Digitalization is playing an increasingly important role in the growth of small businesses and is leading to structural and strategic transformations. For micro-small and medium-sized enterprises (MSME) which decide to engage internationally, the use of digital infrastructures presents new opportunities to succeed in foreign markets. This paper aims to jointly study research streams investigating the internationalization and digitalization of small businesses. Through a literature review, this article presents an overview of International Business theories and justifies the need to introduce the digital context in theoretical internationalization models. By linking these dimensions, the study demonstrates how digitalization impacts on international trade. It also highlights opportunities for MSME to define a new international value proposition through digital infrastructures. To conclude, the article discusses avenues for future research and managerial implications.
