+# Stripe Payment Integration - Multi-Tenant Ecommerce Platform
+
+## Architecture Overview
+
+The payment integration uses **Stripe Connect** to handle multi-vendor payments, enabling:
+- Each vendor to receive payments directly
+- Platform to collect fees/commissions
+- Proper financial isolation between vendors
+- Compliance with financial regulations
+
+## Payment Models

+
+## Updated Workflow Integration
+
+### Enhanced Customer Purchase Workflow
+
+```
+Customer adds products to cart
+    ↓
+Customer proceeds to checkout
+    ↓
+System creates Order (payment_status: pending)
+    ↓
+Frontend calls POST /api/v1/public/vendors/{vendor_id}/payments/create-intent
+    ↓
+PaymentService creates Stripe PaymentIntent with vendor destination
+    ↓
+Customer completes payment with Stripe Elements
+    ↓
+Stripe webhook confirms payment
+    ↓
+PaymentService updates Order (payment_status: paid, status: processing)
+    ↓
+Vendor receives order for fulfillment
+```
+
+### Payment Configuration Workflow
+
+```
+Vendor accesses payment settings
+    ↓
+POST /api/v1/vendor/payments/setup
+    ↓
+System creates Stripe Connect account
+    ↓
+Vendor completes Stripe onboarding
+    ↓
+Webhook updates account status to 'active'
+    ↓
+Vendor can now accept payments
+```
+
+This integration provides secure, compliant payment processing while maintaining vendor isolation and enabling proper revenue distribution between vendors and the platform.

+## 🎨 Frontend Architecture
+
+### Alpine.js Integration
+
+#### Why Alpine.js?
+
+- ✅ Lightweight (15KB) - perfect for multi-tenant platform
+- ✅ No build step required - works directly in HTML
+- ✅ Reactive state management - modern UX without complexity
+- ✅ Perfect Jinja2 integration - server + client harmony
+- ✅ Scoped components - natural vendor isolation
+
+#### Example: Product Detail Page
+
+```html
+<div x-data="productDetail()" x-init="loadProduct()">
+    <!-- Reactive product display -->
+    <h1 x-text="product?.title"></h1>
+    <p class="price">€<span x-text="product?.price"></span></p>
+    
+    <!-- Quantity selector with validation -->
+    <input 
+        type="number" 
+        x-model.number="quantity"
+        :min="product?.min_quantity"
+        :max="product?.available_inventory"
+    >
+    
+    <!-- Add to cart with loading state -->

+```
+
+## 🔒 Security Implementation
+
+### Authentication Flow
+
+**Admin Login:**
+```
+1. POST /api/v1/admin/auth/login
+2. Verify credentials + admin role
+3. Generate JWT token
+4. Store token in localStorage
+5. Include in Authorization header for protected routes
+```
+
+**Vendor Team Login:**
+```
+1. POST /api/v1/vendor/auth/login
+2. Detect vendor context (subdomain or path)
+3. Verify credentials + vendor membership
+4. Generate JWT token with vendor context
+5. All subsequent requests validated against vendor
+```
+
+**Customer Login:**
+```
+1. POST /api/v1/public/vendors/{id}/auth/login
+2. Verify customer credentials for specific vendor
+3. Generate JWT token with customer context
+4. Customer can only access their own data
+```
+
+### Vendor Context Detection
+
+```python
+# Automatic vendor detection from:
+1. Subdomain: vendor-a.platform.com
+2. Path parameter: /vendor/VENDOR_A/
+3. JWT token: Embedded vendor_id in claims
+
+# Complete data isolation:
+- All queries automatically scoped to vendor_id
+- Cross-vendor access prevented at service layer
+- Exception raised if vendor mismatch detected
+```
+
+### Exception Handling Pattern
+
+```python
+# Frontend-friendly error responses
+{
+    "detail": "Human-readable error message",
+    "error_code": "PRODUCT_NOT_FOUND",
+    "status_code": 404,
+    "timestamp": "2025-01-10T12:00:00Z",
+    "request_id": "abc123"
+}
+
+# Consistent error codes across platform
+- VENDOR_NOT_FOUND
+- PRODUCT_NOT_IN_CATALOG
+- INSUFFICIENT_INVENTORY
+- INVALID_ORDER_STATUS
+- UNAUTHORIZED_VENDOR_ACCESS
+```
+
+## 📊 Database Schema
+

