I. Entering Billing Information for the First Time

Your account won't be activated and your ads won't run until you submit valid billing information. (If you are prepaying for your AdWords advertising, your ads will run after we receive your first payment.)

If you're ready, you can set up your billing information now.

Or, follow these steps at any time:

1. Sign in to your AdWords account at https://adwords.google.com.
2. Click the My Account tab.
3. Click Billing Preferences.
4. Complete the account setup process.
5. Click Save and Activate.

Note: Once your account is activated and your billing information has been processed, any new ads and campaigns you create can begin running immediately on Google. You will not be asked to submit your billing information every time you create a new ad or campaign.

II. Updating Billing Information

To update your billing information:

1. Sign in to your AdWords account at https://adwords.google.com.
2. Click the My Account tab.
3. Click Billing Preferences.
4. Click edit in the Primary Payment Details section.
5. Enter your updated billing information.
6. Click Save Changes when you're finished.

If your payment has been declined and you'd like to resubmit the same credit card information, you may also do so by clicking the Retry card button on your Billing Preferences page. After updating your credit card information (regardless of whether or not you use a different card), it can take up to 24 hours before your ads start running again.

You also have the option of providing a backup credit card to help ensure that your ads run continuously in the case that your primary payment method fails.
