Hi, you may use any payment method you choose but we highly recommend that you use your personal account because if the account gets flagged by whatever payment option you choose and blocked, you would no longer be able to use that payment method with Ezoic again. You can add or change your payment method anytime, use this article as a guide:

Hope this helps!
