Montgomery County's vision is to be the governmental leader in progressive and inclusive procurement strategies and in providing opportunities for all businesses, including small, emerging, minority, and women owned businesses that enhance our local economy.

We hope that you will partner with us in this effort. Our new Supplier Services site will allow you to update the information we have on file for your organization to ensure that we have the most current information. In the near future, it will provide our suppliers with timely electronic notification of quote and bid opportunities. It will also allow our suppliers to check the status of payments, inquire on current bid and quote opportunities, and research previous bids and quotes.
