WHMCS's automation can perform many actions to help you handle tickets. You can configure escalation rules for support departments, or automate closures for inactive tickets.
The Support tab in General Settings allows you to configure settings for the support ticket system. You can choose your ticket number mask format, alter how departments display to clients, enable knowledgebase article suggestions during ticket creation, and more.
When you set up your WHMCS installation, you must set up the system cron job. The system cron controls all of WHMCS's automation, including daily tasks like generating invoices and sending email notifications.
