How can I update my Zendesk subscription to change plans, change billing frequency, add products, or add and remove agents?
Only the account owner has access to manage the subscription settings. For detailed instructions on updating your plan subscriptions, see the section: Changing plan subscriptions.
Note: You can only downgrade a plan upon renewal.
If you are currently in the middle of a billing cycle, you may schedule a decrease in your agent count or downgrade your plan type to take effect on your next renewal date. However, the system only renders these changes after the renewal date. For more information, see the article: Why did my subscription change not go into effect immediately?
