If you add to the balance of Google Ads for the first time:
Create a Google Ads account.
Fill in the following fields:
timezone (it is set automatically depending on the chosen country);
currency (choose "US dollar").
Click Save and Continue. If you entered your email address (email@example.com) when registering your account, you will immediately be taken to your new account. If you indicated the address of another mail service, you will be taken to a page where you will need to fill out some more personal data, read the terms of the service and accept them. After that, you will then be taken to your new account.
At the "Payment" stage, fill out billing information: specify the country, time zone and enter the promotional code, if you have one.
Determine the type of payment:
Automatic payments. Costs are automatically charged after advertising.
Manual payments. This payment type requires that you make payments before your ads show.
Choose the method of payment and fill in the details of the bank card.
Congratulations, you are now an official PPC advertiser!
If you already have an account with Google Ads:
Sign in to your Ads account.
In the top right corner, click the gear icon or the tool icon.
Under "Setup," click Billing & payments.
You can make a payment from any of the payment methods already associated with your account, or you can add a new payment method.
