This paper focuses on the implementation of accounting information systems (AIS) and information technology (IT) in the sustainability of developed economic units. The objectives of this study are to characterize economic units, study the application of AIS, explain the effectiveness of AIS and IT on economic units, and investigate the role of IT specialists. To achieve these objectives, a comprehensive analysis is conducted to understand the nature, structure, and operations of developed economic units. The study explores how AIS are implemented and utilized within these units, examining the processes, procedures, and technologies involved in collecting, storing, processing, and reporting financial and non-financial data. Additionally, the impact and effectiveness of AIS and IT on the overall performance and sustainability of economic units are assessed, highlighting the benefits and challenges associated with their adoption and integration. The results obtained demonstrate the positive impact of effective AIS and IT implementation on economic unit performance, including improved decision-making capabilities, streamlined operations, and enhanced financial reporting. However, limitations such as sample size and data reliability should be acknowledged. To overcome these limitations, future research should consider larger and more diverse datasets, longitudinal studies, and the involvement of multiple stakeholders. In conclusion, this research provides valuable insights into the implementation of AIS and IT in developed economic units and highlights their significance in ensuring sustainability. The findings can inform decision-makers and practitioners in optimizing the utilization of AIS and IT
