MissouriBUYS is a new, secure web-based eProcurement system being implemented by the State of Missouri that will result in greater procurement efficiencies statewide and improved access to business opportunities by vendors and small businesses. When fully implemented, MissouriBUYS will be a user-friendly, one-stop-shop for procurements by the state.

MissouriBUYS replaced the state’s previous On-Line Bidding and Vendor Registration System with a consolidated public Bid Board and a new vendor registration system that allows the vendor to self-register and self-maintain their account. When fully implemented, MissouriBUYS will also include a virtual marketplace that will consist of online supplier catalogs which state agencies, local governments and political subdivisions will be able to use to purchase products and services electronically.

On September 8, 2015 the Division of Purchasing began using MissouriBUYS to post new bid opportunities which generates automated notifications to vendors registered in MissouriBUYS based on commodity codes entered during a vendor’s registration or profile update. Additional state agencies began transitioning their bid postings to MissouriBUYS in July 2016 and a complete transition of all agencies will occur in 2017.

The implementation of MissouriBUYS is occurring in phases beginning in August 2015 with completion of all phases occurring in 2017.

Perfect Commerce is the State of Missouri’s partner for the implementation of MissouriBUYS, the state’s new web-based statewide eProcurement system. The MissouriBUYS system utilizes Perfect Commerce’s WebProcure application.

WebProcure is Perfect Commerce’s software application that is being utilized within the secure MissouriBUYS website for vendor registration, posting and awarding solicitations and bids, sending email notifications to prospective vendors, and providing a way for users to easily view awarded contract information. When the system is fully implemented, WebProcure will also be used for processing orders and payments for products and services.

As of August 31, 2015, businesses can no longer register as a vendor or update their vendor information on the state’s former OLB website. Any bids/solicitations issued by the Division of Purchasing with a bid posting date on or after September 8, 2015 can only be found in the MissouriBUYS system.

Vendors can easily view business opportunities posted on the public Bid Board, electronically submit bids or proposals if registered as a vendor in MissouriBUYS, receive automated notifications of bid opportunities, and review award results and postings electronically. MissouriBUYS will be a one-stop-shop that will include a virtual marketplace consisting of online supplier catalogs that state agencies, universities, local governments and political subdivisions can use to purchase products and services electronically once the system is fully implemented. In addition, vendors only have to register once for multiple state agencies rather than having to contact separate state procurement offices to be added to their bidder lists. Vendors are also able to self-maintain/manage their vendor profile in MissouriBUYS.

State agencies will have the ability to advance from requisition to receipt of products more quickly and effectively. MissouriBUYS will modernize purchasing operations, streamline processing orders and payments, and enable state agencies to place orders electronically through the virtual marketplace. As state agencies transition to MissouriBUYS, their bid opportunities are being posted on the consolidated Bid Board eliminating the need to maintain a separate bid site for their agency’s procurements.

Once fully implemented, universities, local governments and political subdivisions will have the ability to post bid opportunities on the public Bid Board in MissouriBUYS and receive online bid responses from vendors registered in MissouriBUYS. The new system will also provide improved access to state bids and contracts, the ability to easily purchase products electronically through the virtual marketplace of online supplier catalogs, and an easier way to do business with vendors.

Vendor Registration

Yes, if you sell products and services to the state, you need to register in MissouriBUYS in order to receive automated notifications of new solicitations, respond electronically to solicitations posted on the Bid Board, and receive purchase orders automatically from awarded contracts when the system is fully implemented.

You may register as a vendor in MissouriBUYS now.

You must complete the online form located on the following webpage:

A Vendor Registration Checklist can be found on the MissouriBUYS website under Training.

The state is using the UNSPSC commodity/service code set in MissouriBUYS. Users can search and select applicable UNSPSC commodity/service code(s) when registering as a vendor. Missouri requires at least one UNSPSC code be selected in order to become an approved vendor in MissouriBUYS.

Registering in MissouriBUYS and selecting the appropriate UNSPSC code(s) for your business will subscribe you to receive automated email notifications of bid opportunities based on commodity code matches. Registering will also make it easier for your business to find bid opportunities.

Several step-by-step Vendor Registration Instruction Guides can be found on the MissouriBUYS registration page ( to assist you with the registration process and editing your profile once registered. If you need additional assistance with vendor registration or navigating the WebProcure system within MissouriBUYS, please email or call Perfect Commerce’s WebProcure Technical Support team at or (866) 889-8533.

