All payments and invoices to purchases to Nelio Content Premium are effected and managed by FastSpring (the secure payment platform we use to manage purchases and renewals of our products). To change your payment details, look for the purchase confirmation and receipt email you received when you made your purchase. Once you have it, click on the link Manage Your Orders.
For security reason, you’ll first be requested to enter the email address with which you subscribed to Nelio Content. Enter it and you’ll have access to your FastSpring account.
From the Account Details and Payment Methods tab, you can add a new payment method (Add Payment Method) by entering the required information to change it. FastSpring will automatically use the new payment method at the next renewal.
