The Invoice workflow automates how we handle customer invoices. Whenever a new invoice email arrives, the system checks the attachment type, reads its content using OCR or PDF text extraction, then parses important details like invoice number, due date, and amount. These details are saved automatically into our Google Sheet and the file is stored in Google Drive. Finally, an email reminder is sent to the customer confirming their invoice and due date — all without any manual effort.
🧾 Invoice Workflow Summary
Goal: Automatically read invoices from Gmail, extract key details, save them to Google Sheets and Drive, and notify the customer.
Step 1 – Email Trigger
- The workflow starts when a new email with an invoice attachment arrives in Gmail.
- Supports both PDF and Image (JPG) files.
Step 2 – Text Extraction
- If it’s a PDF, text is read directly.

Step 4 – Storage
- Adds the extracted data to Google Sheets for tracking.
- Saves the invoice file to Google Drive (named by date).