The State of Missouri’s former On-Line Bidding/Vendor Registration (OLB) website was phased out and replaced by MissouriBUYS. The state’s central purchasing office (Division of Purchasing) began using MissouriBUYS on September 8, 2015 as its new bid posting and automated notification site. Vendors registered in MissouriBUYS receive automated notifications of bid opportunities based on commodity code matches, can respond electronically to bids and proposals posted in MissouriBUYS, and are able to self-maintain their vendor profile.

As of September 8, 2015, if you are not registered in MissouriBUYS, you will not receive automated bid notification(s) when bid opportunities are added to the Bid Board. As additional state agencies continue to transition to MissouriBUYS, their specific agency bids are being posted in MissouriBUYS and no longer on their agency bid site. A contract cannot be awarded to a vendor through MissouriBUYS if they are not an approved vendor in the system, and awarded contracts cannot be set up in MissouriBUYS for easy ordering by agencies if the contracted vendor is not an approved vendor in MissouriBUYS. In addition, vendors who do not register in MissouriBUYS are unable to submit electronic bid responses.

Once you provide the minimum data required to register, you can log in at any time later to provide this additional information by selecting My Account from the User Menu dropdown located by your name in the upper right hand corner. In addition, an “Instructions for Editing and Managing Your Vendor Profile” document can be found on the website. Please note, however, that you cannot become an approved vendor until your completed and signed W-9 has been uploaded and verified in MissouriBUYS.

Your information will be visible only to the State of Missouri and to any other WebProcure Buying Organization(s) you select to do business with.

If your company operates only in select locations of the State of Missouri, you can select the counties where you are available to provide products and services when you register. If you support statewide service, no action is necessary when registering (i.e. ‘statewide’ is automatically set as the default).

Click on the drop down arrow by your name at top right corner, go to My Account and expand Account Management (i.e. click on the ‘+’ sign). Expand State of Missouri (i.e. click on the ‘+’ sign), select Additional Required Attributes, and scroll down to the Select Counties Below section. Check or uncheck the appropriate counties and click Save. When initiating initial registration, vendors can select regions; however, when updating the vendor profile, counties can be selected but not regions.

You still need to register in MissouriBUYS and provide your ACH-EFT information to ensure that automated payments can continue.

Organizations with multiple branches or locations can register as a single vendor if the Corporate Office is the main office doing business with the State and the other offices are providing supporting roles like Bids/Solicitations, Purchase Orders, and Remittance for the corporate office. In this instance, you should register as a single vendor and load the other locations as the appropriate contacts within their vendor record. If, however, the 5 business locations could all have separate or separately paid contracts with the State, then each location needs to register separately as a vendor and indicate they are a ‘branch’ for the organization. In this case, each location could have its own Main Contact, Bid/Solicitation Contact, Purchase Order Contact, and Remittance Contact. Vendors registering as a ‘branch’ location should enter the tax ID number for their headquarters.

If you receive a Purchase Order from the state for any products or services, you do need to register in MissouriBUYS. If you are receiving direct payments from the state that are not for products and services and instead are for program reimbursements or other grant payments, you do not have to register in MissouriBUYS. Registering in MissouriBUYS allows a company to update and self-maintain their own contact and address information (e.g. mailing, payment address, etc.) with the state when needed instead of submitting paper forms.

If you do not wish to receive notifications of bid opportunities, you should select Unknown (00000000) as your UNSPSC commodity code.

You are required to select at least one commodity/service code. If you do not wish to receive notifications on solicitations, you should select commodity/service code Unknown (00000000) and you will not receive notifications on solicitations.

MissouriBUYS systematically assigns a new vendor number to each new vendor when they register. During the transition to MissouriBUYS, the state is able to cross-match the old and newly-assigned vendor number for each vendor.

Missouri is assigning new vendor numbers that will begin with ‘MB’ with the implementation of MissouriBUYS. The state will be using both numbers for a period of time. There will be a transition to the new ‘MB’ number, and the state will retire the old vendor number at a later date. Existing and new contracts will be awarded with the new ‘MB’ number as the agency awarding the contract converts to MissouriBUYS.

Once you’ve completed and submitted the registration form, the state will review your registration. Please note Missouri requires that a completed and signed W-9 form be uploaded into MissouriBUYS and at least one UNSPSC commodity code be selected in order to become an approved vendor in MissouriBUYS. When the registration review process is complete, an approved vendor will receive an email from the state confirming their approval status.
