Automate Receipt Categorization with AI | OpenAI + Telegram + n8n + Google Drive + Sheets
Description:
In this video, I walk through an end-to-end automation built in n8n that uses OpenAI's GPT-4o to analyze receipt images and categorize expenses as business or personal—automatically.
Here’s how it works:
💬 Snap a photo of your receipt and send it via Telegram.
🤖 The automation uses GPT-4o to extract key details like:
Total spent
Location
Date
Type of expense (business or personal)
Description of the spend
📁 The receipt image is uploaded to Google Drive, organized by year.
📊 The extracted data is appended to a Google Sheet for easy tracking and reporting.
📲 You’ll even receive a Telegram confirmation summarizing the entry.
🔍 Categorization rules are baked in:
Restaurants and gas stations → Business
Groceries and Costco → Personal
This workflow is perfect for freelancers, small business owners, or anyone looking to automate expense tracking and eliminate the manual effort of organizing receipts.
🚀 Built entirely using:
n8n for workflow automation
OpenAI GPT-4o for image understanding
Telegram as the front-end input
Google Drive for file storage
Google Sheets for expense logging
🔧 No-code meets AI in a practical, scalable solution for real-life tasks.
