Installation

In this tutorial we will show you how to successfully install and manage Advanced Billing For WHMCS. We will guide you step by step through the whole installation and configuration process.

1. Log in to our client area and download the module.

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 5.6 up to PHP 7.0, while the second one is aimed at PHP 7.1 up to PHP 7.2. It does not apply to open source versions. Note: You can check the current PHP version in your WHMCS. To do so, proceed to 'Utilities' → 'System' → 'PHP Info'.

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.

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.

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 If you choose MongoDB, you will additionally have to provide: Hostname Database Name Username Password Choose the desired admin roles groups to grant access to the module and 'Save Changes'.

6. Now, proceed to the Extensions section to find more about configuring the license.

7. The last step is setting up a cron job. You can find it following the path: WHMCS → 'Addons' → 'Advanced Billing' → 'Configuration' page.

Well done, you have just successfully installed your Advanced Billing For WHMCS!

If you used the previous version of Advanced Billing For WHMCS and you would like to migrate the data to the current version, please see the How To Update section and follow the instructions listed there.

Configuration and Management

Now, let us learn more about the functionalities of the module. We will show you the possibilities of our product, using cPanel Extended For WHMCS as an example. Please note that the billing features are different in both modules, but the core functionality of Advanced Billing remains the same. First, choose your module from the 'Enable Advanced Billing For' dropdown menu as shown on the screen below. For demonstration we have chosen 'cPanel Premium' with the cPanel Extended module.

Core

Our module core has been designed in such a way so as to allow the collection of 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 you can find all products which have Advanced Billing enabled. If the product's submodule is not supported, the 'default' mode will be used instead. It enables you to bill your client only for an hourly usage of the product. Apart from the products and their submodules, the Products List contains also the following options: Control the status of your product billing, enable/disable Advanced Billing for a product Manage cron frequency Use action buttons: Pricing Settings View Items

Settings

Clicking on the 'Settings' button will allow you to see the Module Settings only for cPanel/cPanel Extended modules and other enabled extensions. We will discuss them later on.

Here you can set both Application Manager (Softaculous/Installatron) and cPanel theme. Simply enter a theme name as shown on the screen below.

Used Resource Pricing

Moving to the 'Pricing' section will allow you to set up billing for a specific server resource usage like bandwidth.

Manage each usage record by setting up its: Free Limit - used to set the amount of usage records for which a customer will not be charged. In our case, as you can see on the screen below, a customer will not be charged for 1GB (1024MB) bandwidth. Price - defines how much your client will have to pay for a specific resource. Note that we provide two types of charging: units per hour and units used since the last cron run. For example, users pay for a quantity of subdomains each hour, but when the traffic is generated, bandwidth used since the last cron run will have to be paid once only. Display Unit - defines the manner in which the record usage will be displayed. It does not affect free limit and pricing - they are calculated in a basic unit. If you select the 'GB' option, free limit will be still 1024 MB, and the 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, statuses, set up the prices and free limits. Afterwards, press 'Save'.

As you probably noticed, there is also a 'Configure' column to the right. It allows you to set up different free limits and pricing depending on the resource origin. Currently, only 'Viruozzo' and 'Openstack VPS' submodules support this feature.

Items

To view the counted resource usage, go to the '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 the existing ones. In this way you can see the resource usage of the current server for the last billing period. Automatic generation of invoices is based precisely on the previously created items. To view more details, click on 'View Details' as shown on the following screen. You can also easily remove billing for a specific hosting. To do so, press 'Delete Records' in the 'Actions' column.

This section will show you some more detailed information on Bandwidth, Storage, Domains and other enabled records. See the price and usage, the last cron run date and the total records summary. Press 'Delete' button to remove entries.

Invoices

In the 'Invoices' section you can manage all of your awaiting invoices. They can be generated both automatically and manually. On the screen below you can see a previously generated invoice for our cPanel Extended account. To view more detailed information about a particular invoice, press 'Show Details' button.

Here you can verify and modify your awaiting invoices. To avoid any risks, you should double check that all your invoices have been generated correctly.

Now, let us manually generate a sample invoice for your customer. For this purpose, simply click on 'Generate' next to the chosen invoice.

After changing the product's package, the invoice will be automatically generated for an old package.

Settings

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

Integration Code

The 'Integration' page contains codes required to integrate Advanced Billing For WHMCS with your client area. The first code allows you to display product pricing while placing an order. Note: The integration code path may vary depending on the order template you are using.

If the code has been typed in correctly, the sample order should look like this:

The second integration code is responsible for displaying usage records in the client area. Note: To display usage records in the client area, you need to enable 'Usage Records' or 'Notifications' extension for the product.

