Kodnexus AI Build Battle – Smart Invoice Challenge

About the Challenge: Can you turn a simple customer message into a professional invoice using AI? KODNEXUS AI BUILD BATTLE is a free, 180-minute online build sprint where participants create a working AI-powered invoice automation tool. Your application should understand a customer's requirement written in plain natural language, extract key details, fetch service pricing from a connected sheet/database, and generate a clean, review-ready invoice. Core Workflow to Build: Customer Requirement → AI Extraction → Price Lookup → Invoice Generation → Review/Approval Flow Eligibility & Guidelines: Participation: Individual participation only. Registration: Free. Build Time: 180 Minutes. AI Tools: AI assistants and coding copilots are fully allowed.
