In Visma Severa it is possible to delete customer's contact person. Delete option can be found under More actions menu on contact card.
You need to confirm deleting as person's information will be deleted from all sales cases, projects and activities and the action cannot be undone. Note that contact person's name will still be shown on past invoices.
After a contact person is deleted you'll see text "Deleted Contact" instead of his/her name throughout the system.
