Addon Modules

Addon modules allow developers to extend the functionality of WHMCS further including new pages in the Admin Area or Client Area. You can enable, disable, and manage them in the WHMCS Admin Area.

You can access this feature at Configuration () > System Settings > Addon Modules.

You can find more addon modules to download and install in the WHMCS Marketplace.

Enable and Configure an Addon Module

Before you can configure an addon module, you must upload it to your WHMCS installation. To do this, unzip and upload the addon module’s files to your installation’s /modules/addons directory.

To activate and configure an addon module:

  1. Click Activate for the addon module that you wish to enable.
  2. Click Configure.
  3. If the addon module has includes module-specific settings, configure them.
  4. Select the administrator roles to allow to access the addon module in the Access Control section.
  5. Click Save Changes.

The addon module will now appear in the Addons menu.

Deleting Addon Modules

Disabling an addon module may delete relevant data from the database.

To remove an addon module, click Deactivate for that addon module.

After you deactivate the addon module, you can delete the directory for the addon module from the /modules/addons directory.

  • We strongly recommend that you perform a full database and filesystem backup before deleting modules from your WHMCS installation.
  • If you are using a custom or third-party module, check with the module’s developers for any additional steps to perform before deletion.
