The Impact of ERP Systems in Internal Auditing: The Portuguese Case

Abstract

Nowadays, internal audit procedures are increasingly supported by the use of technological tools, such as integrated ERP (Enterprise Resource Planning) systems, aiming to improve the performance of internal auditors, as well as the effectiveness and efficiency of their work. In fact, the adoption of these systems, together with a good implementation strategy, enhances the strengths of a business, while mitigating its weaknesses. This study, through a questionnaire, aims to understand the impact of ERP systems on internal audit work in Portugal. Starting by understanding which systems, modules and functionalities are most used, the study also aims to assess how these systems influence the effectiveness and efficiency of audit work and also the level of satisfaction of internal auditors in their use. The main findings show that there is a wide variety of ERP systems used by internal auditors in Portugal, the most used being SAP ERP, and the Financial Accounting, Treasury and Purchasing modules. It is also concluded that internal auditors agree that the use of ERP functionalities positively influences the effectiveness and efficiency of their work, and they are generally satisfied with the use of these functionalities in their work.
