Facebook will charge you directly through the payment method entered within the Cobiro setup process. Each time you hit a certain payment threshold, set by Facebook which can vary from time to by and decided by Facebook, you will be charged.
If the Link Ads balance is less than the threshold then you will be charged by Facebook on your monthly bill date.
To check when billing will happen next:
- Go to payment settings in Ads Manager.
- Select in the Next bill section.
