The need to standardize procedures and tackle similar questions of auditing, risk management, controlling and similar related topics is vast, especially, but not exclusively in multinational companies. However, smaller companies more and more find themselves in a position to act more globally-or at least internationally-in terms of sourcing as well as sales. This brings new needs for and new foci on topics as Internal Audit as well as Corruption Prevention. This article gives some ideas, hints and challenges towards these topics. In order to clarify the views expressed in this article, the author first gives some general information about internal audit, such as its definition, tasks and objectives, its historical development, legal background, structure and implementation, in order to make clear, on which aspects and understanding the argumentation is based. This introduction will provide a theoretical basis for the description and identification of the potential problems and possible challenges in an international perspective.

The paper presents three controlling instruments related to CSR and discusses the implementation of those instruments into CSR. The first section deals with the activitybased costing and process-oriented controlling. It shows the differences between these two approaches and stresses their contribution to identification of the non-value creating activities and waste reduction. The second section elaborates on the requirements of modern product costing systems giving a more detailed view about product life cycle costing in the CSR context. The third section focus on target costing where target costs are determined by different market approaches and thus being much more flexible to customer needs and expectations. Finally, the paper introduces a concept of green controlling as a part of CSR.
