You cannot delete a user in Gazelle, but you can inactivate their user account so they can't log-in anymore.

Step 1: Go to Settings > Team Members

Step 2: Change their status to "Inactive"

Step 3: Save

NOTE: An inactive user will no longer be able to access your system. This applies system wide in both mobile app and the web app.

This setting can only be changed by logging into the Web App at this time.
