Company management is a highly sophisticated activity which must employ the latest information technologies as ongoing digitisation allows company processes to be managed in a dynamic way, primarily with respect to the fast-changing economic environment. This also applies to internal audit, which helps to ensure flexible transfer of data concerning process deficiencies to the company leadership. The aim of the study is to verify the efficiency of the digital potential of the internal audit in the field of marketing, which forms an important part of company management. The method of the paper includes an analysis of the current theoretical background as well as an analysis of marketing risks and the use of adequate auditing techniques. The proposed system of internal audit, or the use of digital methods, can subsequently be used to predict process deficiencies, and thus contribute to efficient risk management and responsible business conduct.
