How can I convert my account from the free trial to a paid package?

After logging in to your account, the Choose your plan button will be displayed at the top of the screen. Click it, choose the service package (monthly or annual; Live or Automated) and provide all the necessary billing details, such as address, city or credit card number. Then, click the Buy Now button on the right side of the screen. All details regarding payments update automatically when choosing between different plans.
