Receipt Processing for Small Businesses: Telegram Bot + Mindee

This workflow automates expense tracking by processing receipt images sent via Telegram, eliminating manual data entry. It uses OCR technology to extract data, validates inputs, and logs expenses to Google Sheets. Key nodes include Telegram Trigger for image capture, HTTP Request for Mindee API OCR, Set for data structuring, Google Sheets for logging, and Telegram for user notifications. It saves 8-10 hours weekly for finance teams or freelancers (1-15 members) managing 50+ receipts monthly, ideal for small businesses or consultants needing efficient, real-time expense tracking with robust error handling. Saves 8-10 hours weekly on 50+ monthly receipts. Suits small businesses or freelancers (1-50 employees). Requires Telegram (free), Mindee (~$29/month), Google Sheets (free), n8n (~$20/month). Scalable to 500 receipts/month, limited by API quotas. Install n8n via cloud.n8n.io. Create a Telegram bot via BotFather for API token (t.me/BotFather). Get Mindee API key from mindee.com (Account > API Keys). Set up Google Sheets OAuth2 via Google Cloud Console (APIs & Services > Credentials). Configure Telegram Trigger webhook (e.g., https://your-n8n-instance/webhook/ef81fe75-10c8-40c3-8bea-d65648556705). Set Google Sheets node with document ID. Test with a sample receipt image (JPG/PNG/PDF). Handle errors: invalid API keys—regenerate in platforms; low OCR confidence—prompt clearer images. Activate workflow in n8n. Monitor Google Sheets for data accuracy. Optimize by adjusting confidence thresholds or retry settings.", "businessValue": "Saves 8-10 hours/week on 50+ monthly receipts", "setupTime": "45-60 minutes", "difficulty": "Intermediate", "requirements": [ "Telegram (free), Mindee (~$29/month), Google Sheets (free), n8n (~$20/month)", "Telegram, Mindee, Google Sheets OAuth2 API keys", "Basic knowledge of Telegram bots and OCR integration" ], "useCase": "Automating receipt processing via Telegram"
