E-Cell OC

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

  1. Smart Scanning – Snap a photo of any bill; OCR extracts details accurately.

  2. Automatic Categorisation – ML tags expenses (food, transport, utilities, shopping).

  3. Cross-App Integration – Syncs with UPI apps (GPay, PhonePe), food delivery, ride apps, and email receipts.

  4. Unified Dashboard – Displays monthly spend, recurring payments, and category breakdowns.

  5. Smart Reminders – Calendar alerts for bill due dates.

  6. 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

  • Problem
    bills are difficult for most to keep up with. Receipts get lost, deadlines are forgotten, and people do not realize how much they are spending. At tax time, people struggle to do the documentation, which leads to mistakes, missed deductions. The real problem is that there is no inexpensive and simple way to stay on top of it.
  • Gaps in Existing Market
    These requirements are not fulfilled by current solutions. Most of the apps out there are business oriented and contain too many complex features that normal users do not require. Some charge outrageous subscription fees, rendering them unusable by students, freelancers, and small households. Hiring an accountant is also beyond the budgets of most people. This leaves a clear vacuum for a tool that is simple, reliable, and lowcost.
  • Proposed Solution
    My idea is a smart finance app that will act as a personal financial aid assistant. It will be easy for the user to capture bills and receipts using the phone camera or by uploading them. OCR software within the app will scan the details such as amount, vendor, date, and tax. All the data will be stored securely in encrypted cloud storage and will be automatically organized in categories such as food, travel, utility, or education.
    The application will also generate neat reports that can be directly submitted for tax returns. It will remind users before all important due dates and suggest money saving tips depending on an individual's spending habits. At just one hundred and twenty five rupees per month, it is an easy solution for anyone wanting to manage expenses without agony or perplexity.
  • Who Benefits
    Effective financial management impacts us all, including students and freelancers, families and household budgets, and small business operators. Lack of organization causes undue stress, money loss, and financial savings opportunities lost. Such a tool gives its users the power to keep their money in check, lessens financial worry, and encourages improved financial behavior.
  • Why this Problem Matters for Me                                                                                                                                                                                                         Financial management is important because it affects everyone in their daily lives. I care about this issue because having a simple and affordable tool for staying organized can help people surround themselves with less stress, save money, and ultimately, make better financial decisions.
  • Technical Details
    The app utilizes optical character recognition to pull essential information from receipts and bills. All information is encrypted and held securely in the cloud. Expense categorization is done automatically, and AI algorithms may analyze spending habits to offer personalized advice. Reminders are controlled by integrated notifications, making the app functional and simple to use on any smartphone.
