When you create a new client, you can choose to create an Active account which is billed immediately, or a Trial account for client evaluation.
Trial accounts offer a 30-day evaluation period from the date of creation. During this time, the client account is fully functional.
At the end of the 30 day trial period, the account will enter a suspended state and access to the account will be blocked.
To continue using the account, you must activate the account with a paid billing subscription.
