I was thinking of buying a ticket system where customers can just log in and raise support questions. That way I will have a nice one-way overview of all incoming questions. Furthermore, I'm looking for a kanban based task system to keep track of all work.
I was thinking of Jira, because it's relatively cheap and when I used to work for an employee, we also used Jira to keep track of tasks, so I'm quite comfortable and experienced with using it. Furthermore, I keep all git repos of client projects stored in BitBucket. Jira has good integration with Bitbucket and allows commits to auto close tickets and this makes it easier to keep track of all the work I did for a particular project. However, I don't really work with release cycles and tights sprints (yet? I'm still figuring out what workflows work best for me), so I think that Jira may be overkill.
Does anyone else use a formal ticket system for client questions? What other viable alternatives exist?
