Executive Summary

The Local Purchase Order (LPO) feature, branded as "EVA Docs", is a comprehensive document processing system that uses OCR (Optical Character Recognition) to automatically extract and process Local Purchase Orders from PDF and image files. The system converts physical LPO documents into structured digital data, matches products, applies pricing, and allows conversion to sales orders.
