The movement of internalization of brazilian enterprises is primarily characterized by the displacement of industrial companies; the internalization of retail business is a more recent phenomenon. Thus, studies on the internalization process of brazilian retail companies are not numerous yet in the country. In this context, the study aimed to investigate, using the method of case study of B2W – Companhia Global do varejo, the internalization process of a brazilian eCommerce company - their motives, how it expanded their business abroad and what were their main obstacles that have been faced and the facilitating factors of the process. Acting abroad was a way for widening markets and diversifying risks for the enterprise, and nowadays, it is the focus of its growing strategy. This study has utilized secondary data retrieved from theses, dissertation, articles and internet, besides primary data collected through in-depth interviews with main company executives. Data analysis showed that theoretical framework employed in this work was present in the internalization process of the company studied.
