To start using WHMCS, you will need to install it on your server. You may need help from your hosting provider or system administrator to do this.
You can also learn about installing WHMCS by watching the video below.
First, download the current Full Release version of WHMCS:
- Go to download.whmcs.com.
- Under Full Release, find your desired WHMCS version and click Download.
We always recommend the latest version of WHMCS, which is highlighted at the top of the list.
Next, install the software to your server.

To do this:
1. In cPanel, go to the MySQL Database Wizard interface (Databases >> MySQL Database Wizard). This interface will guide you through the process of creating the WHMCS database.
2. Use the interface to choose a database name, username, and password, and to set permissions.
3. When you reach the Privileges section, choose All Privileges.
Make sure to note the database details, since you will need them later in the process. For databases, cPanel uses the cPanel account username, an underscore, and then the database name or username.
4. In a separate browser tab, go to
example.com with your website address.
5. Read and click Agree for the End User License Agreement.
6. Follow the instructions in each step of the installation process to provide your database information, license key, and other information.
You can find your license key in the Client Area or in your welcome email.
7. To finish, click Complete Setup.
Make sure to copy and save the daily cron job command (in grey). It's unique to your server and you will need it later in the process.
8. When you see the Installation Completion page, remove the
/install directory from your server. To do this, right-click the
/install folder in cPanel's File Manager interface and choose Delete.
