You can look up any current subscriptions associated with your account in the Account tab of your Business Control Panel by clicking the Subscriptions link.
Only your most recent purchases will show in the list
The Amount column indicates the full list price of the item, regardless of any discounts you may have
The Expires column shows the date of your next invoice. In the case of one-time fees such as Quicksites and Kicksites, Service Packages and SSL Certificates, the expiry date will show 1 year from the purchase date - but this does not mean your product expires on that date or that you will be invoiced again
