Free and open source software has many attractive qualities, perhaps none more so than the price tag. However, does 'free' really mean free? In this chapter, I consider the process of implementing FLOSS systems within an enterprise environment. I highlight the hidden costs of such deployments that must be considered and contrasted with commercial alternatives. I also describe potential business models that would support the adoption of FLOSS within industry by providing support, training and bespoke customisation. Finally, the role of pre-competitive initiatives and their relevance to supporting open source initiatives is presented.
