Even if financial audit has already defined its role and responsibilities, this activity is quite new in Romania and internal audit is at the beginning of its way. Financial and internal audit need IT tools in order to fulfil their role. Romanian audit software offer is pretty poor, so the authors started a project consisting in the design and development of a specialized software application for audit missions, also able to sustain analysis not directly related to the audit activity. This paper focuses on the most important functions of the designed audit tool – planning, sampling and analysis of data. For the sampling function the application provides several ways of approach. The authors focused on this function taking into account that the accuracy of the auditor’s opinion is directly linked to the exactness of sampling. Analysis is also an important function, and data analysis process is quite time-consuming for the auditors. This module provides multiple and dynamic criteria for records selection and analysis so that the auditors can develop their research according to the objectives and activities started in the audit plan. This module can also be used for monitoring needed in the fraud detection process. The new approach of continuous audit can be sustained by this module.
