Case Study: AI-Powered Document Scanner & Fraud Detection System
A mid-sized finance and operations company handling high volumes of invoices, receipts, and vendor documents faced challenges in document validation, fraud detection, and manual processing delays.
Problem Statement :
The client was struggling with:
- Manual verification of invoices (time-consuming & error-prone)
- Fake or manipulated invoices slipping through
- Poor-quality scanned documents affecting data accuracy
- No automated system to flag suspicious transactions
- High operational cost due to manual checks
Solution Provided :
We developed a Custom AI-Based Document Processing System that combines:
The solution included:
- Auto-detects document edges
- Enhances low-quality scans
- Converts images into structured data
- Extracts key fields:
- Invoice Number
- Vendor Details
- Amount
- Date
- Works with multiple formats (PDF, images, scans)
AI model identifies suspicious patterns like:
- Blurry or low-quality documents
- Edited or tampered invoices
- Duplicate invoice numbers
- Unusual high transaction amounts
- Vendor mismatch or missing data
- Real-time alerts for flagged documents
- Risk score for each invoice
- Easy approval/rejection workflow
- Audit logs for compliance
Real-time notifications for appointment confirmations, reminders, and report availability.
A web-based admin system to manage users, bookings, reports, and operational workflows.
