You choose the form of payment which best adapts to your needs: bank transfer (which means we will also require an account number to which we will automatically charge any future renewal invoices) or credit card (which will also be used for renewals). Remember that you can change from one form of payment to another in your Client Area whenever you like.
Domain Protection is billed annually alongside the domain with which it is associated. If you buy this for a domain which you have bought previously, an initial prorated invoice will be issued for the months remaining until the renewal of the domain and then it will be renewed along with it.
