These barriers are provided in the form of Lack of activity-based costing system elements and with respect to similar cases in America, Britain, Canada, Australia, Germany, France, and similar studies in Iran. The results of this study showed that in Companies listed on the Tehran Stock Exchange, major barrier in implementing activity-based costing systems are lack of proper design and implementation of activity-based costing systems, low degree of automation, lack of necessary infrastructure, lack of support from top managers, lack of customer-oriented thinking, low diversity of products, and lack of trained manpower.
