Quality control is a theme from AppThemes that allows you to turn WordPress into a ticketing system. It allows you to keep track of project development, have users submit bugs and log tickets.
Quality Control allows users to create tickets, assign statuses, set priorities, milestones, categories, and tags. Other users can then interact with the tickets, updating their state, milestone, adding comments, and more. Set up one or multiple projects – each with custom user groups to limit access on different projects.
