How do I set up my billing information in Google Ads?

To add your billing information in Google Ads (formerly Google AdWords), you need to follow the steps below: 

1. Log into your Google Ads account and click on the "Tool" icon at the top right of the page. 
2. Go to "Setup" and click on "Billing and payments". There you can edit your payment details. Depending on your country, you'll see different options for payment methods and billing options. You can read more about it here.
3. After entering all required information (country, tax information and billing information), you’ll have to read the Terms & Conditions for payments in Google Ads. When you’ve accepted them and submitted your information to Google, your setup will be completed.
