This study examines the correlation between inventory and accounts payable management and the profitability of construction companies listed on the Johannesburg Stock Exchange (JSE). The annual financial statements of all 13 listed construction businesses from 2009 to 2019, including statements of financial position and financial performance, were obtained from an external database for statistical analysis. The study employed multiple linear regression to assess the impact of working capital management on the financial performance of construction companies listed on the JSE. Additionally, a correlation model was utilised to investigate any potential relationships among the variables being examined. The study's findings indicate that the management of working capital has a notable impact on the profitability of construction companies listed on the Johannesburg Stock Exchange (JSE) in South Africa. Despite contradicting findings from other studies that support the opposite conclusion, this study demonstrates that effective management of working capital does not necessarily lead to a positive relationship with financial performance for financial managers of construction companies. Therefore, it is crucial to consider other aspects of management in addition to working capital.
