What Type of Procurement Do I Need?

Direct Buys

Within a calendar year, you may buy less than $10,000 of similar goods & services without a contract or comparing quotes (includes tax and freight).

You may use your discretion to support SCS-certified small businesses, even if it's not the lowest price available.

Always pay with a P-Card, if possible.



3-Quote buys ($10,000 - $50,000) are used when you know exactly what you want and will award based on the lowest price.

You must request quotes from at least three (3) suppliers registered with King County. Try to get one quote from a certified small business.
