Effective public financial management (PFM) systems rely on robust audit trails and transparent reporting mechanisms to ensure accountability, detect irregularities, and maintain institutional integrity. Across emerging economies, however, weaknesses in audit documentation, inadequate financial disclosure, and poor internal control practices continue to undermine fiscal responsibility and erode public trust. This study empirically examines the interrelationship between audit trails, financial transparency, and internal control effectiveness within public financial management systems across Nigeria, Kenya, and Ghana. Using a quantitative cross-sectional design, data were collected from 420 respondents drawn from ministries, departments, and agencies (MDAs) in the three countries. Structured questionnaires measured audit trail quality, transparency indicators, and internal control performance, while regression analysis determined the predictive influence of audit trails and transparency on control effectiveness.

Results revealed that audit trails and financial transparency jointly explained 52 percent of the variance in internal control effectiveness across the sample. Organizations with comprehensive audit documentation, digitized transaction records, and timely financial disclosure exhibited significantly higher control scores than those relying on manual or fragmented systems. Among the three countries, Kenya demonstrated the strongest correlation between digital audit trail integrity and control performance (r = 0.72, p< 0.01), reflecting the impact of its integrated financial management information system (IFMIS). Conversely, Nigerian institutions showed relatively weaker associations, attributed to low automation and irregular financial reporting. Regression results further indicated that audit trail strength (β = 0.46, p< 0.001) and financial transparency (β = 0.33, p< 0.001) are significant predictors of internal control effectiveness.

The findings emphasize that strengthening audit trails through digital integration, regular reconciliation, and secure data archiving enhances not only accountability but also operational control within PFM systems. Financial transparency acts as a reinforcing mechanism that promotes compliance, mitigates corruption risk, and builds stakeholder confidence. The study concludes that institutionalizing real-time audit documentation and open financial disclosure practices are indispensable for effective internal control and fiscal governance in developing economies. Policy recommendations include investment in audit automation, capacity building for internal auditors, and mandatory disclosure frameworks aligned with international public sector accounting standards.
