🎯 Problem Statement

Small businesses in Pakistan spend hours manually creating invoices, leading to delayed payments and errors.

🛠️ What I Built

A Flask web app where users upload purchase orders and the AI auto-generates a GST-compliant invoice PDF. Includes client database, recurring invoices, and payment reminders.

🔥 Challenges I Faced

Parsing inconsistent PDF formats from different vendors and handling Urdu text in line items.

💡 What I Learned

PDF text extraction with PyMuPDF, prompt engineering for structured JSON output, and Stripe-style responsive invoice templates.

🚀 Future Improvements

Multi-currency support, WhatsApp delivery of invoices, and OCR for scanned POs.

Loved the PDF parsing approach. Would love to see multi-currency next.
