In the Account Settings you can manage your paid services on Issuu. You can purchase new services, cancel existing services, or change your billing interval from monthly to annual.
You can change your services at any time. If you upgrade from monthly to annual billing interval, the changes will happen immediately. If you downgrade from annual to a monthly billing interval, the change will happen immediately, but the remaining pre-paid annual period will be credited to your account and used for future invoices. This is listed as "Service Credits" and there are non-refundable.
