Additional users can be added to your large account at any time during your subscription period. Additional user accounts can be purchased in the Manage Account page of your administrator dashboard by clicking ‘Purchase Accounts.’
No fewer than ten new user accounts can be purchased in a transaction. If less than half way into your current subscription period, the full yearly subscription fee per user will apply. If more than half way into your current subscription, the subscription fee per account will be halved. All additional user accounts purchased at any stage during the current subscription period expire at the end of that period.
The opportunity to add additional user accounts is also given at the time of your subscription renewal.
