The purpose of this study was to substantiate the theoretical and applied principles of creating a mechanism for integrating key performance indicators into the financial controlling system of enterprises in Kyrgyzstan to enhance the effectiveness of management decisions and ensure transparency of financial monitoring. The research combined theoretical analysis, legal evaluation, and practical testing of the effectiveness of models using performance indicators in controlling. Scientific approaches to indicator formation were examined, and the regulatory framework of Kyrgyz financial control – including the Constitution, the Budget Code, and strategic national development documents – was analysed in detail. The practical component focused on the activities of Open Joint-Stock Company “Kyrgyztelecom,” Open Joint-Stock Company “RSK Bank,” and Open Joint-Stock Company “Eldik Bank,” which applied performance indicators to manage and improve financial results. Following implementation, Kyrgyztelecom’s profit increased to 107.7 million soms or 1.23 million dollars, while banks demonstrated higher transparency of reporting and enhanced quality of controlling procedures. The main barriers identified included the absence of a unified national standard, insufficient digitalisation, shortage of skilled personnel, and fragmentation of information systems. Based on the obtained findings, a six-step algorithm for integrating performance indicators into financial controlling was developed, enabling the transition from reactive to proactive management and strengthening analytical coordination across management levels. The practical significance of the study lies in offering enterprises a structured methodological framework for adapting performance-based controlling systems to national and sectorial economic conditions
