When will I be charged?
Campaigns run from a prepaid balance. When you submit a campaign, you authorise a first top-up of your balance by card; while campaigns run, the balance is topped up again automatically when it runs low. The amounts are stated in the campaign form before you submit.
Your Ad Balance and every top-up and ad spend are listed under Billing & Payments, in Transactions.
If a top-up is refused by your bank, we email you about it, and the Update your card button in that email opens Billing Profile — the screen that can actually fix it. Billing Profile holds your cards and your billing address, and it explains what the refusal was: an expired card, a wrong security code, not enough funds, a check your bank wanted you to complete, and so on. Add or replace the card there and delivery picks up again.
Transactions sits beside it and is the record rather than the remedy: it shows what was attempted and what it cost, but the card is changed in Billing Profile. The dashboard shows a banner about a refused card as well, and it opens the same screen.
