Why is Meta charging me different amounts?

Meta bills continuously for ads that have already been shown. So a payment doesn't have to match your daily budget or come every day.

With a new account, Meta builds up trust. At first it charges small amounts, tens to hundreds of CZK. With each successful payment it raises the threshold and charges whenever the threshold is reached, or at the latest on your monthly billing date. Your total spend still matches your daily budget; only the payment rhythm changes.

You'll find an overview in Meta under Billing & payments; in Snaprime, the link is under Profile ("Profil") → Meta Billing. Check the selected ad account and the individual transactions. You can download invoices there too; they're issued by Meta Platforms Ireland.

If a payment is marked as failed, that's a different issue from normal billing. Check your payment method and any bank verification. More payment requests don't by themselves mean your budget was exceeded.
