The Problem Managing bills and expenses today is scattered and stressful. We get paper bills, PDFs, email invoices, and app notifications, often losing track of spending patterns. Existing apps either focus on banking or are too complex for everyday users. There’s a need for a single, simple system to track, organise, and understand all expenses from daily bills to subscriptions.
What GreenBill Does GreenBill is a mobile-first solution that uses OCR (Optical Character Recognition) and lightweight ML models to scan bills, extract key details (amount, date, category, merchant), and automatically log them. It goes beyond storage by acting as a personal financial assistant, connecting with apps we already use.
How it Works
Smart Scanning – Snap a photo of any bill; OCR extracts details accurately.
Automatic Categorisation – ML tags expenses (food, transport, utilities, shopping).
Cross-App Integration – Syncs with UPI apps (GPay, PhonePe), food delivery, ride apps, and email receipts.
Unified Dashboard – Displays monthly spend, recurring payments, and category breakdowns.
Smart Reminders – Calendar alerts for bill due dates.
Secure Cloud Storage – Backups via Google Drive/Dropbox.
Why GreenBill Matters Instead of juggling multiple apps, GreenBill gives users a single source of truth for spending. It’s useful for students, professionals, and families, helping them track, save, and plan effortlessly.
Future Vision
AI Insights – Personalised suggestions like “Reduce dining expenses by 20% next month.”
Smart Saving Goals – Set targets for gadgets, trips, or emergencies.
Shared Expenses – Split costs with friends/flatmates.
Green Impact Tracking – Track eco-friendly purchases to encourage sustainable spending.
Why I’m Building This As a student, I’ve struggled to manage personal expenses. Using my CS skills (OCR, APIs, ML), I can prototype GreenBill and test it with peers before scaling.
Next Steps
Prototype OCR + logging pipeline
Build a minimal Android app (Flutter/React Native)
Pilot with students for UX & accuracy feedback
