💡 Inspiration

Freelancers spend too much time fighting with Word templates and generic PDF generators. We wanted to build a tool that feels like a dedicated financial assistant—one that understands context, manages client details automatically, and produces professional results without the headache. We injected a "Tambo" personality to make the mundane task of invoicing actually engaging.

⚙️ What it does

• Conversational Invoicing: Users simply tell the AI "Create an invoice for $500 for the website redesign," and the system structures the data instantly.
• Context Awareness: The AI remembers client details, past items, and preferred terms, reducing data entry by 90%.
• Multi-Org Support: Users can seamlessly switch between different business identities (e.g., "Freelance Design" vs. "Consulting").
• Smart PDF Generation: We moved away from basic HTML prints to high-fidelity, printable invoices that look 100% professional.

🏗️ How we built it

• Frontend: Built with Next.js 15 (App Router) for server-side rendering and speed.
• AI Engine: Powered by Tambo AI, utilizing its TamboTool and TamboComponent architecture to give the Large Language Model direct control over our UI and state.
• State Management: Complex form state is handled via React Context and synchronized with the AI through custom events.
• Database: Supabase (PostgreSQL) handles relational data for users, organizations, invoices, and items.
• Styling: Tailwind CSS ensures a cohesive, responsive design system.

🧠 Challenges we ran into

• AI-State Synchronization: Ensuring the AI could read the current state of a complex invoice form (items, taxes, discounts) in real-time required a robust bi-directional event system.
• PDF Consistency: distinct challenges in ensuring the web view matched the printed output exactly across different browsers.

🚀 What's next for InvoiceAI

• Stripe Integration: Allowing "Pay Now" links directly on the invoices.
• Expense Tracking: Using the same AI interface to scan and categorize receipts.
• Mobile App: Bringing the chat-first invoicing experience to iOS.

📦 Features
