Google Ads Billing & Invoices

Google charges the card/account every 30 days or whenever the account reaches €500 including VAT.

Charges are therefore not tied to a specific calendar month but rather the spend over the 30 days prior to the charge (if below €500), or the spend for whatever time period needed to accrue €500 in spend.
