Supplier Guide

It is the policy of TAA to provide for the purchase of quality goods, materials, non-professional services and supplies at the lowest possible cost, while maintaining appropriate quality standards; maximizing administrative efficiencies; complying with all applicable legal and contractual requirements; and promoting appropriate opportunities for competition.

Purchases of Goods or Services Under $5,000

Informal, small purchases of less than $5,000 may be purchased without competitive quotes if the prices are considered to be fair and reasonable. These purchases are to be distributed among qualified suppliers.   

Purchases of Goods or Services Between $5,000 and $50,000

Purchases over $5,000 and up to $50,000 are made in the open market, without newspaper advertisement or other formal procedures. These purchases are based, whenever possible, on at least three (3) informal written or verbal competitive quotations, and are awarded to the supplier with the lowest most responsive and responsible quote.  

Purchases of Goods or Services Over $50,000

Purchases over $50,000 are done on a more formal basis including the use of formal sealed bids or Request for Proposals. These purchases are characterized by a public advertisement, generally in the Arizona Daily Territorial, and a public bid opening.   

Supplier Visits

To create a fair, quality-oriented, and cost-effective relationship between TAA and the business community, the Authority is committed to developing open communication with suppliers. Suppliers should make initial contact with Purchasing by mailing, e-mailing, or dropping off product literature and contact information. Suppliers may then follow up with a phone call for an appointment. TAA encourages all suppliers to take advantage of this opportunity to meet to discuss any new products or services, cost-saving measures, and changes in the industry. 

Warehouse Delivery

Every purchase must be received through the TAA warehouse. TAA staff will document receipt of shipment(s) on the order, determine compliance with specifications, inspect for damage. 

Supplier Payment

The Purchase Order is the Authority's legal and official document authorizing the supplier to deliver the specified supplies, materials, equipment, or service. Purchase Order numbers are only issued by Purchasing Department staff. Suppliers doing business with TAA should be aware that providing goods or services to any TAA department without first receiving a Purchase Order number will severely delay or may result in payment being denied.
