The study focused on examining the relationship between E-procurement and organizational efficiency at LTA Juba Ltd, a leading clearing and forwarding company in South Sudan. The main purpose of the research was to investigate how e-procurement contributed to improving the efficiency of procurement processes and overall operational performance within the company. The study sought to fulfill the following three objectives: to examine the effect of E-sourcing on organisational efficiency of LTA ltd Juba, to examine the effect of E-tendering on organisational efficiency of LTA ltd Juba and to examine the effect of E-payment on organisational efficiency of LTA Juba. A descriptive research design was employed for this study, targeting the employees of LTA Juba Ltd as the population. The total study population comprised 100 employees, from which a sample size of 80 respondents was selected using Krejcie and Morgan's sampling formula. The study utilized both quantitative and qualitative methods for data collection. Questionnaires were the primary data collection tool for quantitative data, whereas interviews were conducted to gather qualitative insights. The collected data were analyzed using SPSS software to perform both correlation and regression analysis, with the findings presented through tables, to show the descriptive statistics, and inferential statistics. The study concluded that E-sourcing significantly enhanced the organizational efficiency of LTA Ltd Juba, with a Pearson correlation coefficient of 0.672 indicating a strong positive relationship and a statistically significant p-value of 0.000. Regression analysis revealed that approximately 43.6% of the variance in organizational efficiency could be explained by E-sourcing. Additionally, the study found that E-tendering also positively affected organizational efficiency, albeit to a lesser extent, with a Pearson correlation coefficient of 0.314 and a significant p-value of 0.016. The regression analysis indicated that 22.6% of the variance in organizational efficiency could be attributed to E-tendering, showing that while it contributed to performance, other factors were also crucial in influencing efficiency at LTA Juba. The correlation and regression analyses revealed a strong positive relationship between e-payment systems and organizational efficiency. The Pearson correlation coefficient of 0.821 indicated a significant correlation, with a p-value of 0.000, confirming that improvements in e-payment directly relate to increased efficiency. The regression analysis demonstrated that approximately 72.4% of the variance in organizational efficiency can be explained by changes in e-payment, highlighting its substantial predictive power (R = 0.821). To improve organizational efficiency at LTA, the study recommended that the LTA’s IT Department should implement an advanced E-sourcing platform, the Procurement Team conduct regular training, and Senior Management allocate a budget for system improvements. For E tendering, the Procurement Team should create standardized templates, the Finance Department implement a secure payment gateway, and the Quality Assurance Department conduct regular audits. To enhance E-payment, the management should conduct staff training on E-payment systems, the IT department should upgrade the infrastructure with real-time tracking and automated invoicing features, and the finance department should set up monitoring protocols to evaluate e-payment effectiveness.
