The Account Owner should not be someone involved in day-to-day coordination of trips, as each person can only hold one role. It should be someone senior enough to sign up to the platform and maintain user privileges. If your Centre is the first or only one registered under an Account, the clinic manager could sign up as the Account Owner. This is a normal scenario for a free trial and enables a centre to start running trips rapidly. However, as soon as possible, the Account Owner should be changed to a signatory who can authorise purchase orders and payments, as once the free trips expire, the Account Owner will need to decide which Registered Clinics it wishes to subscribe.
