Non-Governmental Organizations (NGOs) are essential to social development, as they raise and deploy funds efficiently to support welfare initiatives. Effective management of income and expenditures is crucial to guarantee transparency, accountability, and optimal resource utilization. This study centers on the Siddarth Rasi Foundation (SRF), a grassroots NGO that delivers services through volunteer efforts and is supported by donations. The research looks into how the organization earns revenue, handles donations, oversees spending, and guarantees that funds are appropriately used for social welfare initiatives. It also examines volunteer awareness and perceptions about financial management practices. The findings show that SRF operates on a trust-based, transparent financial model with low administrative expenses, allowing the majority of funds to reach beneficiaries directly. Nevertheless, the study recommends improving structured financial documentation and reporting systems to boost long-term sustainability and donor confidence.
