The purpose of this study was to examine factors for accounting personnel to adopt Robotic Process Automation (RPA) through an extended Technology Acceptance Model. The research model integrates the Technology Acceptance Model, the Innovation Diffusion Theory, the Technology-Organisational-Environmental framework, and Hofstede's cultural model. A survey questionnaire was administered to collect data from accounting personnel in Malaysia. Using Partial Least Squares, the results of 105 responses from the questionnaire survey showed that relative advantage, and training and education had a significant positive effect on the perceived usefulness of RPA. However, perceived usefulness had no effect on the intention to use RPA. The result suggested that even if the respondents perceived RPA to be useful, they have little intention to use RPA in their task automation. Nevertheless, this study could contribute to the literature of RPA adoption in the accounting field by providing the theoretical base for examining the perception of accounting personnel on the intention to use RPA through an extended TAM. Determining the factors that affect accounting personnel's behavioural intention to use RPA is expected to help managers make better decisions when adopting RPA in their organisations.
