Extracted files in your WHMCS directory should look like this:

LOF 2.png
3. When you install 'Lagom One Step Order Form' for the first time, you have to rename the 'license_RENAME.php' file.

The file is located in 'modules/addons/LagomOrderForm/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'.

LOF 4.png
4. In order to configure your license key, you have to edit the previously renamed 'license.php' file.

Enter your license key between quotation marks as presented on the following screen. You can find your license key in our client area → 'My Products'.

LOF 5.png
6. Now, set up the 'storage' folder as recursively writable.

This folder is available at 'your_whmcs/modules/addons/LagomOrderForm/'.

LOF 6.png
7. Finally, set the 'htaccess' file rule

Open the 'htaccess' file, you will find it in the main root directory.

8. If you have 'fully friendly rewrite' set up, you will have to paste the below rule underneath 'RewriteBase /' :
   RewriteBase /
   RewriteRule ^order/(.*)$ order.php?m=OneStepOrder&gid=$1 [L]

Otherwise, create the below rule above the WHMCS rules:

  RewriteBase /
  RewriteRule ^order/(.*)$ order.php?m=OneStepOrder&gid=$1 [L]
*9. This step is optional:

If you are using an NGINX server, it is advised to add the below lines into its configuration file. Otherwise, the module might not work properly.

 location /order {
   rewrite ^/order/(.*)$ /order.php?m=OneStepOrder&gid=$1 break;
 location /modules/addons/LagomOrderForm/api/ {
    try_files $uri $uri/ /modules/addons/LagomOrderForm/api/index.php?$args;

Remember to adjust the above example to your WHMCS location.


9. Now, you have to activate the module in your WHMCS system.

Log in to your WHMCS admin area and proceed to 'System Settings' 'Addon Modules'.
Afterward, find 'Lagom One Step Order Form' and press the 'Activate' button.

Lagom One Step Order Form For WHMCS has been designed to give flexibility for the clients and allow to configure it to specific business needs.
Below we will describe all the available customization options.

Addon Configuration


Begin by navigating to the “Lagom One Step Order Form” addon in your WHMCS admin area, there the “Templates” section will be opened by default.
LOF 11.png

Order Form Type

In the 'Order Form Type' section you may choose which of the available order types should be used in the client area. You may choose between three types, these are:
  • One Step
  • Two Steps
  • Step by Step* (available soon)

For detailed description with visualization in the client area look below.

LOF 11 1.png
The first one, called 'One Step' allows you to decide whether to show all of the product configuration options on a single page only.

Note that at the beginning of the ordering process your client will be able to switch between different product packages within a specific product group.

Client area view:

LOF 12.png
When the 'Two Steps' option is selected, the order process is divided into two separate steps, where the first one allows you to choose a product to order.
In the second step the configuration options available for the previously selected product are displayed.

Note: It is not possible to switch between products if this order form type is selected.

Client area 'Step 1' view:

Client area 'Step 2' view:
LOF 14.png
'Step by Step' - this option is not yet available, it will be added to the module in one of its upcoming versions.

Order Form Layout

The second option to customize the template is dedicated to the location of the "Order Summary" element - 'Order Form Layout'.

There are two possibilities to choose from:

  • Sidebar
  • Bottom

Underneath you will find details of every possible choice with its visualization in the client area.

LOF 15.png
Sidebar - if selected, the 'Order Summary' box is displayed on the right side in the client area order page.
The summary box is always affixed to the top of the browser screen, so clients will also have quick access to the complete summary of the current order.
LOF 16.png
When the 'Bottom' option is selected, the 'Order Summary' box will be displayed at the end of the order process.
LOF 17.png
In case of the 'Bottom' order form layout, a quick summary bar with the total amount and the checkout button will be available at the very bottom of the screen.
LOF 18.png

Package Type

This selection of the 'Template' setting, defines the layout of the product package that will be used. You can choose between two options: 'Default' and 'Horizontal'.

