Abstract: The ‘direct method’ of presenting cash flow statements has been the traditionally preferred format because of its accuracy. However, some authorities have argued that this ‘direct method’ is too costly despite its advantages. This research presents a new method of preparation with the aim of changing the actual trend in the international context. Its advantages are fast implementation, low costs, conformity to IFRS and no dramatic changes in data processing. This paper explains all the changes needed to adapt an accounting software package to this new methodology.
