Internal Audit

Internal Audit is the set of procedures for measuring internal controls of an organization, with the objective of better guaranteeing the quality and security of accounting information, as well as regulatory information relevant to the business.

Through its work activities, it serves the administration as a means of identifying whether the internal processes and policies defined by the company, as well as accounting and internal control systems, are being effectively followed and that the transactions carried out are reflected in the accounts in accordance with the criteria previously defined.

It is an activity designed to observe, inquire, question, check and propose changes and procedures, with the purpose of evaluating the efficiency and effectiveness of operational and financial controls and mitigating business risks.

Who does it apply to?


Internal audit (AI) strengthens corporate governance and the company's operation through risk-based audits that provide assessment and knowledge about the processes and structures that lead the organization to success.

How can we help?

Our internal audit expertise can add value by providing guidance and consulting services aimed at improving operational and governance processes, risk management and control, as long as internal audit does not assume management responsibilities.

This is vital to maintaining internal audit objectivity and avoiding conflicts of interest.

The choice of the types of audits or services to be performed should be based on the authority, maturity and purpose of the audit activity, as well as the organization's needs and problems.

We independently assess the internal audit function, analyzing compliance with the Internal Auditors Institute's standards and market practices, as well as assisting in the implementation of the internal audit area in organizations.

We carry out training for the internal audit team, as well as mapping and optimizing business processes, identifying risks and other advisory services, so that we can deliver added value to the company as a whole.
