Nexus between accounting and information systems and SMEs`operational efficiency in South Africa. Problems and Perspectives in Management. 21(2): 493-502. doi:10.21511/ppm.21(2).2023.461727-70511810-5467 (Online)https://hdl.handle.net/10321/5519Accounting information systems are critical to any business but especially important to small and medium-sized enterprises (SMEs). Such systems are vital to their performance and success. Unfortunately, SMEs make poor decisions, leading to a shortage of accounting information. Hence, this study aims to investigate the impact of accounting information systems on SME operational efficiency in South Africa. Using purposive sampling, data were collected from 109 out of 150 retail SME owners or other appropriate representatives. A quantitative research design that falls under the positivist paradigm was used. The Statistical Package for Social Sciences (SPPS) software version 20.0 was utilized to analyze the collected data, specifically through descriptive and regression analysis. The study found a significant positive correlation between accounting information systems and SME operational efficiency (r-value = 0.579), which had a p-value of 0.0005, according to the intensity of the association with r-value. The study recommends that SME management implement excellent accounting principles into their operations. Furthermore, because SMEs may be unable to afford complicated accounting systems, SMEs functioning in the same region should implement a resource-sharing strategy to reduce expenses.12 pen1501 Accounting, Auditing and Accountability1503 Business and Management3507 Strategy, management and organisational behaviourAccounting and information systemsSmall and medium-sized enterprises (SMEs)Operational efficiencyArticle2024-09-1610.21511/ppm.21(2).2023.46
