Registering a new FastBill account, you will receive a welcome e-mail with a button to activate your account. Pressing this button, you confirm your e-mail adress and activate your account.
Now, your trial period starts. When the trial period ends, you can decide a FastBill rate.
Note: The first payment will take place after the end of the trial period. You can already activate a rate after 7 days of trial and use FastBill for 23 more days for free.
