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 log into your google ads account and click the FIX IT button and follow the instructions.

If you do not see the above-mentioned button then follow the steps below: 

1. Go to "Tools & Settings" and click on "Billing settings". 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.
2. 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.
