MissouriBUYS is a secure, user-friendly, web-based statewide eProcurement system which serves as a one-stop shop for procurements by state government agencies and includes supplier (vendor) self-service registration and profile updates, solicitations (both formal and informal), consolidated public Bid Board and Contract Board, online bidding for vendor responses, and order management (requisitions, purchase orders, contracts, catalogs, receipts.)

As of May 2024, the state began its transition to MissouriBUYS, powered by MOVERS, opening a new Self-Service Supplier Registration Portal. Until summer 2025 when transition to MissouriBUYS, powered by MOVERS should be complete, all State of Missouri Suppliers will need to be registered in both the current MissouriBUYS and the new MissouriBUYS, powered by MOVERS.
