Your credit or debit card is automatically charged for every $250 of ad spend, we call this amount your threshold.
But if you don't hit this threshold by the last day of the month, you will be charged your current balance instead.
You will receive an email receipt every time your card is charged.
As you start making succesful payments you can adjust your billing threshold from the default $250 limit. Click here to learn more about adjusting your billing threshold.
