Don't lose access to Google Apps
Set up your billing information today so you can keep using Google Apps after your 30-day free trial is over. Remember, after entering your billing information, your paid plan doesn't start until the end of your 30-day free trial period (as long as you don't create more than ten user accounts). If you cancel your account before your trial ends, you won't incur any charges.
Just sign in to set up billing, and choose from two payment plans:
Annual plan: To receive a discounted rate, commit to a one-year contract, pay monthly for users committed upfront and add users and pay on a prorated basis.
Flexible plan: No contracts or long-term commitments. Pay only for the number of users you have each month, and add or remove users as needed.
