Many IFES (Federal Higher Education Institutions) in Brazil use integrated management systems, which are well known as ERP (Enterprise Resource Planning) systems. These systems usually are quite comprehensive, expensive and they still in use for a long time until be replaced. So, their costs shall be evaluated, not only acquisition costs, but mainly maintenance and support costs. Therefore, in order to define these cost elements of ERP systems in Brazilian IFES, a literature review was conducted and a set of these costs is proposed based on the TCO (Total Cost of Ownership) methodology and supported by the financial management process framework ITIL (Information Technology Infrastructure Library). Five experienced specialists on ERP systems have validated these costs elements set on literature review. Afterwards a survey with 41 experts in ERP systems from Brazilian IFES was conducted, in order to inquiry their perceptions about the relevance of these cost elements. The study results in a classification for the highest cost elements in Brazilian IFES, which greatly contributes to assist decision makers not only to adopt these elements for measurement of maintenance and support costs of ERP systems in use, as well, help them to draw the IFES's strategic planning.
