LivePlan's payment system will accept all major debit/credit cards, such as Visa, Mastercard, or American Express. You can use any credit or debit card as long as it has a Visa or MasterCard logo and your bank allows purchases of subscription services.
If you do not want to use a card, however, you can use either PayPal or Amazon Cash.
PayPal allows you to make online payments from your bank account. You can link your bank account to your PayPal account by creating a PayPal account here. Since LivePlan is an ongoing subscription, your bank will need to authorize that type of purchase for your account.
