MissouriBUYS is a secure, web-based statewide eProcurement system implemented by the State of Missouri with its partner, Perfect Commerce (a PROACTIS Company), using their WebProcure application. MissouriBUYS includes vendor (self-service) registration and profile updates, solicitations (both formal and informal), consolidated public Bid Board and public Contract Board, online bidding for vendor responses, order management (requisitions, purchase orders, contracts, catalogs, receipts, and invoices), and the MissouriBUYS Bid Locator Tool (search tool to locate bids posted by governmental entities in Missouri). 

MissouriBUYS is a user-friendly, one-stop shop for procurements (from request to invoice) by state government agencies.  MissouriBUYS includes online supplier catalogs (from awarded contracts) that state agencies can use to place orders for products and services electronically in a retail-like shopping experience (place items in a cart, checkout).  When fully implemented, state universities, local governments and political subdivisions will be able to use MissouriBUYS to post their own bid opportunities on the Bid Board, send automated notifications of bid opportunities to vendors, and receive online bid responses from vendors.

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.
