Evaluating the Effectiveness of a Computerised Accounting System for Financial Management in Nigeria

This study examines the effectiveness of computerised accounting systems (CAS) in enhancing financial management within Nigerian commercial banks. Although CAS has become essential for improving operational efficiency, accuracy, and competitive advantage, Nigerian banks continue to face major challenges including cyber-insecurity, system failures, and operational risks. These unresolved issues raise concerns about whether computerised systems truly contribute to improved profitability, performance evaluation, and reliable financial management. Therefore, this study aims to assess the extent to which CAS adoption has enhanced efficiency and profitability in Nigerian banks; explore how operational and security challenges affecting CAS effectiveness are currently being addressed; and determine the specific impact of these challenges on financial management outcomes. The study adopts a positive and quantitative research design, using structured online questionnaires administered to 100 banking staff in Lagos State, selected through convenient sampling. Data will be collected through Google Forms, organised using Excel, and analysed statistically using SPSS. The expected findings are that while CAS improves speed, accuracy, and operational performance, security vulnerabilities and infrastructural limitations continue to weaken overall effectiveness. The study anticipates identifying key gaps in system integrity, staff training, and technological readiness that influence financial management outcomes in Nigerian banks. However, the study is limited by its focus on Lagos alone, its reliance on self-reported data, and the use of convenience sampling, which may restrict the generalisability of findings. Despite these limitations, the research will provide valuable empirical evidence on CAS performance and offer insights to guide policy, system upgrades, and security improvements across the Nigerian banking industry.
