To simplify the billing process for you, we offer yearly and monthly subscriptions, which are billed automatically on a yearly or monthly basis depending on the subscription that you have chosen.
The automatic payment that was taken is most likely for the renewal of one of your subscriptions, such as your Premium Plan, domain, Google Apps mailbox or app upgrade.
You can see exactly what the payment was for by checking your invoices. To learn how to view your invoices, click here.
