You can change your server's billing cycle yourself in the client area: monthly, semi-annual or annual. Longer billing cycles cost less per month.
Before you start: pay any unpaid invoice. The billing cycle can't be changed while an invoice is open.
How to change your billing cycle
Step 1: Open your server's page.
Go to My servers and click Manage next to the server.
Step 2: Click Change Billing Cycle.
The button is on the server's page, above Service Actions.
Step 3: Choose the new cycle.
Choose it in Billing Cycle. The dialog shows the New Next Due Date, which is the date your server renews under the new cycle.
Step 4: Confirm.
Check the New Next Due Date and click Confirm.
Billing Overview on the server's page then shows the new cycle.
