Disk Space and Bandwidth Overage Billing
From WHMCS Documentation
- Overage billing allows you to bill based on the disk and/or bandwidth used for a given month over and above the base amount allowed with a package
- Products can still have a base price or the price and soft limits can be set at zero to bill solely based on the usage
- Usage charges are calculated on the last day of each month
- They can be invoiced on the last day of the month independantly from the related product or added as billable items to be included on the next invoice the client gets sent
- Native support is included for cPanel, Plesk & DirectAdmin modules using the values returned from the respective control panel API's but this feature can also be used by developers with their own control panels passing usage data direct to the WHMCS database
How to Configure
- The configuration of overage billing is done on a per product basis on the Other tab of product config.
- To enable it for a product, begin by ticking the Overages Billing checkbox
- Next enter the Soft Disk Limit and Soft Bandwidth Limit which should be the amounts included with the package - anything over this amount is what's considered the over usage - can be zero to bill solely based on use
- Then enter the cost per MB for disk space and bandwidth in the Disk Overages Cost and Bandwidth Overages Cost fields - these can be set up to 4 decimal places and will be multipled by the overused amount
- Click save to complete the changes
