The City of Sioux City Purchasing office's function is to purchase goods and services in a fair, competitive and cost-effective manner.

If you would like to be included as a vendor in the City's Purchasing System you will need to submit an IRS Form W-9, a listing of goods and services that your company provides, contact name, company phone number and email address. You can mail or email the information to the department.

The City of Sioux City requires a service provider agreement when work is performed on City property and vendors must comply with general conditions; If the service provider agreement is greater than $25,000 then the long form service provider agreement is used along with long form general conditions. If the service provider agreement is $25,000 or less then the short form service provider agreement along with short form general conditions are used. A bidder status form is also required when services are being performed on City property.

Proposals to bid are mailed or emailed to vendors and may be returned via mail or email depending on the bid's requirements.  Bid tabs are available by contacting our office. All information may be requested from svlahoulis@sioux-city.org
