You can enable the Auto Renewal feature from the Account Panel Dashboard > Auto Clear Balance via PayPal > Enable. You will be taken to PayPal's website to complete the activation process.

Once this is done, you can activate the Auto Renewal option for each hosting service via its management page accessible via the Account Panel. For example, to enable automatic renewals for a hosting account, go to Hosting Accounts > click on the account username > Account Details > Auto Renewal option. The system will create an automatic payment for the renewal where you will be able to check the payment details at any time.
