The core success of digital transformation among small and medium enterprises (SMEs) still needs to be clarified and comprehensively discussed. Meanwhile, SMEs cannot exploit digital advantages due to their limited strategic empirical and practical knowledge. This study aims to (1) describe the research pattern in the SME’s digitalization area; (2) identify the core success factors of SMEs' digital transformation to gain business success; (3) search for relevant business aspects that are necessary for SME digital transformation; and (4) develop further research agenda in the field of SMEs’ digital transformation. This study uses a systematic literature review and thematic analysis to determine core success factors suggested by primary studies. The literature review suggests that (1) SMEs should consider their baseline, limitation, and idiosyncratic to develop an aligned digitalization strategy; (2) SMEs should consider starting with incremental and gradually improving digitalization; and (3) SMEs should commit to investing in education and continuous learning.
