Advanced Billing For WHMCS

Overview

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!

The module comes supplied with multi-currency support and integration with nearly 20 renowned modules, including those for cPanel, Plesk, Proxmox VE and OpenStack. You will be empowered to select from an exceptional variety of advanced billing alternatives, such as hourly and resource usage billing, credit and prepaid billing, fixed pricing, or even entirely modifiable recurring billing. In addition, products together with configurable options can be automatically upgraded or downgraded following the change in resource consumption. Furthermore, you will easily 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. As a bonus benefit, both you and your clientele will be welcome to view and customize dynamic graphs showing the use of resources for each service.

Fully automated in all respects, plus freely customizable billing and invoicing in WHMCS – seems unreal? Not with our Advanced Billing For WHMCS! Start charging your clients for nothing but the resources that turned out to be needed, and let our module handle everything else!

Advanced Billing For WHMCS

LUIZ AMERICO DOS SANTOS (ATRIUM HOST) 7 months ago

Excellent module that has taken our Billing System to the next level. Advancend Billing is a must if you need to charge your customers for resources used and have exact control of each resource used with ease. We have already purchased it and recommend it. The module has been completely rewritten and continues to be fantastic.
