Look at Wialon's documentation for Service Hierarchy> https://help.wialon.com/help/wialon-hos … -structure
Create a structure where you can have your customers under an account, and anything that has to do with testing purposes (in this case demo account) under a completely different account.
What I have done is created an account called Sandbox, then created users below for training / demo / development purposes without affecting my customers. Just load a tracker to any of the users under the Sandbox account and anything your mess up, you can completely delete everything and start from scratch without affecting any of your customers.
....Hope this helps.
