Doing Business with the County

Supplier Portal

The County of Sonoma began using a new electronic procurement system for goods and services in February of 2015. 

You must register in the new Supplier Portal in order to:

  • Receive emailed notifications of  new County Bids and RFP’s
  • Review and bid on County issued solicitations
  • Review awarded contracts, purchase orders, invoices, and payments

Instructional documents to assist with registration, account maintenance, and bidding are posted on the Supplier Portal.
