🛡️ Auto-Audit Pro

Batch Financial Compliance Engine built with Python & Streamlit

Auto-Audit Pro automates the auditing of financial documents. It ingests PDF invoices, extracts structured data using OCR, and runs them against configurable business logic (e.g., "Flag transactions > $500" or "Detect Blacklisted Vendors").

🚀 Key Features

• Batch Processing: Upload 50+ invoices simultaneously for bulk auditing.
• Risk Scoring Algorithm: Automatically assigns "Low," "Medium," or "High" risk scores based on value and vendor reputation.
• Regex Pattern Matching: Detects currency values with or without symbols (e.g., $500 or 500 USD).
• Interactive Dashboard: View real-time metrics (Total Value Audited, Flagged Invoices).
• Data Export: Download a structured CSV report for further analysis in Excel.

🛠️ Tech Stack

• Core: Python 3.10+
• Frontend: Streamlit
• Data Extraction: pdfplumber, RegEx
• Data Handling: Pandas
