Low-cost, scalabale solution that could handle multiple trouble ticket queues within one software context.

Highly customizable. Perl backend "makes sense" and isn't opaque like some designs. It runs as a set of CGI, so that allows it to be wedged into most any webserver environment. We found it simple to run within an Apache / Linux environment.

The CGI-based design is relatively inefficient and can be sluggish without making some optimizations on the webserver side -- mod_perl in our case (relatively complicated). Docs are a bit sparse, though customer service is responsive.

It's a great daily ticket email system.

I love the ticket handling and speed of the interface. It's basic layout offers the basics you need to get up and running with a ticketing system.

The support is little to non-existent but that is expected with the free tier.

Basic software for small organization without advanced features of ITIL.

I used it for sometime in one of my assignments. It was a very basic tool with minimum customization. It just does its job and do not provide advanced features of ITIL framework. Reporting was not effective and so was its UI. We replaced this with more advanced CA Servicedesk. However as a freeware, it was good for initial use.

It is basic application and nothing much can be expected put of this. Ours is a ITIL compliant organization and need a more robust application.

Makes work easier by having a good overview of ongoing tickets, but also past tickets, with details of what was built / done to offer a solution. That's dependant of what you enter into the system of course, but the options are there and they are clear.

I've been using OTRS for quite a few years now, and it's an excellent piece of software that makes my life as a sysadmin/support desk guy easier. OTRS understands ITIL, end users and IT pros, and the software supports that. You can link tickets, make internal notes, make FAQs, paste images into text fields, send e-mails, etc. You can also do templates, customize columns, set alerts when things take too long, etc. It's really nice. It even works with our ADFS server, which is excpected of a tool like this, but still. In short, OTRS is versatlize and customizeable.

There have been minor (cosmetic) bugs here and there, every now and then, which are slightly annoying. Often you can fix these things yourself, but OTRS's configuration is very complex and requires some insight and experience. So in the end, you're gonna have to contact support or read the extensive manual. But buth those options work.

OTRS is a powerfull and complete tool to help IT engenieers to assist customers and internal enterprise clients.

May be the price and the features associated with no commercial versions, Other software with community editions has more options and other kind of level prices for small business.
