The study investigated efficiency management on the financial performance of listed Consumer Goods Firms in Nigeria. Specifically, the study examined the effect of Inventory Turnover Ratio (INVTR), Trade Receivable Turnover Ratio (TRTR) on Return on Assets (ROA). Firm size was introduced in the model as a control variable. The design of the study was Expo-Facto. Data covering 10 years (2013 -2022) was obtained from the annual reports of five (5) companies selected from twenty-one (21) firms in the Consumer Goods sector through judgmental sampling technique. Techniques of data analysis include descriptive analysis and panel regression technique. Results revealed that the inventory turnover ratio had significant positive effect on ROA while there was no evidence of significant effect of Trade Receivable on ROA. However, firm size had significant positive effect on ROA. Based on findings, the study concluded that efficiency management improves the financial performance of listed consumer goods firms in Nigeria. Based on these findings, the study recommended the adoption of efficient inventory techniques such as demand forecasting, vendor management, planning of materials required by firms, and economic order quantity for management of inventory. The study also recommended the use of practices such as establishing payment terms, offering cash discount, providing customers with multiple payment options, adopting shorter collection period, the use of reminders before due date in management of trade receivables.
