This study aims to explore the working methods used by service providers in Germany when working with women affected by sex trafficking, as well as connected challenges and how these can be tackled. The authors used a qualitative research approach, semi-structured interviews were used as a data collection tool. The participants of the study consisted of four service providers working with women affected by sex trafficking in Germany. The collected empirical data was analysed with the ecological systems theory. The collected data was divided into three themes: methods and interventions, challenges, and tackling challenges and desired changes. These themes represented the most important information collected within this study.  These findings illustrate trust-building as the most important method to effectively work with women affected by sex trafficking. Besides that, one of the key challenges identified was lack of awareness and misconceptions on the issue of sex trafficking.
