AB2 1.png
2. In the downloaded file you will find two packages that support different PHP versions.
As presented on the screen below, the first one is dedicated to PHP 7, while the second one is aimed at PHP 5.4 up to PHP 5.6.
It does not apply to open source versions.

Note: You can check current PHP version in your WHMCS. To do so proceed to 'Utilities' → 'System' → 'PHP Info'.

AB2 2.png
3. Extract the downloaded file and choose the one with the right PHP version. Upload and extract the PHP file into the main WHMCS directory.

The content of PHP version files should look like this.

AB 3.png
4. Now you have to activate the module in your WHMCS system.

Log in to your WHMCS admin area. Click 'Setup' then choose 'Addon Modules'.
Afterwards find 'Advanced Billing' and press 'Activate' button.

AB 5.png
5. In the next step you need to configure your module, to do so, press 'Configure' button.

Select database driver for usage records:

  • WHMCS Database
  • External MongoDB Database

In case you choose MongoDB you will also have to provide:

  • Hostname
  • Database Name
  • Username
  • Password

Choose desired admin roles groups to grant access to the module and 'Save Changes'.

AB 6.png
6. Now, proceed to Extensions section to find more about configuring license.
7. The last step is setting up a cron job, you can find it in your WHMCS → 'Addons' 'Advanced Billing' 'Configuration' page.
AB 7.png
Well done, you have just successfully installed Advanced Billing For WHMCS!
If you have used previous version of Advanced Billing For WHMCS and you want to migrate data to the current one,

please see section How To Update section and follow the instruction there.

Configuration and Management

Now let's learn more about module's functionalities. We will present you the possibilities of our product on cPanel Extended For WHMCS example.

Please note that billing features are different in each module but the core functionality of Advanced Billing is the same for each.
Firstly, choose your module from 'Enable Advanced Billing For' dropdown menu as it is shown on the following screen.
For presentation purposes we have chosen 'cPanel Premium' with cPanel Extended module.

AB 8.png


Our module core has been designed in a way to allow collecting the records and invoices' management.

Any extra features are handled by extensions, which can be easily enabled/disabled, and are always configured per product.

Product List

On the products list, there are all the products with Advanced Billing enabled.

If the product's submodule is not supported, 'default' mode will be used instead, which enables you to bill your client for hourly usage of the product only.
Except listed products with their submodules you will find there options to:

  • control the status of your product billing, enable/disable Advanced Billing for a product
  • manage cron frequency
  • use action buttons:
    • Pricing
    • Settings
    • View Items
AB 9.png


Under Settings button there are visible Module Settings only for cPanel/cPanel Extended modules and other extensions if enabled. We will discuss them later on.
AB 10 1.png
Here you can set Application Manager (Softaculous/Installatron) and cPanel theme.

Simply enter a theme name as shown on the screen below.

AB 10.png

Used Resource Pricing

When you move to 'Pricing' section, you can set up billing for specific server resource usage like bandwidth.
AB 11.png
Manage each usage record by setting up its:
  • Free Limit - is used to set the amount of usage records for which a customer will not be charged.

In our example, a customer will not be charged for 1GB (1024MB) bandwidth.

  • Price - defines how much your client will have to pay for specific resource. Note that we provide two types of charging: units per hour and units used since the last cron run.

For example, user pays for subdomain quantity each hour, but when traffic is generated, bandwidth used since the last cron run will have to be paid once only.

  • Display Unit - category defines the manner record usage will be displayed in. It does not affect free limit and pricing, they are calculated in basic unit.

If you select 'GB' , free limit will be still 1024 MB, and price will be MB/hr, not GB/hr.

  • Status - allows you to enable/disable billing for this resource.

To proceed, choose your usage records, units, status, set up the prices and free limits. Afterwards, press 'Save'.

AB 11 1.png
As you could notice, there is also 'Configure' column.

It allows you to set up different free limits and pricing depending on resource origin.
Currently, only 'Viruozzo' and 'Openstack VPS' submodules support this feature.


To view counted usage, go to 'Items' tab.

Each cron run will create an item for each customer, if it does not exist at the moment, and add new records to existing ones.
In that way you can see current server resources usage from the last billing period.
Automatic generation of invoices is based precisely on previously created items.
To view more details click on 'View Details' as shown on the following screen.
You can also easily remove billing for specific hosting. To do so, press 'Delete Records' in 'Actions' column.

AB 13.png
In details, you can learn some detailed information on Bandwidth, Storage, Domains and other enabled records.

See the price and usage, last cron run date and total records summary.
Press 'Delete' button to remove entries.

AB 14.png


Under 'Invoices' section you can manage any of your awaiting invoices. They can be generated automatically and manually.

On the screen below you can see a previously generated invoice for our cPanel Extended account.
To view detailed information about particular invoice press 'Show Details' button.

AB 17.png
This is the place where you can verify and modify awaiting invoices. It's advised to check whether invoices are correct to avoid any risk.
AB 18.png
Let's generate an invoice for your customer manually now.

For this purpose simply click on 'Generate' next to a chosen invoice.

AB 18 1.png
After changing product's package, invoice is automatically generated for an old package.


Under 'Settings' tab you can find pages such as 'Logs', 'Integration' and 'Extensions'.
