The Purchasing Department is responsible for developing and administering consistent, fair and effective purchasing practices while providing service to all Washington District schools and departments. Its goal is to obtain the maximum value for every dollar spent while complying with the procurement policies set forth by the WESD Governing Board, the Arizona Administrative Code, the Uniform System of Financial Records, and Arizona Revised Statutes. In an average year, WESD issues approximately 6500 purchase orders. All purchases that involve public money are subject to the purchasing thresholds and procedures based on these thresholds. 
    Once the District reaches $10,000.00 in expenditures for any given vendor or in any given commodity during the fiscal year, each subsequent purchase must be covered by written price quotations until the District reaches the threshold for bids and RFPs.  Written price quotations must be obtained from at least three (3) vendors. The District may also elect to follow a more restrictive pathway, and either issue a formal solicitation of its own or piggyback off a cooperative contract.
    FORMAL SOLICITATIONS (Invitations for Bid/Requests for Proposal)
    For purchases that are anticipated to exceed $100,000 in any given commodity during the fiscal year, the District must either conduct a formal competitive sealed process or utilize a cooperative contract for the purchase of requested goods or services.   WESD utilizes an online service to maintain our Prospective Bidder’s List and to issue these formal solicitations.  The Purchasing Department also performs due diligence on any Cooperative contract to verify compliance with Arizona Procurement rules prior to the purchase.
    WESD maintains its prospective bidders list at www.azpurchasing.org. If you would like to be notified of open solicitations, please register at www.azpurchasing.org. This is the only system WESD uses for solicitation notifications and registration is free of charge for all vendors.  The District encourages participation by all businesses in our solicitation process, including but not limited to local businesses, small businesses, minority-owned firms, and women’s business enterprises.  
    Arizona Purchasing provides purchasers with web-based tools to more efficiently manage prospective bidders and solicitations while providing effective communication to the vendor community. The website serves purchasers across different disciplines for the purpose of developing a central and statewide prospective bidders list, posting solicitations and requests for quotations online, and more effectively disseminating solicitation information to the vendor and varied buyer communities.
    Vendors that have received an award through one of the formal competitive processes (Bid, RFP, RFQ) or informal processes (WQ) are considered a Contracted Vendor.  The District encourages the use of Contracted Vendors before the utilization of non-Contracted Vendors.  This helps us comply with Arizona School District Procurement Rules, as well as offering the District the benefits of discounted pricing, discounted shipping rates, and contract terms to help guide the purchasing process. Contracted Vendors can receive awards from WESD-issued solicitations, or through a cooperative contract. 
    Cooperative purchasing means procurement conducted by, or on behalf of, more than one public agency or governmental entityArizona School District Procurement Rules authorize and govern intergovernmental procurements, and in order to take advantage of these cooperative contracts, a signed intergovernmental Cooperative Purchasing agreement is required. Cooperative contracts benefit its members by helping to reduce administrative costs, reduce duplication across public agencies/governmental entities,  promote "best value", and are used to obtain economies of scale, leading to cost savings.
    WESD is a member of and participates in the following purchasing consortiums: 1 Government Purchasing Alliance(1GPA), Arizona State Procurement Office(SPO), Choice Partners, Greater Phoenix Purchasing Consortium of Schools (GPPCS), Mohave Educational Service Cooperative (MESC), Omnia Partners (OMNIA), and Strategic Alliance for Volume Expenditures(SAVE).   We utilize their contracts for purchases as well as our own WESD contracts. 
    Conflict of interest law prohibits WESD employees from identifying the need for goods or services from a business for which a relative works. “Relative” is defined as spouse, child, grandchild, parent, grandparent, brother or sister – whole or half blood, and their spouses and parents, or a brother, sister or child of a spouse. Additionally, the WESD employee is prohibited from selecting the business for goods or services, supervising the work of the business, voting on or approving the award of a contract to the business, and approving invoices for payment.  WESD employees are required to disclose any potential conflicts of interest on an annual basis. We ask our vendors to disclose any potential conflicts of interest when they register with us. 
    Any vendor wishing to be paid under a district purchase order must have completed a WESD Vendor Registration Form and a W-9 form.
    Purchases for WESD are authorized only by a Purchase Order (PO) signed by the Purchasing Administrator.
