In Ad Manager, you're paid when your revenue reaches the payment threshold, as long as there are no holds on your account and you're in compliance with our policies.
However, we aren't able to send you a bank transfer at the end of the month because we first have to validate your revenue for accuracy. This process takes place the first week of every month based on the previous month's revenue. We send payments a couple of weeks later, usually during the last week of the month. So if your revenue reaches the payment threshold in February, we'll send you a payment before the end of March.
If your current balance hasn't reached the payment threshold at the end of the month, we'll roll your revenue over to the following month until the payment threshold is reached. Balances include your total combined revenue for Google Ad Manager, AdMob, and AdSense.
If a publisher's account is found to be in violation of our Terms of Service or policies, we may, at any time, withhold payment (beginning from when Google initiates its investigation of potential violations), deduct revenue from the publisher's account, and/or refund advertisers for clicks received on the publisher's site or Ad Exchange for search results page. In addition, if a publisher is past due on any payment to Google in connection with the Google Ads program, we reserve the right to withhold payment until all outstanding payments have been made.
For a complete description of payment terms, please refer to the Terms and Conditions.