If the code has been typed in correctly, the sample resource usage should display like this:

Items Archive

On this page, you can find information regarding the archived usage records. Once a client has paid for the used resources, the usage history will be automatically moved to the archive. There is a number of archived items along with the space they take up on the disk.

Use the 'Flush' option to clear the archive and remove all stored data. You can also set the time interval to indicate the number of days after which the archive will be cleaned automatically.

Logs

On the 'Logs' page you will find information about the module's activity. You can view logs in the form of a 'Database' or a 'File' . You can select it in the place marked on the screen below.

Here you will see different types of logs including informative logs, error logs and critical logs. New log files are created every day to help you always find the information you are interested in.

Extensions

In this section we will describe each extension step by step. Important: Only five of them are included in Advanced Billing For WHMCS. You can enable each one of them after moving to the 'Settings' → 'Extensions' section. You can see all five extensions on the screen below. The rest of the extensions listed there can be obtained separately. The five default extensions in Advanced Billing For WHMCS include 'Recurring Billing', 'Usage Records', 'Credit Billing', 'Graphs' and 'Notifications' . Note: Do not mistake Recurring Billing extension for Advanced Billing with Recurring Billing Extended For WHMCS module. Each extension can be configured per product, thus allowing you to use different sets of extensions according to your needs. To start using an extension, you need to first activate it. To do that, go to 'Settings' → 'Extensions' page. Afterwards, 'enable' the extension you wish to use, and new options will appear in Advanced Billing For WHMCS.

If you skip the steps 3-4 from the installation instruction, you have to configure the license for each of the 4 base extensions. Note that each of them uses Advanced Billing license key. Press 'Configure', paste your license key and confirm changes.

Credit Billing

'Credit Billing' extension allows you to charge your clients for a product from the client credit balance. To enable this option for a single product, click on 'Settings' button next to the chosen product. If the extension is enabled, a new tab will appear.

Enable Credit Billing - this option enables/disables credit billing for this module (if credit billing is enabled, standard billing will be turned off). Create Invoices Each - this option defines how often an invoice will be generated for this product (30 days is a default value). Minimum Credit - minimum amount that will be charged from the client account credit balance. Low Credit Notification - if this value is higher than credits on the client's account, an email to your client about low credit amount will be sent. Email Interval - defines how often low credit notification email will be sent, the interval refers to the number of days. Autosuspend - when credit balance reaches 0, the product ordered by the client is automatically suspended and an invoice reminding of the lacking amount will be generated. Note: This function also takes account of the ''Override Auto-Suspend' feature. Due Date - the number of days when your customers have to pay for the invoice. Credit Autorefill - if enabled, client's credit balance may be refilled from his credit card each time it became empty. Gateway - gateway used to charge client's credit card if autorefill is enabled. Minimum Amount - minimum amount to charge from client's CC. Maximum Amount - maximum amount to charge from client's CC. Note: Clients can define if they wish to use autorefill functionality as well as choose amount to refill in a single run.

When the option 'Autosuspend' is enabled and your client's credit balance reaches 0, the client's product will be suspended. Additionally, an invoice reminding of the lacking amount will be generated. If it is disabled and the credit balance reaches 0, the client's product will not be suspended and invoice will be generated according to the number of days set in the 'Create Invoices Each' field.

Credits

All information related to the credit payment for hosting can be found in the 'Credits' tab that will appear in your menu when enabled. As you can see, there are two columns with credits. The first one, 'Internal Credit' contains credits which were not used for payment, but are reserved for it. It was created to increase the accuracy of credit billing. The second column, 'Already Paid For Hosting' contains a summary of the credit payment for hosting. You can order a refund of any hosting by pressing 'Refund' button next to the hosting service. The client will receive a sum of 'Internal Credit' and 'Already Paid For Hosting' rounded down to 0.01.

Recurring Billing

This extension allows you to set up recurring billing for your product. Enable Recurring Billing - check to enable this billing type (remember that Recurring Billing and Credit Billing cannot be both enabled at the same time) Bill On Termination - when the account connected with your module is terminated, an invoice for the account will be generated. Billing Type - enables you to choose how to bill your client. Bill On Invoice Generation - customers will receive an invoice at the same time as the invoice for their hosting account. Bill On Specific Day - generates invoices each month on the day specified in the Billing Type Value. Bill Each X Days - as the very name suggests, generates an invoice each X days where X is the number specified in the Billing Type Value field. Due Date - the number of days in which your customers will have to pay the invoice. Autogenerate Invoice - if enabled, automatically sends the previously generated invoices directly to your customers. Auto Apply Credits - automatically applies any available credits when an invoice is created. Works only if the 'Autogenerate Invoice' opiton is enabled. Advanced Billing Cycle Info - if enabled the billing cycle information in client area product view will be replaced to 'Hourly Billing' . Apply Group Discount - enable if you want to apply the discount to the invoice set in the client group.

