Social enterprises (SEs) have an important role in the social services provision. Many of those enterprises provide services, such as care services to elderly people and young people at risk of exclusion, work integration services, mediation, etc. In European Union (EU) countries, public administrations are obliged to provide these services to the citizens, although they externalize the provision to SEs. In this chapter, the financial strategies of SEs are analyzed in order to assess if they have any impact on mission drift. The analysis is based on the experiences of three SEs that provide social services in Catalonia, Spain. Several interviews with managers and board members of SEs were done. The results indicate that there is an important financial dependency of these SEs on the public administration. Therefore, SEs have problems to remain mission-focused, and a mission drift into market positions has been observed.
