This study analyzes the influence of implementing accounting, managerial, and technology methods on the financial performance of small and medium enterprises (SMEs). The implementation of accounting methods was reflected based on the dimensions of intellectual capital, internal control system, and the availability of financial statements. The managerial methods, on the other hand, were reflected by business strategy, market orientation, and total quality management. Meanwhile, the technology was reflected by the payment gateway, receipt services, and e-commerce dimensions. As a case study, this study sampled 220 SMEs with a turnover of around 300 million to 2.5 billion rupiahs per annum in South Tangerang City. We chose SMEs in this city because it is one of the areas with the highest economic growth in Indonesia. Therefore, the development of SMEs in this city would likely be an excellent example of SMEs in other regions in Indonesia. Using the structural equation modelling partial least square (SEM-PLS) estimator, this study revealed that accounting and managerial methods positively influence SMEs' financial performance. However, this study found no evidence that technology adoption influences it. It implies that SMEs were still unfamiliar with technological adoption. The investments issued by SMEs to adopt technology seem unable to create the expected rate of returns.
