The supplier who manages their company's profile on the list is the Vendor Admin. If they need to transfer a supplier list registration to be managed by someone else, they will need to request that the Vendor Admin is updated for the company's profile on the list.
To provide this information to a Supplier, please use this link to the same article in the VendorPanel Supplier's Help Centre: https://vendorpanelsuppliers.zendesk.com/hc/en-us/articles/900002557503-Transferring-a-Supplier-List-to-Someone-Else
Suppliers cannot transfer the list to another user themselves in their accounts. The only way they can update the Vendor Admin on the list themselves is by updating the profile and login information in the account from one person to another (if the new user does not already have their own account).
As Supplier Lists act as a contract between suppliers and the list-owning organisation, they will need to contact the List Owner (the Super Admin or Panel Administrator who owns the list) to request a change to the Vendor Admin for that list registration.
It's best practice for the new Vendor Admin to be registered as a Colleague on the list before the transfer is made. You can find steps on how the Vendor Admin can manage colleagues on a list here: Suppliers Adding and Removing Colleagues.
If the existing Vendor Admin who manages the list has left the organisation and they can no longer access their account, then they can either contact the List Owner or VendorPanel Support for assistance.
If they are registered on the supplier list as the Vendor Admin or as a Colleague then they can find the List Owner’s contact details by selecting Lists you're on under the Supplier Lists section on the homepage on the left-side menu)
They can click on the list name (in blue) to view the list’s details and relevant contact information.
They will then need to contact the List Owner on the phone number or email provided and ask that they replace the Vendor Admin with a new user.
Any Panel Administrators can update the Vendor Admin for a company on any internal Supplier List, please see here for more information: Updating the Vendor Admin for a Supplier.
