The study used a collaborative model that incorporates the Technology Acceptance Model (TAM) and the Theory of Planned Behaviour (TPB) to examine how social commerce (s-commerce) is implemented within micro, small, and medium-sized businesses (micro-SMEs). This study investigates the limited s-commerce adoption among micro-SMEs and then assesses how s-commerce affects their company's performance. To business owners in the Klang Valley, Penang, and Johor Bahru regions, 450 surveys were sent. To analyse the data, structural equation modelling (SEM) was employed. This study found that perceived usefulness, subjective norm, trust, and readiness all have a big impact on how s-commerce is adopted. Utilising user experience acted as a moderator in influencing attitudes towards adoption. This study contributed to the existing theory by incorporating the extended TAM with the TPB and additional elements. This integration enhanced our understanding of the factors influencing technology adoption, as well as the underlying motivations driving such behaviour. In the past, these models are often applied separately.
