Each chief procurement officer may, in consultation with the agencies under his or her jurisdiction and the Procurement Policy Board, establish a vendor portal. The vendor portal shall allow a potential vendor to provide certifications, disclosures, registrations, and other documentation needed to do business with a State agency in advance of any particular procurement. A potential vendor who registers with the vendor portal and provides this information may submit its registration number, with a confirmation that the portal information remains current, as part of its response to a competitive selection or a contracting process, rather than submit the same information in full. One or more chief procurement officers may jointly operate a vendor portal if a single portal would better serve the needs of the State agencies and the vendor community. A chief procurement officer may accept, for use on procurements and contracts under his or her jurisdiction, the registration from another chief procurement officer's vendor portal. This Section applies notwithstanding any laws to the contrary except for later enacted laws that specifically refer to this Section.
Nothing in this Section shall preclude a State agency from implementing its own pre-qualification, certification, disclosure, and registration requirements necessary to conduct and manage its program operation.
This Section does not apply to any contract for any project as to which federal funds are available for expenditure when its provisions may be in conflict with federal law or federal regulation.
