How to sell to Montana government

State agencies post on eMACS (electronic Montana Acquisition and Contracting System).^[1] State building construction Invitations to Bid are posted on the Architecture & Engineering Division web page; A&E RFPs and RFQs are in eMACS under the Architecture & Engineering Division work group.

Changed recently: Old State Procurement Bureau pages (spb.mt.gov) now redirect to the State Procurement Services Division (SPSD) on doa.mt.gov.^[2]

   Register on eMACS vendor registration (Profile 1 / Profile 2)

   Notifications are sent by the codes in your vendor profile. Pick every code that describes your work, and revisit them when you add a service.

   Watch the other buyers

   Cities, counties and authorities in Montana post separately. BidRover reads 3 Montana sources, listed below, in one search.

Exact requirements vary by portal; the registration page linked above is the authority. Most ask for:

• Your legal business name and address exactly as registered with the state, and your federal tax ID (EIN, or SSN for some sole proprietors).
• A signed IRS Form W-9, which most buyers collect before they can pay you.
• Commodity codes (NIGP, UNSPSC or NAICS, depending on the portal) for every product and service you sell.
• A contact who will receive bid notices, plus any business license or registration the jurisdiction requires.
• Certificates of insurance and, for construction, bonding capacity: these are usually requested per bid rather than at registration.

Purchases under $10,000 are small purchases; purchases from $10,000 up to under $100,000 may use a limited solicitation with at least three quotes if available.^[3]

• Use the vendor portal at vendorportal.mt.gov and keep one account per company; contact the eMACS help desk before registering if you may already be listed.
