How We Do Business

  • We extend a warm welcome to those wishing to do business with the Sherman Independent School District (SISD or the "District").  It is our goal to make our relationship friendly and mutually rewarding.  Our principal objective is to acquire goods and services at a fair and reasonable price.  We are constantly seeking new sources and welcome your participation.   

    Prospective vendors are encouraged to register with the online SISD Bids and Contracts System.


    The Sherman Independent School District, as well as all other school districts in the State of Texas, is governed by the state competitive bid law. Therefore, the majority of our purchasing is done via competitive sealed proposals.

    The purpose and intent for the competitive bidding process is to help public schools obtain the best products at the lowest practical prices in the best interest of the taxpayers by stimulating competition. The Sherman ISD is committed to fair and equal competition among all vendors. In addition, the state competitive bid law does not allow favoritism to be shown to any vendor.


    To ensure your company is included on our bid lists, please go to the SISD Bids and Contracts System to register your company. 

    This registration is not intended to add a vendor to the awarded vendor list, but to make sure all those that desire to be a part of the process get notified of bid opportunities.


    Sherman ISD is a member of numerous purchasing cooperatives in the state of Texas. These include the Texas Building and Procurement Commission, Texas Cooperative Purchasing Network, and Educational Purchasing Cooperative of North Texas.

    With e-bidding, vendors will:

    • Register to receive notifications of upcoming bids in vendor’s prospective fields
    • Complete and submit bids online
    • Review bid tabulations and awarded bid information online

    Vendor pays no fees for utilizing the online bidding system. 

    When entering the company Tax ID number, do not enter any dashes, only numeric.  All information can be submitted electronically.  It is not necessary to print any forms and fax to the purchasing department. 

    It will be the sole responsibility of each vendor to maintain and keep current their company's information on the District's e-bidding site.  In the event of a contact person name change, address, phone, etc., it will be necessary for the vendor to edit their company information on the e-bidding site.  

    Passwords can be reset by using the "Forgot your Password" function.  If the original user is no longer associated with your organization, then contact SISD's Purchasing department by calling 903-891-6438.  It is understood that all bid notifications will be sent to the e-mail address on file and it is imperative that the vendor information be kept current.  Otherwise, bid notifications will never be received by the vendor and the opportunity for bid submittal will be lost.

    ** You must submit a supplier registration form on this site to access all online bidding opportunities and to receive any purchasing notifications.**


    The Supplier Registration is used to identify vendors who desire to participate in the competitive bidding process.  This registration is not intended to add a vendor to the awarded vendor list, but to make sure all those that desire to be a part of the process get notified of bid opportunities.  Vendor approval status is based on the awarding of bids and proposals. Submittal of the Supplier Registration does not imply or guarantee to the submitter the receipt of any invitation to bid or request of proposal released.   

    SISD has a partnership with IonWave, an Online Supplier Registration and web based eProcurement service.  Prospective vendors are encouraged to register their companies on the SISD Bids and Contracts System.  Registration is not required to access the bid documents.  If you wish to respond electronically, registration will be necessary.
