### Overview

Our client was struggling with time-consuming manual document processing and filing. Their accountants had to spend hours reviewing and entering information from invoices and other logistics documents. This led to increased costs and some errors that were missed. Our key challenge in this project was to develop a scalable OCR system capable of extracting relevant data minimizing human intervention. We had to train the solution on multiple unique invoice templates to ensure the OCR tool is able to process any information easily.

### Solution

- **Automated Invoice Recognition:** Developed an OCR-based system to extract key data points from invoices, including invoice number and date.
- **Document Classification:** Implemented an AI-powered classifier to categorize various document types such as invoices and CMRs.
- **Error Detection & Correction:** Integrated an anomaly detection system to identify errors and inconsistencies in scanned documents.
- **Seal Identification:** Leveraged Computer Vision (CV) technology to recognize and validate document seals.
- **Automated Document Registration:** Streamlined the upload and processing of recognized documents with minimal user intervention.
- **UI Integration:** Designed a user-friendly interface to enable seamless document management.
- **Scalability:** Ensured the system adapts to new invoice formats with minimal reconfiguration.

- **+200%** boost document processing speed
- **-20%** work hours reduction a year
- **-50%** cut paperwork processing time

### Technology Stack

- **Programming Language:** Python
- **Machine Learning Frameworks:** Pytorch, CatBoost, scikit-learn
- **OCR Tools:** Tesseract, Google Vision API
- **Computer Vision:** OpenCV
