Information For Vendors

Welcome to the State of Missouri’s secure, statewide eProcurement system – a one-stop-shop for procurement in Missouri.

Missouri’s web-based eProcurement system, MissouriBUYS, is powered by WebProcure, through the state’s partner, Perfect Commerce (a Proactis company). The user-friendly system provides vendor registration, electronic bid notification to registered vendors, online bidding, document submittal capabilities, electronic reminders and notifications and much more.

Vendors Need to Register

Vendor registration in MissouriBUYS was launched on August 31, 2015. All vendors who sell products and/or services to the state need to ensure their business is registered with the Office of Administration through MissouriBUYS. Registering in MissouriBUYS as soon as possible is important so you don’t miss receiving bid opportunity notifications from the State of Missouri.

Bid Locator Tool - Explore Missouri Government Bid Opportunities

Through the MissouriBUYS Bid Board, the State of Missouri offers its vendors a premium Bid Locator Tool featuring consolidated bid opportunities in one convenient location for all levels of government (local, state and federal) and political subdivisions in Missouri. The MissouriBUYS Bid Board HOSTS bid opportunities posted by State of Missouri agencies, and the new Bid Locator Tool LOCATES these state agency bids along with bids posted by local governments and political subdivisions in Missouri including cities, counties, school districts, universities, transportation departments and many others. 

The Bid Locator Tool search engine crawls websites throughout Missouri helping vendors find additional public sector bid opportunities without having to search multiple sites which saves time for the vendor.  Using the search fields and the available FILTERS, all public users can find and select the bid that interests them and be redirected to the governmental entity’s bid landing page for additional details.  To use the MissouriBUYS Bid Locator Tool, go to the Bid Board and click on the NEW Bid Locator Tool button.

Transition of Bid Postings

Following the rollout of vendor registration, the State of Missouri's former On-Line Bidding/Vendor Registration website has been phased out. On September 8, 2015 the Division of Purchasing began using the MissouriBUYS Bid Board 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 in July 2016, and a complete transition of all agencies will continue through 2018.

As we transition agency bid postings into MissouriBUYS, we encourage all vendors to continue monitoring existing agency bid sites to determine if there are bid postings not yet listed on MissouriBUYS. During an agency’s transition, MissouriBUYS may not contain all solicitations posted for the agency; some postings may still be on the agency’s bid site. For an updated listing of agency transitions to MissouriBUYS and where an agency’s bid postings can be found, please go here. Please note that this listing may change frequently.

Transition of Purchases by State Agencies

State agencies are purchasing products and services through MissouriBUYS. Until all state agencies have transitioned to the utilization of MissouriBUYS for all purchases, vendors may receive purchase order requests through MissouriBUYS/WebProcure (from or directly from the state agencies. When fully implemented, requisitions, purchase orders, catalogs/contracts, receipts and invoices will be initiated and processed through MissouriBUYS/WebProcure.

Updates and announcements will be posted on the MissouriBUYS website. Check back frequently for new information regarding this new and exciting procurement tool for the State of Missouri.


In response to the challenges the novel Coronavirus (COVID-19) presents, and to ensure the safety of the public, postal workers, couriers, and our employees, effective immediately, the Office of Administration, Division of Purchasing, as authorized by Executive Order #20-04, and as permitted by sections 34.040 and 34.042, RSMo, hereby restricts receipt of all bid responses to electronic submissions.

The step-by-step instructions for submitting bids can be found at: MissouriBUYS website.

The vendor is solely responsible for ensuring timely submission of their electronic solicitation response. Failure to allow adequate time prior to the solicitation end date to complete and submit a response to a solicitation, particularly in the event technical support assistance is required, places the vendor and their response at risk of not being accepted on time. 

If a vendor does not have electronic accessibility to submit an electronic bid response, the vendor must contact the bid’s buyer of record at least five (5) days prior to the due date of the bid to determine if an alternate process is available to accept the vendor’s bid. However, at this time under the current circumstances, electronic bid submission is the only certain way to be able to submit your bid response.
