Build a sophisticated, futuristic web application called **InvoiceAI Portal**.

## Core Functionality

### 1. Invoice Upload Portal

- Users can drag & drop or upload PDF, DOCX, or image invoices.  

- Multiple file upload support with progress bar.  

- Clean, minimal dashboard with futuristic UI elements (glassmorphism, subtle gradients, rounded corners).  

### 2. AI Invoice Parsing

- Once uploaded, invoices are automatically sent to an AI model that extracts:  

  - Vendor name  

  - Invoice number  

  - Date  

  - Line items (description, quantity, price, subtotal)  

  - Taxes & totals  

- Display extracted data in a structured, editable table before submission.  

### 3. Database Integration

- Parsed invoice data is saved into a **cloud database** (e.g., Firebase, Supabase, or PostgreSQL).  

- Users can search, filter, and view past invoices.  

- Option to export data as CSV or Excel.  

### 4. User Authentication & Roles

- Secure login/signup with email + OAuth (Google, Microsoft).  

- Roles: Admin (full control), Accountant (view/edit), Viewer (read-only).  

### 5. Analytics Dashboard

- Summary of invoices processed this month, total spend, top vendors.  

- Charts/graphs for spending trends over time (use a charting library like Recharts or Chart.js).  

### 6. UI/UX Design

- Futuristic, sleek, and professional.  

- Dark mode + light mode toggle.  

- Smooth animations with Framer Motion.  

- Sidebar navigation (Upload, Invoices, Analytics, Settings).  

### 7. Additional Features

- Error handling & notifications (toast messages for success/failure).  

- Multi-language support.  

- Settings page for managing API keys, export options, and team members.  

- AI auto-categorization of invoices by expense type (e.g., utilities, marketing, payroll).  

## Tech Stack (Suggested)

- **Frontend:** React + TailwindCSS + shadcn/ui + Framer Motion  

- **Backend:** Node.js/Express or Next.js API routes  

- **Database:** Supabase or Firebase Firestore  

- **Authentication:** Firebase Auth or Auth0  

- **AI Parsing:** Connect to OpenAI/Gemini API for invoice text extraction and structuring

### Overall Goal

A **beautiful, modern, and futuristic invoice management app** where users can upload invoices, have them automatically parsed by AI, stored in a database, and viewed through a sleek dashboard with analytics and insights.
