Though studies have recently examined the effect of the coronavirus on micro and small enterprises (MSEs) and the role digital technologies could play in mitigating those effects, little attention is paid to which digital tool is likely to have the most significant impact on MSEs' performance. This notwithstanding previous findings that most MSEs are reluctant to embrace digitization due to the need for more evidence on what works best for them or digital tool to adopt first. From the resource-based view theory's perspective, the study sought to examine the most effective digital technologies for MSEs' survival post-Covid-19 era. Quantitative data from 375 MSEs in Ghana was analysed using PLS-SEM. The results show that though all four digital technologies examined in the study significantly influence the survival of MSEs in the post-Covid-19 era, the adoption of social media as a digital resource will have the most significant influence on their survival.
