Your credit or debit card is automatically charged when you hit the billing threshold set for your account. All running campaigns account for an overall ad spend balance and the charge is applied across multiple campaigns. The default threshold is $250.
If you don't reach your 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.
