When there's a large customer base, your clients might want to keep track of all the tickets raised from their company. There will be managers or employees at the VP level, who will want to get a list of tickets raised from their company. This is possible with a feature called 'Allow this contact to view all tickets from this company' which can be enabled on the contact details page.

Please click on the 'Edit' option against the contact that has to have this option enabled and click on the ticket icon next to the company field. Enabling this would allow the contact to view all tickets from that company.
