SAP Ariba


The City of Tacoma uses SAP Ariba for its procurement processes.  SAP Ariba is an eCommerce website that facilitates procurement. It allows us to securely collect our vendors’ information and streamlines buyers’ and sellers’ ability to connect and find each other.


SAP Ariba enables electronic sharing of procurement-related documents like bids, contracts, purchase orders, and/or invoices. For more information, view our Frequently Asked Questions.                                       

Register in SAP Ariba and complete the City of Tacoma profile questionnaire.  Once your registration is received, it will be reviewed by the City of Tacoma Finance Department, Procurement & Payables Division and you will be notified of your approval status. When all the needed information has been provided, your organization will become approved as a supplier.
