Management accounting has evolved over the years to provide information for: determining the cost of product and services and financial control; management planning and control, reducing waste of organisational resources in business processes; and creating shareholder and customer value by effectively using organisational resources. Therefore, organisations’ management accounting practices (MAPs) are crucial to improving organisational performance and ensuring the sustainability of organisations in the current competitive business environment. Existing literature, grounded in several theories, have advanced several determinants and consequences of MAPs in companies. Discuss the factors that influence the MAPs of companies and the effects of MAPs on firms. The discourse must identify and discuss the relevance of management accounting theories in explaining these determinants and the consequences of MAPs in organisations.
