Primary Vendor
The vendor must be recorded in IT Asset Management before being used in this field (if not, navigate to the All Vendors page: Procurement > Purchases & Vendors > All Vendors and click Create a Vendor). This is the main signatory to your contract (other than your own enterprise). Additional partners and third-parties involved in the contract can be added on the Vendors tab.
Use the search facility to select the appropriate signatory to the contract.
