How to register as a Bexar County vendor

Bexar County sends bid notifications by commodity code. Register once, pick the right codes and the County's notices come to you.

Updated October 22, 2026

Bexar County Purchasing uses an Infor (Lawson) Supplier Portal. According to the County's Supplier Portal / Vendor Registration page, registering gets you automatic bid notifications for the commodity codes you select, and it is also required for payment. You'll need a signed W-9 for payments.

Heads-up: BidLasso does not currently collect Bexar County notices automatically, so registering for the County's own notifications is the best way to catch them.

Step by step (from the County's instructions)

  1. From the Supplier Portal page, choose Register as a Supplier and accept the Terms and Conditions.
  2. Create your account. The user name is case-sensitive, with no spaces or special characters. The County suggests not using a personal name, because it can't be changed if that employee leaves.
  3. Enter your details and company information in CAPITAL LETTERS, as the instructions ask.
  4. Demographic codes: select one each for ethnicity, disability, gender and business size, or "Do Not Wish to Disclose".
  5. Commodity codes: search by keyword. A 3-digit top-level code notifies you for everything under it. A 5-digit sub-code is narrower. This step decides which bid notices you get.
  6. Optionally add proxy notifications so a coworker also gets the emails (proxies can't submit).
  7. Note your Supplier Number when registration completes.

Responding to a Bexar County bid

  1. Log in and choose Browse Open Events. Check each event's open and close dates.
  2. Open the event, review every tab and attachment, then Respond Now and accept the event's terms.
  3. Answer each line, the questions and the attachments (the County lists a 300 MB attachment limit), then Submit.
  4. Changes must be made before the close date and time, and you have to click Submit again after any change.