Usage Records

This extension displays usage records and usage records history in the client area products page. To use it, you need to of course first enable it, and then place an integration code. This extension can be configured per product. To do so, proceed to the product configuration in Advanced Billing. As you can see, a new tab is available. Enable - enables the display of usage records for that product in the client area. Display Summary From - defines the period from which usage records will be counted. Usage Records Precision - the number of decimal digits indicating the precision of usage records. Records History - displays history of usage records. Usage Records Per Page - defines how many usage records should be displayed per page.

On the following screen you can see a sample of usage records and usage records history in the client area.

Fixed Pricing

Use the 'Fixed Pricicng' extension to bill your customers after a specified number of hours of active service usage. Set a defined amount that will be billed per product.

First of all, enable the extension for a single product. Keep in mind that 'Fixed Pricing' cannot be enabled together with 'Credit Billing' and 'Recurring Billing' extensions. Auto Apply Credits - enable to automatically apply credits if there are any available in the client's credit balance Tax - if enabled, tax will be added to the created invoice Hours - define a number of hours that must pass before the service is billed at a monthly rate Due Date - define payment due date USD or any available currency - set the pricing amount in any currency to bill clients after a declared number of hours has passed In case the defined in 'Settings' hour treshold is not reached, the client will be billed for generated usage in a standard manner.

Graphs

Enable the 'Graphs' extension to gain access to the graphical display of usage records for every configured service in your Advanced Billing module.

When enabled, a new entry in your navigation menu appears → 'Graphs'.

Please note that before proceeding, you must also enable the 'Graphs' extension for the product. To do so, move to 'Configuration' → 'Products List' → 'Settings' → 'Graphs'. Enable the extension and save the changes.

In the 'Graphs' section you will find an extended list of all services in your system. Press 'Show Graph' button and you will be moved to the generated line chart.

You will immediately see a line chart generated for a default resource usage and time period. You may change the requirements at any time to see a customized version of the graph with data that you actually need, and the time period you desire. Use options located to the left of the graph to personalize the chart statistics.

Line charts can be displayed not only by administrators in their panel but the clients as well. Find 'Resource Usage Chart' in the product's details to preview the generated graph. Clients, just like admins in admin area may specify the time range and select resources which they wish to see in the graphical mode.

Notifications

Enable the 'Notifications' extension to allow your clients to set email reminders that will be sent when a specified resource usage limit is reached or exceeded.

Before your clients will be able to configure reminders, you have to enable the 'Notifications' extension for the product. To do so, move to 'Configuration' → 'Products List' → 'Settings' → 'Notifications'. Enable the extension and, if you wish, define a maximum nuber of notifications a client may create and change the default email template. Save the changes when ready.

You will find a list of email templates in the 'WHMCS' → 'Setup' → 'Email Templates' section. By default, the 'Advanced Billing Resource Usage Reminder' template in 'Product/Service Messages' is used. You can modify the template to your needs, or alternatively create a new one, then assign it in a previous step. Note that beside the WHMCS default 'Available Merge Fields' you can also use the following variables for the extension purposes: {$reminder_name} - the name of a reminder set by a client {$type} - the resource type for which the limit has been set by a client. E. g. 'Storage' , 'Bandwidth' etc. {$usage} - the current recorded usage value of the resource type the limit is set for {$limit} - the limit value defined by a client whose reaching or exceeding results in sending the notification {$unit} - the unit of the billed record. E.g. 'MB' , 'GB' etc.

Now, while in the client area, you can see the tab with new reminders. Press 'Show to expand it and click on the 'Add Reminder' button.

Set the name of a reminder name along with the frequency with which the module will check the usage and send notification emails once the limits are reached or exceeded. Note that in addition to selecting the default frequency option from the dropdown menu, you can enter a different numeric value that will determine the frequency in hours.

Now you can define resource limits on the basis of which notifications will be sent.

Determine if reminders shall be dispatched after a particular value is reached, exceeded or both.

If any of defined conditions is fulfilled, the reminder is sent to the client with the frequency set in the previous step. The reminder will no longer be sent if, after the resource usage check, it turns out the level of a given resource type is once again below a defined limit.

Keep in mind that you can add multiple reminders, each with different limits and different frequencies of checking resources and sending notifications. Once created, you can easily toggle the status of every notification, as well as modify its settings whenever required.
