About ad billing

Each time someone clicks on one of your ads, a charge is added to your balance. You get billed for the charges from App Store ads either every 30 days or when your balance across all ad campaigns exceeds $100. Your bill will be in US dollars.

To pay your bill, you can use a valid credit card from Visa, Mastercard, or American Express. You can't use a prepaid credit card. If there is a problem with charging your credit card, then your ads will be put on hold until the problem is resolved.
