It’s possible to prevent your Team from automatically renewing at the end of the 12 months. Please note however, that doing this will mean that you are unable to add additional seats to the team at a pro-rata rate during the 12 month subscription period.
Pausing your Team to prevent auto-renewal
Log in to your Team Owner account and select “Teams” from the dashboard.
Next to the team, you will see the option to "Manage" it.
Now scroll down for the option to “Manage Team subscription”.
Click on the "Manage subscription" button and then click on "Pause subscription".
Selecting this option will prevent any automatic renewal payments being taken at the end of the billing period. When renewal is successfully paused, you will instead see a "Resume subscription" option.
If you have paused your Team subscription this doesn't mean that your subscription has ended, it just means that it won't renew automatically at the end of the 12 months. You will still benefit from the remainder of the subscription and no further payments will be taken unless you choose to restart it by selecting "Resume subscription".
Cancelling your Team to prevent auto-renewal and remove payment details
If you want to remove your payment information to permanently cancel your Team subscription, you will see an option to do so beneath the "Resume subscription" option.
If you cancel your Team subscription, the benefits of your subscription will continue until the 12 month subscription period has run its course, then when your 12 months come to an end, not only will no further payments be taken, after expiry it will be necessary to take out an entirely new Team subscription if you want to renew the team in the future.
