This research is an empirical investigation into the effectiveness and satisfaction of users of a procurement audit tool in the dimensions of transparency, inconsistency checking, and fraud detection pertaining to procurement processes. Based on the feedback obtained from concerned professionals in state technical audit roles, it is found that, overall, although the tool is shown to be quite effective, the users are only moderately satisfied, particularly in regard to procedures related to smoothing. Some of the recommendations for improvement include AI integration, user interface enhancement, continuous feedback mechanisms, and comprehensive training programs. The results show the value that it currently is bringing forth but also point to still further opportunities of optimization that should be addressed in light of the changing needs of users.
