How do I bill my users for CDN Bandwidth?
If you have integrated the control panel with HostBill, WHMCS, UberSmith, etc, you may charge your users by setting up the bandwidth price in the billing plan.
Navigate to 'Billing Plan', click on the 'Resources' button, and scroll to 'Limits for Edge Groups'. For each CDN edge group, you can define the price per GB.
The price per GB will do the counting in CP. Just click into any CDN resource, and click "Billing Statistic" then it should show you how much you should charge the CDN resource base on the price you set in billing plan.
