The purpose of this study is to investigate the impact of the Covid-19 pandemic on Bangladesh's online businesses. This study focused on the growth and problems encountered by online businesses during the pandemic. The study was mainly based on primary data collected through the survey of 400 Facebook-based online businesses in Bangladesh. Descriptive statistics and correlation analysis methods have been used to analyze all the collected primary data. The findings of the study showed that online businesses experienced growth during the pandemic. The findings also revealed problems like supply chain disruption, rising costs, logistics hindrance, and financing constraints that limited online businesses to leverage the opportunity brought by the pandemic to its full extent. Furthermore, it was found that a majority of respondents think that government financial schemes can support online businesses.
