Purpose: The Indonesian Government has high procurement corruption. Implementing electronic procurement poses numerous challenges, as it can still provide opportunities for corruption. This study aims to examine how implementing e-procurement reduces corruption through user perceptions. Design/methodology/approach: For the analysis, this study applied a mixed-method approach by distributing questionnaires and conducting interviews to procurement actors from ministries, institutions, provincial governments and suppliers of government goods and services. The primary data were analyzed using the structural equation model SmartPLS and NVivo software. Findings: The empirical results show that the implementation of e-procurement is significant in reducing corruption in the Indonesian Government. Research limitations/implications: This study did not accommodate local government for more numerous government respondents. Practical implications: This study highlights that the government assesses the implementation of e-procurement higher than the supplier when suppliers more agree with the existence of procurement corruption than the government. Originality/value: By employing the technology acceptance model, this study shows how the ease of use and usefulness of e-procurement affect corruption in the procurement process. © 2025, Emerald Publishing Limited.
