General Background Zakat institutions require modernized technological solutions to manage public funds with high accountability and operational speed. Specific Background Lazismu faces operational bottlenecks in manual donation recording and financial reporting, which hinders public trust and organizational performance. Knowledge Gap Existing web platforms for charitable donations often lack integrated real-time tracking combined with automated multi-channel payment verification tailored for non-profit zakat management. Aims This study aims to develop and implement an integrated web-based donation information system to streamline donation collection and public reporting workflows at Lazismu. Results Built using JavaScript, React, Node.js, and MongoDB through Agile methodologies, the developed system achieved a 30% reduction in processing time during functional black box testing while providing transparent automated visual financial dashboards. Novelty The platform combines agile full-stack architecture with localized automated reporting mechanisms designed specifically for Islamic philanthropic operations. Implications Deploying this digital architecture provides non-profit management with scalable tools to increase public credibility, accelerate fundraising workflows, and modernize charitable fund distribution. Key Findings Highlights Full-stack web system integration streamlines donation collection and reporting workflows. Automated visual reporting features provide public access to verified financial transaction data. System implementation demonstrates a 30% reduction in donation data management processing time.
