A CRON job, also known as a scheduled task, is a process that your web server/computer runs at preset intervals. This operation usually does things such as process management tasks, update data, or do backup at the preset time that it is configured to do so.
Here are some examples of what a CRON job does:
- Backup your data files at 1:00 AM every day to a specified archive folder
- Check for any recurring commissions that need to be created on a daily basis
- Send out email alerts every night with reports on how your system is running
Your eCommerce software requires the use of CRON jobs to run its daily management tasks and to generate invoices if needed, if any. Please check to make sure your web host supports CRON or some other sort of task scheduler whereby you can run a specific program at least every 30 minutes.
