How to register as a Missouri 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.
- Review the state's MOVERS registration instructions and checklist before starting.
- Register in the new MissouriBUYS, powered by MOVERS self-service supplier portal; registrations in the old MissouriBUYS (WebProcure) system did not carry over.
- Complete your supplier profile so you receive automatic email notices of new bids; only MOVERS registrations get them.
- Respond to new solicitations inside MissouriBUYS/MOVERS, which you must be registered in to bid.
- If you are a minority-, woman-, service-disabled-veteran- or veteran-owned business, apply for certification with the Office of Equal Opportunity.
What to have ready before you start
Registration goes faster when the basics are in front of you. For Missouri, 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 Not stated on the registration page codes in one sitting.
The pages we read did not list any extra state tax certificate or form for registration itself; individual bids can still ask for insurance, licenses or a bond.
Does it cost anything to register in Missouri?
No fee is stated on the official pages we read: No fee stated on the official page. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and Missouri 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 Missouri use?
Missouri matches vendors to bids with Not stated on the registration page; the state's certified-firm directory searches by UNSPSC codes. UNSPSC is the United Nations Standard Products and Services Code, a four-level product code set. Choose the most specific codes that match your goods or services; buyers send bid notices by these codes. 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.
Certification programs in Missouri
Certification is separate from registration. You can register and bid without it, but a certificate can open set-aside contracts or count toward goals that agencies and prime contractors have to meet. The programs the state points to:
- MBE/WBE, Service-Disabled Veteran and Veteran business certification, Office of Equal Opportunity (OEO) (oeo.mo.gov)
MBE/WBE. Minority- and women-owned business certifications show that a firm is at least 51% owned and controlled by people in those groups. State agencies use them to count toward participation goals, and some cities and counties accept the state's certificate in place of their own.
Veteran. Veteran-owned and service-disabled veteran-owned programs give certified firms access to goals or set-asides on state contracts. Federal veteran set-asides use a separate certification from the U.S. Small Business Administration.
Federal programs such as 8(a), HUBZone, women-owned (WOSB) and service-disabled veteran-owned (SDVOSB) are certified by the U.S. Small Business Administration, not by the state; see small business set-asides explained.
Cities, counties and school districts in Missouri
Cities, counties and school districts usually run their own purchasing and bid lists, so registering with the state does not put you on every local list.
Large local governments in Missouri include Kansas City, St. Louis. 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.

Our step-by-step guide to registering in SAM.gov walks through it, and federal bids on EasBid lists open notices.
Tips for your first Missouri 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, MissouriBUYS, powered by MOVERS 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.
