Your Circa subscription is based on the number of Team Members allotted for your account.
Additional team members can be added to your account in increments of 50. To see details about your current subscription and a tally of active users navigate the the Workspace menu in the Icon Tray and select 'Billing' from the sidebar. 

In the event that you would like to add more team members you will need to reach out to our support team using the Contact Us button.

If additional Team Members are added to your subscription we will prorate the cost of additions for the remaining months of your subscription.
