Transform accounts payable from a manual bottleneck into an intelligent, automated system that reads invoices, detects fraud, and processes payments automatically—saving 20+ hours per week while preventing costly fraudulent payments.

🎯 What This Workflow Does

Automates the complete invoice-to-payment cycle with advanced AI:

1. 📧 Check Invoices from Jotform - Monitor Jotform for Invoice Submission
2. 🤖 AI-Powered OCR - Extracts ALL data from PDFs and images (vendor, amounts, line items, dates, tax)
3. 🚨 Fraud Detection Engine - Analyzes 15+ fraud patterns: duplicates, anomalies, suspicious vendors, document quality
4. 🚦 Intelligent Routing - Auto-routes based on AI risk assessment:
   • Critical Fraud (Risk 80-100): Block → Slack alert → CFO investigation
   • Manager Review (>$5K or Medium Risk): Approval workflow with full analysis
   • Auto-Approve (<$5K + Low Risk): Instant → QuickBooks → Vendor notification
5. 📊 Complete Audit Trail - Every decision logged to Google Sheets with AI reasoning
