Always verify on the official posting. Agencies change dates, issue addenda and cancel solicitations. BidLasso compiles public information and is not affiliated with, endorsed by, or acting on behalf of any agency.

Where Williamson County posts bids

Williamson County uses Bonfire for all quotes, invitations for bid, RFQs and RFPs, and registration is free (Supplier Information). The County still accepts paper bids if they are time-stamped in the Purchasing Office before the closing time, and it advertises bids in the local Sunday newspaper at least two weeks before the opening. BidLasso does not collect Bonfire postings, so register there for the County's own notices.

Williamson County Purchasing: 100 Wilco Way, Suite P101, Georgetown, TX 78626, 512-943-3553, [email protected].

Open items located in Williamson County

These come from the boards BidLasso does collect (City of Austin and TxDOT), not from the County's own portal.