Navigate to the 'Lagom One Step Order Form' addon, 'Settings' tab. There you may manage all the extra layout settings:
  • Package Slider - decide whether you would like to use a slider to view the content of a product group that contains more than three packages in the case of the 'Sidebar' order layout,
    and more than four packages in the case of the 'Bottom' order layout.
  • Simplified Summary - if enabled, the "Order Summary" box displays only 'Totals' and 'Total Due Today' values.
    It will not display any details about added products, domains or addons.
  • Display Price Suffix - if enabled, the currency suffix is shown next to the price.
    However, it is important to previously configure the currency and its suffix details in your WHMCS admin area settings, based on their video tutorial
  • Show Domain Spotlights - allows you to display "Spotlight TLDs" which have been previously configured in WHMCS settings.
  • Display Navigation Tabs - if this option is enabled, the additional navigation tabs are shown below the main header title.
  • Disable Redirection - if enabled, automatic redirection from standard WHMCS cart and order pages will be turned off. When clients use a ready link to e.g. a cart, it will be displayed with a standard WHMCS view.
  • Hide Currency Selector - toggle to hide the currency switcher that is visible on the order page if just one currency is active in the WHMCS system
  • Hide VAT Field - select countries for which the 'VAT Number' field in the account details will be hidden
  • Browser's Title Bar - if you want to change the default title tag, enter here a new phrase, it will be visible in the title bar at the top of the browser window in the client area
LOF 22 0.png
Package Slider - decide whether you would like to use a slider to view the content of a product group that contains more than three packages in the case of the 'Sidebar' order layout,
and more than four packages in the case of the 'Bottom' order layout.
LOF 22.png
Although the 'Slider' option is enabled, your clients still have the option to display all of the packages at once, without the need to scroll them horizontally.
When All option is on, all products in the package are displayed in multiple rows.
LOF 23.png
When the Simplified Summary option is enabled, the "Order Summary" box displays only 'Totals' and 'Total Due Today' values.
It will not display any details about added products, domains or addons.
LOF 24.png
When the Display Price Suffix is enabled, the currency suffix is shown next to the price.
However, it is important to previously configure the currency and its suffix details in your WHMCS admin area settings, based on their video tutorial
LOF 25.png
Show Domain Spotlights allows you to display "Spotlight TLDs" which have been previously configured in WHMCS settings.
When the Show Domain Spotlights option is disabled, no domain TLDs are displayed below the domain search bar.
LOF 26.png
When the Display Navigation Tabs option is enabled, the additional navigation tabs are shown below the main header title.
The navigation tabs include the product groups, which previously must be configured in WHMCS settings.
LOF 28.png


The 'Gateways' section is dedicated to super easy customization of your payment gateways.
You can quickly upload new gateway logos and assign them to the order payment gateways with just a few simple clicks.

Client Area

An exemplary ordering process in the client area where the 'Twenty-One' theme is used in the WHMCS system.

Important: It is possible to use the Lagom One Step Order Form For WHMCS module without the Lagom WHMCS Client Theme. The module remains fully usable and all available features are supported when the standard WHMCS "Twenty-One" theme is used.
The only limitation concerns the number of supported styles and their color schemes. For "Twenty-One" theme, the "Modern" style with "blue" color scheme is used by default and there are no extra options to choose from.

Take a look below to see how such ordering pages may look like.

Here you can see an example of a "One Step" order form view with the 'Package Slider' option turned on, 'Sidebar' order form layout and 'Default' package type.

LOF 32.png
The next example illustrates the "Two Steps" order form view.

In this option, the first steps is dedicated to selecting product packages:

LOF 33.png
In the second step, the rest of order configuration takes place.
LOF 34.png


1. Adding a new language.

If you want to change the WHMCS module language, go to the following folder:


Copy english.php file and rename the newly copied directory with your desired language, for example italian.php. Then, open your personalized file now and replace particular sentences.

2. The module supports language Overrides.

The language file english.php is uncoded and can be freely modified. However, it is advised not to change this file itself, it is recommended to use overrides.

  • Open the overrides within the ~/lang/ directory.
  • Next, create or copy the language file you are going to change. If you want to, for example, create an override for the English language, you will have to create the following directory:
  • Open the just created file to edit its content.
  • At the top of the file you must point the used code, for example: <?php for PHP code.
  • Change the file content according to your needs. You may enter only single variables to be overridden or change all the lines in the language file.

For example:


$_LANG['order_new_product'] = 'You’re almost there! Complete your order';


 $_LANG['order_new_product'] = 'Complete the order';
3. Additional URLs used as direct shopping cart links.

Linking to WHMCS with additional URLs is supported by the module, yet only the two below formats are allowed, make sure you do not use any other format:


  1. ?promocode=testcode
  2. promocode/testcode


  1. ?billingcycle=annually
  2. billingcycle/annually


  1. ?addons=10,22
  2. addons/10,22

Exemplary supported links with additional variables used:

  2. https:/
4. The module supports URLs leading to a product page with specified configurable options and currency.

Exemplary URL:  


  1. a=confproduct - required parameter
  2. configOption1 - stands for the configurable option name
  3. 5 - value, e.g. ID configurable option value  


  1. domain - required parameter
  2. - target domain name to search
