Yes, by logging into your client side panel on this site you can go to your account, and click the "Add Funds" button. Each billing cycle, depending on how much you put in, the system will take money from that instead of charging your credit card each month. THis is what we call our "Smart Credit Management"
If you are using the Paypal Option then Smart Credit Management will not work properly. We cannot stop Paypal from sending us payments so make sure you manage your PayPal account also.
