Purchasing FAQs

How do I become a registered vendor?
Registration is through the Michigan Inter-governmental Trade Network System. The Michigan Inter-governmental Trade Network (MITN) is a group of agencies that joined forces to create a Regional Bid Notification System to notify companies of new bid opportunities. To register go to their website at www.mitn.info.

I had registered with St Clair County before they joined MITN. Do I need to re-register with MITN?
Yes, vendors and bidders received letters from St Clair County notifying them of the conversion.

Who should I contact for assistance with my vendor registration?
If you need assistance when registering, please click the Support tab at the top of the page within the MITN website www.mitn.info.

Monday through Friday, 8:00 a.m. to 4:30 p.m., Except Legal Holidays. Visit Purchasing on the Upper Level of the Administration Building, 200 Grand River Avenue, Suite 203, Port Huron, MI 48060

Call 810-989-6375 to arrange a meeting with a buyer. Meetings are encouraged, but are not a requirement of participation or being awarded County bids. It is generally a good idea to make yourself and the business you represent known to the buyer.

What is a Request for Proposal (RFP)?
A Request for Proposal (RFP) is typically a more complex Invitation to Bid that contains more general specifications designed to outline the minimum County requirements. Bidders must submit proposals in accordance with the requirements of the RFP.

What is a Request for Information (RFI)?
A Request for Information (RFI) is used when the County seeks help in securing information only. It may be used to determine if a vendor can provide the desired level and type of services in a cost-effective manner.

What is a Request for Quote (RFQ)?
A Request for Quote (RFQ) is typically an informal Invitation to Bid that contains make, model and manufacture part numbers for specified items and is designed to outline County requirements. Bidders must submit proposals in accordance with the requirements of the RFQ.

Who do I contact if I have a general purchasing question?
For general purchasing questions call 810-989-6375 or email Purchasing. Your call or email will be directed to the appropriate Purchasing Division staff member.
