In Vendors it is possible to add a note to a supplier (Vendors > Vendors > Details > Notes, complaints). You can also assign a type to these notes, such as 'Conversation note' or 'Customer visit'.
On this admin page you create and manage these note types. Existing note types are shown in the overview.

The note types that you have set here are then available as a note type when you add a note to a supplier.
