Overview
Overview This workflow automates invoice handling from upload to reporting using AI. Users submit invoices through a simple form. The workflow extracts key details, validates the data, stores valid invoices, and sends email notifications. It also generates a weekly summary report automatically. This helps reduce manual data entry and ensures consistent invoice processing. How It Works Form Submission Users upload an invoice (PDF or image) along with their email. Initial Storage The raw submission is stored for tracking and reference. Text Extraction The uploaded file is processed to extract text content. AI Data Extraction AI converts the raw text into structured invoice data such as invoice number, vendor, date, currency, and totals. Validation The workflow checks: Date format (YYYY-MM-DD) Allowed currencies Total amount validity Conditional Flow If valid → invoice is stored and a success email is sent If invalid → an error email is sent with details Weekly Reporting A scheduled trigger runs weekly to: Fetch all validated invoices Generate a summary report using AI Send the report via email Setup Instructions Add your OpenAI credentials (used for data extraction and reporting) Connect Gmail credentials for sending emails Configure Data Tables: invoice_form_submissions validated_invoices Update the Workflow Configuration node: Set report recipient email Adjust allowed currencies if needed Ensure the file field (invoiceFile) is correctly mapped Test with a sample invoice Activate the workflow Use Cases Automating invoice processing for small businesses Reducing manual accounting data entry Validating invoices before storing them Generating weekly financial summaries Handling invoice submissions from clients or teams Requirements OpenAI API credentials Gmail account (for sending emails) n8n Data Tables (or replace with your preferred database) n8n instance with file upload support Notes Make sure to fix the IF condition: Use {{$json.validation.isValid}} instead of accessing isValid directly.
