Introduction. In the current context of economic instability, exacerbated by global challenges and the consequences of war, the development of effective mechanisms for financing sustainable development of enterprises has become particularly important. Achieving a balance between economic efficiency, environmental responsibility, and social justice requires the implementation of advanced financial technologies, improvement of institutional approaches, and the mobilization of investment resources. Purpose of the study. The purpose of this article is to analyse the theoretical and methodological foundations for implementing sustainable development financing systems in domestic enterprises and to develop models that will contribute to the effective achievement of sustainable development goals in the national economy. Research methodology. The study employs a systematic approach, methods of economic modelling and forecasting, analysis of recent scientific publications, and examination of external and internal factors influencing the financing of enterprises' sustainable development. Research results. The article clarifies the concept of "sustainable development," identifies its main characteristics and influencing factors on financing. A model for implementing sustainable development financing systems for enterprises is developed, taking into account the specificities of the sustainable development process, the particularities of enterprises as modelling objects, the application of innovative financial technologies, and the mobilization of investment resources. Key barriers to the implementation of these systems in Ukraine are identified, and the necessity of digitalizing sustainable development processes is substantiated.
