchase orders and invoices and serves as GISD's supplier collaboration network.

Completing the registration process is used to establish a database of interested suppliers and does not guarantee approval to provide goods or services to the Garland Independent School District. Remember to attach your completed W9 before clicking the register tab.

To register as a supplier with GISD, please login to the iSupplier online registration portal then submit the items referred to under "Documents required for registration" via email to bids@garlandisd.net:

Once all of the documents required for registration have been received and approved by the Purchasing department, you will receive an email with login information for the iSupplier network and be registered as a supplier for GISD.
