How to Set Up Cron Job in WHMCS

WHMCS is designed to automate many of the day-to-day tasks involved in managing a hosting business. From generating invoices and processing payments to sending renewal reminders and managing hosting accounts, automation plays a critical role in ensuring smooth operations. At the heart of this automation system is the WHMCS cron job.

A cron job is a scheduled task that runs automatically on your server at specific intervals. WHMCS uses cron jobs to execute various automated functions that would otherwise require manual administration. Without a properly configured cron job, important processes such as invoice creation, payment reminders, service suspension, and domain synchronization may not work correctly.

After logging in, locate the server management section where scheduled tasks can be configured.

 

 

Step 2: Open the Cron Jobs Section

In cPanel, scroll to the Advanced section.

Click on Cron Jobs.

This area allows you to create automated tasks that run on a predefined schedule.

If you are using another control panel, the location may vary slightly, but the process remains similar.

 

 

Step 3: Create a New Cron Job

Enter your preferred email address and click Update Email.

 

 

Next, create a new cron job schedule.

WHMCS recommends running the cron every five minutes.

Enter the following schedule:

*/5 * * * *

Running the cron every five minutes ensures that all scheduled tasks are processed promptly and reliably.

 

 

Step 4: Enter the WHMCS Cron Command

Example:

php -q /home/username/public_html/whmcs/crons/cron.php

Replace:

/home/username/public_html/whmcs/

with the actual path to your WHMCS installation.

 

 

You can find the recommended cron command by logging into your WHMCS Admin Area and navigating to:

Entering the correct command is extremely important because an incorrect path will prevent automation tasks from running successfully.

Step 5: Save the Cron Job

Add New Cron Job
