Once logged in as an Organization Administrator, click on your name in the top-right corner of the page, and click on Subscription.
Click the Usage menu on the left panel.
You can check your limits, how much you have used and how much is remaining (if on a trial).
You can adjust the limits as needed to limit the maximum usage as required. Once the desired limits are set, click on Apply Limits to save them.
When your subscription hits your limits or is approaching your limits, the system will notify you with appropriate messages across the application.
