a) In consultation with the PPB and State agencies, the CPO may operate a vendor portal, use another CPO's vendor portal, or jointly operate a vendor portal with other Chief Procurement Officers if a single portal better serves the needs of State agencies and the vendor community. A vendor portal shall allow prospective vendors to:

1. 1) Provide certifications, disclosures, registrations and other documentation needed to do business with the State in advance of a particular procurement;
2. 2) Submit the vendor's registration number, with a confirmation that the portal information is current, as part of the vendor's response to a competitive selection or a contracting process.
