With Parkster Complete, the option to create a Family Account is included. One member of the family creates the Family Account and then invites up to 3 family members (4 including himself).

How do I create a Family account?
Family account is created via the App under More and then Family account. Name the family and create an account. 

Only the family administrator - the person responsible for the payments, can invite members to the family account. The invitation is sent via SMS or email and is sent by the administrator via the app or My pages. Through a link in the invitation, the person receives information about the family account and can then link an existing Parkster account to it. If you don't have a Parkster account, you create one there and then. If you do not want to join a family account, you simply ignore the invitation.

An invitation that has not yet been responded to will appear as 'Waiting for Response' to the administrator. If the administrator wants to withdraw an invitation, this is done via the app or My pages. The invitee then receives an error message when trying to join the family. The administrator is informed via e-mail when a member has accepted the invitation to the Family Account. 

Via the App
The administrator adds family members by going to More then Family Account. Then click on 'Add family member' and invite a member via email or phone number. The family member then receives an invitation via email or SMS.

Via My pages
The administrator logs in as family admin and then goes to 'Family members'. There, choose whether the invitation to the family member should be sent via e-mail or phone number.
