Self-employed professionals need powerful software tools to manage their daily tasks. The increasing need for mobility support in combination with the emergence of Internet-based services make SaaS solutions an attractive option for freelancers to manage their business. In this paper, we present ORBI, a SaaS solution especially designed to meet the needs of self-employed professionals that is currently available in the Greek market. We present the key concepts behind the design and implementation of the ORBI solution and we discuss its main value proposition. Furthermore, as part of the ongoing and future research activities we present the main research directions in an effort to use ORBI as an industrial test bed to test and validate innovative concepts and tools.
