Auto-Renewal feature saves your time and ensures continual usage of your services without downtime.
In Time4VPS, automatic payment methods are credit card and PayPal billing Agreements.
To enable one of these payment methods, you need to make the payment manually by choosing a credit card or PayPal Billing Agreement method.
So the next time the renewal invoice is generated the next day, your invoice should be paid automatically.
Note: To charge your card automatically, the card should be saved in your account.
To disable the payment method, you can do that by following this guide.
