PurposeMost of the research studies on entry mode have been done through the lens of manufacturing firms from mature economic countries entering the Global South countries, and most of the related frameworks and theories have been developed to explain this perspective. This paper presents an understanding of entry mode strategies of services firms from the Global South countries entering into countries with mature economies by considering six software services firms in India entering the US market. The study develops a framework that incorporates multiple theories – both from an emerging economy perspective as well as a services perspective.Design/methodology/approachThis study is exploratory in nature and focuses on the how and why aspects of strategic decisions. Qualitative research has traditionally been chosen when the main research objective is to improve understanding of a phenomenon. A multiple case study approach was used in this research. One of the key aspects of this study is the impact of different theories (institutional, network and other theories) on enterprises of different sizes. Therefore six cases – two each on small, medium and large enterprises – were selected.FindingsResults identify addressable market size, cultural aspects, firm size, resource and service characteristics as dominating factors that influenced choice of entry modes. From a theoretical perspective, the author finds that theories such as transaction cost theory, eclectic paradigm and other popular theories associated with entry mode do not successfully explain the entry mode strategies for firms from the Global South. Strategic theory, such as resource-based view, motivation of a firm, have some application but do not explain, in isolation, all aspects of the entry mode choices.Research limitations/implicationsThe study is an exploratory study and needs more data to validate the themes expressed in its conclusions. The study also focused on one industry and one country. Different industries within the same country may have different characteristics and may not follow the observations found in this study. Similarly, firms from other countries with similar economic characteristics may exhibit very different behavior. As a result, the themes that were expressed for software companies in India may not be generalizable across other industries and countries.Originality/valueThis study is significant for both academics and managers. For academics, the study addresses a significant gap in the literature. For managers, this study provides a framework for managers to evaluate and select the entry mode strategy that would be most effective in a successful expansion into foreign countries.
