The Leander ISD Purchasing Office is responsible for the centralized procurement of the supplies, materials, equipment and services that are necessary for our schools and offices to function. The Purchasing Office uses a variety of methods to contract for goods and services including the issuance of formal and informal solicitations, validation of exempt purchases such as sole source, and use of cooperative purchasing alliances. Contact information for Purchasing Office staff is listed in the directory below.

Doing Business with Leander ISD

Leander ISD utilizes Ion Wave Technologies as its sourcing solution to electronically post solicitations, receive offers and interact with the vendor community. The Leander ISD Purchasing Department encourages all vendors to register in the Ion Wave system in order to be notified when applicable solicitation are issued. The system utilizes commodity codes to match vendors’ goods and services with open solicitations.

Registering in Ion Wave does not make a vendor “awarded” (formerly referred to as “approved”). For a vendor to be considered awarded, they must respond to, and be awarded under, a competitive solicitation that was issued by an entity such as a purchasing cooperative or another Texas school district with whom LISD has an interlocal purchasing agreement on file. See Cooperatives section below for a complete list.

This registration does not make you an awarded vendor.  Your registration gives us the ability to email you when a new solicitation is open for your goods and/or services based on your profile and the commodities you select at registration. Registration on this platform is required in order to submit solicitation responses.  You must submit a solicitation response and be awarded a contract in order to be an awarded vendor with Leander ISD. 

If you need assistance with registration, please visit the Ion Wave Supplier Support page.

LISD is not responsible for maintaining the accuracy of vendor’s accounts. We also encourage you to include more than one company “User” when you register. This will ensure that at least one person in your company receives bid notifications. 

Note: If you are registered with any other agency using the IWT bidding system, you will not be able to reuse a previous user login name. You must create a unique user login name during registration. We recommend using a format like abcsupplies customer, where customer is a short version of the agency you are registering with.

Open Solicitations

Check out our current solicitations available based on goods/services your company provides. We look forward to viewing your response and possibly working with your company in the near future.

Note for Solicitations identified as Continuous RFPs: During the period a continuous solicitation is available for a response, the District’s Purchasing Department may need to make it unavailable so that no access can be made by vendors. This is done so that evaluations can be done. If a vendor has begun a response but has not completed it while the solicitation is unavailable, the unsubmitted response cannot be accessed, however, the previous information will not be lost. Once the solicitation is extended, the vendor will have access again to their incomplete response.
