A helpdesk is the central contact point for both customers and employees with queries and other concerns. The teams that provide support or service to the customers or employees are known as the helpdesk support teams.

By using the helpdesk ticketing system, the helpdesk team can view and answer all the tickets by using the shared mailbox, can work on the pending tickets, assign the tickets to other agents, and can also review the customer history.

There are many free and open-source self-hosted ticketing systems available, but we have selected some of the best ones. The advantage of this free software is that it is flexible, scalable, provides loads of customization options, and is absolutely free to use.
