Abstract : Traditional paper-based receipt systems are increasingly seen as environmentally unsustainable, operationally inefficient, and vulnerable to fraud. With growing digital transformation, cloud computing offers scalable, secure, and eco- friendly alternatives. This paper presents the design and implementation of an E- Receipt Generator using Cloud Computing, developed with Flask (Python) for the backend, Bootstrap for the frontend, AWS RDS (MySQL) for cloud storage, and Chart.js for analytics. The system enables dynamic item entry, automatic calculation of totals and GST, UPI QR code generation for seamless payments, and retrieval of receipts with visualization dashboards for business insights. Results demonstrate improved transaction efficiency, enhanced security, and significant reduction in paper usage, positioning this solution as a sustainable alternative to conventional receipts. Future directions include block chain integration for immutable storage and AI-driven sales analytics.

Keywords : Digital Receipts, Cloud Computing, Sustainable IT, Flask, AWS RDS, QR Code Payments, Analytics Dashboard.
