How to make a 3-quote buy

Check the Available Contracts list. If there's a universal contract, use that instead of the 3-quote process.

If there’s no contract available, continue:

  1. You must request at least three (3) quotes from registered King County suppliers.

  2. Search for suppliers by name, or by commodity. You will need to login and go to the Vendor Search tab.

  3. Make sure the quotes compare similar features (“apples-to-apples”), then award to the lowest bidder.

  4. Pay with your P-Card whenever possible.

Legal Requirements for 3-Quote Buys

  • For purchases between $10,000 - $50,000 you must request quotes from at least three registered King County suppliers. If possible, at least one quote should be from a certified King County Small Contractor or Supplier (SCS) firm.

  • If there are not three suppliers registered with King County, you may contact other suppliers for quotes.

  • Quotes must compare similar features, "apples-to-apples."

  • Always award to the lowest bidder.

  • Purchase limits apply to the total cost of like goods and services you intend to buy within a calendar year (January - December) per cost center.

    "Like" goods and services are anything a reasonable person would describe as similar. "Intent" is how much you think you need, based on estimates such as your budget or past experience.

Reporting Requirements

  • Keep your request for quotations and any quotes you receive with your records for the entire retention period (6 years).

  • Quotes must be available immediately by telephone for anyone who asks.

  • Your 3-Quote Awards for the past 2 months will be made public on the Procurement & Payables website.
