If your Google Ads account is set up for automatic payments, a charge will be initiated by Google whenever your expenditure hits a predetermined threshold. This charge is designed to settle the outstanding balance and ensure uninterrupted ad campaigns. In cases where the spending does not reach the specified threshold, the outstanding balance will be charged at the end of the billing cycle (month).
Example: The preset automatic payment was set at $200, and with an expenditure of $500, you will incur two payments of $200 each, while the remaining $100 will be charged at the conclusion of the month or end of the cycle.
