  • Vendor Self Service System (VSS)

    Please contact Vendor Relations at (520) 724-8465 if you have questions or need assistance with creating or updating your account.

    The Pima County Vendor Self Service System allows you, as a Vendor, to manage your account information, view your financial transactions and much more. Click on the Vendor Self Service Portal (VSS) link below to begin the electronic application process to register as a Vendor or to update your existing record. Please disable your pop-up blocker to access all site areas.

    Vendors MUST register at least 48 hours in advance AND submit a signed W-9 Form to the Vendor Relations Coordinator to fully activate your account.

    If you believe you are already registered as a vendor, select the VSS link below, select 'Register' and search for an existing account using your TIN or business name (for a business) or last name and SSN (for an individual).
