PurposeThe purpose of the current paper is to identify the factors responsible for achieving business sustainability. This paper further attempts to develop a conceptual framework that can help SMEs to achieve viable business growth through improved sustainable performance.Design/methodology/approachThe study follows a methodical examination of literature published on SMEs during COVID-19. Specifically, the combination of keywords has primarily centred on SMEs, Business Practices, COVID-19 and Pandemic. The 155 research papers identified for the analysis have been classified as per geographical spread, type of papers, central theme, and theoretical foundations, which finally is followed by rigourous thematic analysis.FindingsThis research contributes to the SME literature by providing methodological, conceptual and practical rigour. The framework proposed by the research covers all the relevant areas which can be useful in preparing sustainable business trajectory for SMEs. It outlines the required directives for designing sustainable business practices for SMEs and includes macro and micro determinants. It also opens up future research avenues in different areas identified in the research. Future research can be performed on comparing business practices of SMEs across the emerging and developed economies.Practical implicationsIn this study, we propose a framework that enables the design of sustainable business practices and thereby supports SMEs to combat any uncertain events or shocks. SMEs that can work on adopting sustainable business practices may sculpt novel avenues for growth and competitive advantage for their business.Originality/valueThe study is distinctive in nature as it is based on the examination of literature published during a phenomenological event (COVID-19) which depicts the sudden and unaccounted disruptions faced by SMEs and thereby strategies formulated around the significant glitches.
