How do I switch from monthly billing to yearly billing?

When you first create an account and sign up for membership, it presents an option to be billed monthly or yearly (at a greater than 15% discount). To change your services after you have made this election, you can go to the Account Upgrade page. You will be presented with the option to upgrade to a yearly membership. If you have any problems please contact us at memberservices@domaintools.com and we will be happy to assist you.
