Cron tasks must be created to automate tasks within WHMCS.

Cron is the name given to a system daemon used to execute tasks (in the background) at designated times. WHMCS has a number of files that are required to be run on a periodic basis in this way. All these files are located in the crons directory.

A single cron named the System Cron automates all core functions of the system including invoicing, reminders, suspensions and other daily automation tasks.

In WHMCS 6.3.x and earlier, the system cron should be configured to run no more than once per day.

In WHMCS 7.0 and later, the system cron should be configured to run as often as every 5 minutes or as frequently as your web hosting provider will allow (for example, every 15 minutes). The shortest time interval at which WHMCS will process cron tasks is every 5 minutes.

Setting Up Cron Jobs

The tutorials & screenshots below demonstrate how to configure the WHMCS cron on the most common hosting control panels.

The system will attempt to determine the PHP path to use for your cron command. You can find this when you click on the first badge at Configuration () > System Settings > Automation Settings or, prior to WHMCS 8.0, Setup > Automation Settings.

cPanel

Click on the Cron Job icon in cPanel, select the Once Per Five Minutes option from the Common Settings menu. Then paste the cron command into the Command field.

Alternatively, click Advanced (Unix Style) and enter:

cPanel Cron
Option Minute Hour Day Month Weekday Command
a) */5 * * * * php -q /path/to/home/public_html/whmcspath/crons/cron.php
b) */5 * * * * wget -O http://www.example.com/whmcspath/crons/cron.php >/dev/null
c) */5 * * * * GET http://www.example.com/whmcspath/crons/cron.php

Direct Admin

The command for Direct Admin is generally the same as cPanel, however, you need to reference the full path to the php binary.

Depending on your server, this will be /usr/bin/php, /usr/bin/home/php or /usr/local/bin/php. Check with your hosting provider or system administrator for the full path to the PHP binary.

An example command to run is:

Command
/usr/bin/php -q /home/demo_user/domains/testdomain.com/public_html/whmcspath/crons/cron.php
/usr/local/bin/php -q /home/demo_user/domains/testdomain.com/public_html/whmcspath/crons/cron.php
wget -O /dev/null http://domain.tld/path/to/cron.php
GET http://www.example.com/whmcspath/crons/cron.php

DotNetPanel

Navigate to the hosting space in which WHMCS is installed and click Scheduled Tasks from the Hosting Space Menu, then click Add Scheduled Task.

From the Task Type dropdown menu select the Check Web Site Availability option and enter the URL of the cron.php file into the URL field. Use the Schedule options to run this task Daily and finally ensure it's active and running.

Windows Server

Depending on your server setup, you can run the cron directly from the php executable. If this is not possible, you would need to use the server browser to run the cron

An example command to run is:

Command
C:\php\php.exe -q "C:\inetpub\wwwroot\whmcs7\admin\cron.php"
"c:\program files\internet explorer\iexplore.php" "http://www.example.com/whmcspath/cron.php"

You should then set the task to run at a certain time every day. The time is up to you.
