1. 01

   Register on ESM Solutions bidder registration (Register to Bid)

   Start registration. Cost: Free. Register online with ESM Solutions and pick NIGP 3-digit commodity codes; notices are sent only for the codes you choose. Have a W-9 ready. ESM sells optional paid services, but none are needed to register or bid.^[2]

2. 02

   Have your South Dakota Secretary of State registration

   Vendors must register with the Secretary of State before any contract can be awarded, or state the exemption they claim in their bid.^[2]

3. 03

   Have your SB 189 Vendor Certification Form

   ^[1]

4. 04

   Choose your commodity codes

   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.

5. 05

   Watch the other buyers

   Cities, counties and authorities in South Dakota post separately. BidRover reads 2 South Dakota 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 over $50,000 use formal sealed Invitations for Bid; smaller buys use informal Requests for Quotation.^[2]

• Quotes under $50,000 do not have to go to every registered bidder, so contact agency buyers directly too.
• The state is not responsible if you miss a notice because you picked the wrong commodity codes.
