The Service Desk ticketing tool can manage two types of customers.
Once internal customers are registered by Kantar support team, they will receive an email invitation with a link to log on to the Service Desk.
CUSTOMER NOTIFICATION
When the internal customer clicks the link on the email invitation, they will be asked to create their password.
CUSTOMER LOGIN
The external customers can log on to the Service Desk without any invitation from the support team.
The first time they log on to the Service Desk, they will be asked to create their password.
The service desk portal allows you to create tickets, review tickets that were already created, and to manage your Service Desk account.
The following is an example based on the audio matching support. Other product line support has a similar interface and work the same way as audio matching support.
The portal allows you to raise a request depending on your requirements.
PORTAL FEATURES
Click Incident ticket option, a new incident ticket will open where you will have to enter details related to the incident.
Once you finish, click Create, a ticket will be created.
Generally, several customers belong to a common organisation (a group, a company,....).Tickets opened by members of an organisation can be viewed only by the members of the that organisation.
Tickets can also be opened privately using Private request option located at the bottom of the ticket creation page.
The Private request option will be seen only by the logged in customers, and not by all the members of their organisation who are not logged in.
Tickets can also be shared by the customers with other service desk members based on their email adresses or their name.
List of tickets that you had created, and tickets created by the members of your organisation can be viewed on the home page. 
Each time the support team or a customer updates the ticket, the ticket status changes, and the customer (or the support team) are notified of the change by an email.
Tickets can be closed by support team or by customers.
Customer account management provides basic features like resetting password or changing language of the interface.
