Modern companies are more and more understanding the importance of sustainability and CSR practices implementation in their operational activities. The triple bottom line approach that considers ecological, economical and societal outcomes, is now considered by businesses on various levelsfrom product development and supply chain management to HR management and PR activities. As a result of stakeholder pressure, many companies understood that being a good employer means much more than just paying salaries on timeit also involves participation in the life of a wider range of company´s stakeholders. At the same time companies stop considering CSR practices as an imposed burden, but start seeing them as a contribution to an improvement of corporate image and contribution to company´s success. The current paper is aimed at understanding a contribution of voluntary micro-donations, such as rounding-up of invoice amounts, to CSR strategy of retail trade companies. It answers the following research questions: 1. What are different motivations of corporations for implementing micro donations? 2. Which customers´ needs are addressed by this form of corporate activity? 3. How micro-donations differ from other corporate-driven strategies of corporate giving?

Analyses of potential risks and challenges associated with the usage of micro-donations, as well as description of experiences of corporations taking part in the initiative are considered to provide contributions to the practitioners in the field.
