We've made an update to our account page due to a recent Tennessee ruling. We are now required to collect sales tax for all clients operating in Tennessee at a rate of 9.25%. This change requires you to enter your billing address the next time you make a billing change to your account (e.g. change plans or a credit card). You can read more about that ruling here.
