Advanced Billing For WHMCS will allow you to dynamically bill your clients for the actual usage of such server resources as disk space, bandwidth or CPU. The module will also automatically generate and deliver invoices to customers in a preferred manner. As a result, not only will your clients pay only for the resources they have consumed, you will charge them whenever and however you wish!
Equipped with multi-currency support, the module provides a variety of billing variants, including hourly and ticket billing, resource usage billing, credit billing, fixed pricing or even entirely modifiable recurring billing. You will be able to adjust all basic invoicing properties, as well as define supplemental features, such as the minimum charge for invoices to be generated. At the same time, your customers will be allowed to create multiple email reminders about reaching or exceeding the specified limits of resources. Additionally, both you and your clientele will be welcome to view and customize dynamic graphs showing the consumption of resources for each service.
