The main aim of this study was to analyse cost management and account management practices of public quoted manufacturing companies in Sri Lanka. Research method used in this study was an applied research method, whilst the research strategy employed was a survey research strategy. Sample for the study consisted of 70 public quoted manufacturing companies in Sri Lanka. Findings from the study revealed that the main costing method used by public quoted manufacturing companies in Sri Lanka is activity based costing, followed by process costing and job costing. Findings from the study also revealed that cost information is mainly used by public quoted manufacturing companies for pricing related decisions, followed by customer profitability related decisions, and performance measurement; that the increasing interest and use of cost accounting in these companies is on account of the decline in firm profitability, increasing cost, intense competition, and high customer and supplier bargaining power; and that these manufacturing companies give high importance to traditional management accounting practices such as planning and control, budgeting, target costing, and cost-volume-profit analysis.
