Vendor Self-Service (VSS) System

The City of Mesa has a new system to register and maintain vendor accounts. 
 
AMS Vendor Self Service (VSS) provides vendors with a single entry point to register, provide payment and contact information, and select commodity interests and business types.  All vendors who wish to conduct business with the City will be required to update and maintain all information used for the notification of bid opportunities and issuance of payment in the VSS system. 
 

Vendors currently doing business with the City of Mesa will need to activate their account.  Using your Company TIN, you will log in and establish a unique User ID and password and submit your registration.  Once activated, you will need to update your account by verifying the information on file and selecting your commodities. Please review the  Registration Guide for Active Vendors.
 

New vendors can register their company in the VSS application by providing their Legal Name, TIN, and company information.  A W-9 is required to be submitted in order to be considered an “active” vendor and one the City can do business with.  You must email your W-9 to the Purchasing office or fax to 480-644-2655.  Please review the Registration Guide for New Vendors.
 

Foreign vendors can register their company in the VSS application by providing their Legal Name, W-8 Form, and company information.  The W-8 will be required to be submitted in order to be considered an “active” vendor and one the City can do business with.  You must email your W-8 to the Purchasing office or fax to 480-644-2655.  Please review the Registration Guide for Foreign Vendors.
