Abstract: THE IMPACT OF COST ACCOUNTING FOR JOB ORDER AND PROCESS COSTING SYSTEMS: A CASE STUDY OF COCA COLA
This study examines the impact of cost accounting on job order and process costing systems, focusing on Coca Cola's operations in Lagos. The objectives are to analyze how cost accounting supports these costing systems, assess their impact on financial performance, and identify the challenges faced. A survey design was employed, with data collected from 250 financial managers and cost accountants, derived using Taro Yamane's formula. A detailed case study of Coca Cola in Lagos provided comprehensive insights. The reliability coefficient score was 0.88. Findings reveal that cost accounting plays a crucial role in managing job order and process costing systems by providing detailed cost information and facilitating better decision-making. However, challenges such as data collection difficulties and compliance issues were noted. Recommendations include providing more training on cost accounting for these costing systems, simplifying data collection processes, and integrating cost accounting with other financial management practices to enhance overall performance.
