Measuring the social impact of social enterprises remains one of their key challenges. Yet, at the same time, non-financial reporting methodologies developed primarily for large corporations do not reflect social enterprises’ heterogeneous characteristics and the wide array of their impacts. Social enterprises also have limited competencies and resources available to dedicate to these activities. Responding to these challenges, the model that we have developed aims to devise an effective tool to identify, evaluate and report relevant social impacts and guide social entrepreneurs in the process of creating change in society. The tool integrates contemporary theory and methodologies, frameworks, standards and guidelines that better fit the specific features of social enterprises. An advantage of the tool is its flexibility in being able to capture different social impacts and adapt to various levels of entrepreneurs’ measuring skills. Moreover, being partly standardised, the tool enables aggregation of the collected data for policymaking purposes.
