What is OTOBO?

OTOBO is an extremely flexible, web-based open-source ticketing tool, used to streamline communication in service organisations such as IT Helpdesks, Customer Service, Call Centers etc.

It provides classical ticketing functionality, a knowledgebase/FAQs with internal and external interface, helps to automate processes and can be extended by an ITSM component with a CMDB to keep track of IT components – or buildings, office plants, cars etc.

OTOBO is a fork based on ((OTRS)) Community Edition, started in 2019 to go back to the roots and offer a 100 % free tool, rooted in a strong community, and backed up by professional business services.

Professional Services for OTOBO

OTOBO is a mighty and highly flexible tool. Pretty much everything can be individualized and adapted to your needs. And more often than not there is more than one way to achieve a goal.

No reason to feel overwhelmed, though. We are happy to help adapt the system optimally to your needs, make sure you take full advantage of it, and assist in securing your operations. There’s also a fully managed version of OTOBO if you do not want to take care of that yourself.

We are Rother OSS GmbH, source code owner of OTOBO. Founder Stefan Rother was first employee of OTRS GmbH back in 2004, and created Rother OSS when he left there in 2011. We have been working with the ticketing tool ever since, and know what we are doing.
