How to register as a South Dakota vendor, step by step
These are the steps as the state describes them, in plain words. The portal may word things differently, and it can change, so keep the official page open beside you.
- Read the South Dakota Vendor Manual on the Office of Procurement Management page; OPM calls it a must-read for vendors.
- Use OPM's 'Register to Bid' link to set up a vendor account in the state's eProcurement system (vendor login hosted by ESM Solutions).
- Choose NIGP three-digit commodity and service codes for what you sell.
- Have a W-9 ready and check the corporate registration requirements OPM links to.
- View and bid on Invitations for Bids, Requests for Quotes and Requests for Proposals through the vendor login or the Central Bid Exchange posting board.
- Ignore any email asking for a 'digitization compliance' payment and report it to your OPM buyer.
What to have ready before you start
Registration goes faster when the basics are in front of you. For South Dakota, gather:
- Your legal business name exactly as it appears on your tax records, and any trade name you use.
- Your federal Employer Identification Number (EIN), or a Social Security number for a sole proprietor, since the state uses it to match you for payment.
- A business address, a phone number and an email address that someone reads every day; bid notices and questions from buyers go there.
- A short list of what you sell, so you can choose the matching NIGP 3-digit commodity and service codes codes in one sitting.
- W-9 form
- Corporate registration requirements (linked from OPM's vendor information)
Does it cost anything to register in South Dakota?
No registration fee stated on the official page; OPM warns vendors that emailed demands for an 'Annual Digitization Compliance' fee are fraudulent and did not come from the state. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and South Dakota does not require you to use a paid middleman to sell to its agencies. Some separate things can cost money, such as a notary for a form, a professional license, insurance or a bid bond on construction work.
Which commodity codes does South Dakota use?
South Dakota matches vendors to bids with NIGP 3-digit commodity and service codes. NIGP codes are a commodity and services code set used by many state and local buyers. They are more detailed than NAICS for products, so pick the narrow five-digit codes that match what you sell rather than one broad class. If you also want federal work, you will need NAICS codes for SAM.gov; our free NAICS code lookup and the guide what a NAICS code is help you pick them.
Cities, counties and school districts in South Dakota
Cities, counties and school districts usually run their own purchasing and bid lists, so registering with the state does not register you with them; check each local buyer you want to sell to.
Large local governments in South Dakota include Sioux Falls. Each one usually keeps its own vendor list and posts its own bids, so register with the ones you want to sell to as well.
EasBid reads many of these local sources together with the state's, so one search shows state and local bids side by side.

Tips for your first South Dakota bid
- Read the whole solicitation before you price anything; the due date, the question deadline and the submission method are usually on the first pages. Our guide on reading a solicitation shows what to look for.
- Ask questions in writing before the question deadline. Answers are usually posted as an addendum that every bidder can see.
- Check whether the bid needs a license, insurance certificate or bond, and get those started early.
- Submit through the channel the notice names, State eProcurement system hosted by ESM Solutions or otherwise, and leave a day of margin; late bids are normally rejected.
- Whether you win or lose, ask for the award results. They show the winning prices and help you price the next one.
