🧾 BillBuddy AI: A Privacy-First Invoice Assistant

Managing invoices manually can be time-consuming for freelancers and small businesses. I built BillBuddy AI, a local-first invoice assistant that helps extract invoice details and manage records in one place.

💡 What is BillBuddy AI?

BillBuddy AI is a prototype application designed to simplify invoice management while keeping document

nts and records local.

Users can upload an invoice, review AI-extracted details, and manage payment records through a simple interface.

✨ Features

• 📄 Upload PDF, PNG, JPG, WEBP, and TXT invoices
• 🤖 Extract invoice details using a locally running Ollama model
• ✏️ Review and verify extracted information before saving
• 🗄️ Store invoice records in a local SQLite database
• 📊 View invoice and payment summaries on a dashboard
• 💰 Manage payment statuses
• 📥 Export invoice records to CSV

🛠️ Tech Stack

• Python
• Streamlit
• Ollama (local LLM inference)
• SQLite
• Pandas

🔒 Privacy-First Approach

BillBuddy AI is designed to process documents using a locally running language model and store records in a local SQLite database. This reduces the need to send invoice documents to an external AI service.

AI-extracted information can be inaccurate, so users should verify all fields before saving or relying on them.

🚀 How to Run

1. Clone the repository.
2. Install the Python dependencies.
3. Install and start Ollama.
4. Download the model specified in the project setup.
5. Run the Streamlit application.

Check the README for the exact installation commands and model name.

🎯 What I Learned

Building BillBuddy AI helped me explore local LLM integration, document processing, structured data extraction, database operations, and building interactive applications with Streamlit.

This is a prototype, and I plan to improve its extraction accuracy, validation, and invoice management workflow further.

I'd love to hear your feedback and suggestions!

Note: BillBuddy AI is a prototype, not accounting or tax advice. Always verify invoice details manually.
