To add another user, you may need to purchase additional user licenses.
First determine how many users licenses are available within your product plan by navigating to the Settings icon on the far right-hand corner of your navigation bar, and select "Company account."
Within the Subscription tab, you will see how many user licenses are being used out of the total available licenses (e.g. 2/10 means you can add 8 more users).
If you have exhausted all available licenses and need to upgrade your product plan, contact a sales team member via email@example.com.
If you still have available licenses, you can easily add a new user by navigating to "Resources" → "People," selecting "Add People," and assigning this new employee a username or password by checking the "Can login" option.
To add another user, you will need to purchase another licence. To do so, go to "Company account"->"Manage plan" and adjust number of users. To know how to add employee afterwards, check the video HERE.
