Automate invoice processing with AI

This tutorial teaches how to automate invoice processing by extracting data from PDFs uploaded to Google Drive.

It uses n8n, a workflow automation tool, and Mistral OCR API, an AI-powered text extraction service, to pull invoice details, match fields, convert currencies to USD if needed, and log everything into a Google Sheet.

Professionals can save hours on repetitive financial tasks with this practical setup.

Key objectives

• Set up n8n to trigger when new invoice PDFs are uploaded to a Google Drive folder.
• Extract text from PDFs using Mistral’s OCR API.
• Convert non-USD amounts to USD.
• Append the invoice data to a Google Sheet automatically.
