OEM Purchase Order Parsing, GST e-Invoicing & Intelligent Tender Chatbot
Automating Purchase Order (PO) to Sales Order (SO) conversion, national GST e-Invoicing/e-Way bill generation, and intelligent tender document assistance.
Operational Constraints & What Was in the Way
Legacy friction, system bottlenecks, and functional limits requiring custom engineering.
Operational & Engineering Context
An enterprise electronics OEM managing government tenders and corporate IT contracts processed hundreds of complex, multi-page PDF purchase orders weekly by hand.
Identified Friction Points
Manual entry of 50+ line-item purchase orders into enterprise ERP systems
created typographical errors and order delays
Strict national GST compliance
required error-free e-Invoice IRN and e-Way bill generation within tight delivery windows
Sales and bidding teams
spent hours scanning 200-page government tender documents for technical eligibility criteria
