Automated Invoice Processing with AI-Powered OCR
detail.loadingPreview
Streamline your financial operations by automatically extracting key data from new invoices. This workflow monitors a Google Drive folder, uses AI-powered OCR to parse invoice details, and saves the structured information directly into a Google Sheet, eliminating manual data entry.
About This Workflow
This powerful n8n workflow revolutionizes how businesses handle incoming invoices. Say goodbye to manual data entry and tedious reconciliation. By connecting Google Drive, Google Sheets, and Mistral AI's advanced OCR capabilities, this template provides an end-to-end solution for intelligent invoice processing. It automatically detects new invoices in a designated Google Drive folder, performs Optical Character Recognition to extract critical information like invoice numbers, dates, amounts, and IBANs, and then neatly organizes this data into a Google Sheet. It even includes logic to prevent reprocessing already handled files, ensuring data integrity and efficiency. Ideal for finance teams, small businesses, and anyone looking to automate their accounts payable workflows.
Key Features
- Automated Invoice Intake: Automatically detects and processes new invoice files uploaded to a specific Google Drive folder.
- Intelligent AI-Powered OCR: Leverages Mistral AI to accurately extract structured data from various invoice formats.
- Duplicate Prevention: Intelligently filters out already processed invoices, preventing redundant entries in your spreadsheet.
- Structured Data Output: Organizes extracted invoice details into a clean, easy-to-read Google Sheet with predefined columns (Invoice No, Date, Amount, IBAN, etc.).
- Scalable & Customizable: Built on n8n, allowing for easy expansion and customization to fit unique business requirements.
How To Use
To set up and use this workflow, follow these steps:
- Google Drive Trigger: Configure the 'On new file in Google Drive' node. Connect your Google Drive account and specify the 'Invoices_Inbox' folder (or your desired folder ID) where you will upload new invoices.
- Google Sheets Setup: Link your Google Sheets account to the 'Get already processed rows from Sheets' and 'Save data to Google Sheets' nodes. Create a new Google Sheet (e.g., 'n8n_ocr_invoices') and ensure the first row contains headers matching the desired output columns (e.g., 'Id', 'Invoice No', 'Invoice date', 'Gross Amount incl. VAT', 'IBAN').
- Mistral AI Integration: For the 'Mistral Upload' node, you will need to set up a credential for Mistral AI. This typically involves an API key. Ensure the URL
https://api.mistral.ai/v1/filesandpurpose: "ocr"are correctly configured. - Connect Extraction Logic (Implicit): While not explicitly shown in this 'Lite' snippet, you would typically add a node (e.g., another HTTP Request to Mistral's chat endpoint, a Function, or a Code node) between 'Mistral Upload' and 'Save data to Google Sheets' to retrieve the OCR results, parse the relevant invoice fields, and format them for the Google Sheet. This is where the core invoice data extraction would occur based on the OCR output.
- Activate Workflow: Once all credentials are set and configurations are complete, activate the workflow. New files added to your Google Drive 'Invoices_Inbox' will now be automatically processed.