+
+## Architecture Principles
+
+### Multi-Tenancy Model
+- **Complete Vendor Isolation**: Each vendor operates independently with no data sharing
+- **Chinese Wall**: Strict separation between vendor data and operations
+- **Self-Service**: Vendors manage their own teams, products, and marketplace integrations
+- **Scalable**: Single codebase serves all vendors with vendor-specific customization
+
+### Data Flow Architecture
+```
+Marketplace CSV → MarketplaceProduct (staging) → Product (catalog) → Order → Analytics
+                                 ↓
+                          Email Notifications → Audit Logs → Monitoring
+```
+
+### API Structure
+- **Admin APIs** (`/api/v1/admin/`): Platform-level administration
+- **Vendor APIs** (`/api/v1/vendor/`): Vendor-scoped operations (requires vendor context)
+- **Public APIs** (`/api/v1/public/vendors/{vendor_id}/`): Customer-facing operations
+- **Shared APIs** (`/api/v1/shared/`): Utility endpoints (health, webhooks)
+
+### Service Layer Architecture
+- **Domain Services**: Each service handles one business domain (products, orders, payments)
+- **Cross-Cutting Services**: Shared services (cache, audit, monitoring, notifications)
+- **Integration Services**: External service integration (payments, search, storage)
+
+### Frontend Architecture
+- **Static Assets**: All frontend files served from `/static/` directory
+- **Single Application**: One frontend codebase serving all vendors
+- **Context-Aware Routing**: Automatic vendor detection via subdomain or path
+- **Dynamic Theming**: Vendor-specific customization and branding
+- **Role-Based UI**: Permission-driven interface elements
+

+
+## Technology Integration
+
+### Database Layer
+- **PostgreSQL**: Primary database with ACID compliance

+# Multi-Tenant Ecommerce Platform - Vertical Slice Development Plan
+
+## Overview
+
+This document outlines a vertical slice development approach for the multi-tenant ecommerce platform. Each slice delivers a complete, working user workflow that validates core architectural decisions and provides immediate value.
+
+## Development Philosophy
+
+**Vertical Slice Benefits:**
+- Working software at each milestone
+- Early validation of architecture decisions
+- Immediate stakeholder feedback
+- Reduced risk through incremental delivery
+- Clear progress demonstration
+
+## Technology Stack Updates
+
+**Frontend Framework:** Alpine.js (v3.x)
+- Lightweight (15KB), no build step required
+- Perfect integration with Jinja2 templates
+- Reactive state management without complexity
+- CDN-based, works seamlessly with vanilla HTML/CSS/JS approach
+
+**Why Alpine.js:**
+- Minimal learning curve - feels like inline JavaScript
+- No conflicts with Jinja2 template syntax
+- Scoped reactivity - perfect for multi-tenant isolation
+- Progressive enhancement - works even if JS fails
+- Ideal for AJAX-heavy applications
+
+## Slice Development Order
+
+### Slice 1: Admin Creates Vendor → Vendor Owner Logs In (Week 1)
+**Core Value:** Establish multi-tenant foundation and vendor isolation
+
+**User Stories:**
+- ✅ As a Super Admin, I can create vendors through the admin interface
+- ✅ As a Super Admin, I can manage vendor accounts
+- ✅ As a Vendor Owner, I can log into my vendor-specific admin interface
+- ✅ The system correctly isolates vendor contexts
+
+**Technical Implementation:**
+
+#### Backend Components (Days 1-3) ✅
+```python
+# Essential Models
+class Vendor:
+    id, name, subdomain, owner_email, is_active, created_at, updated_at
+
+class User:
+    id, email, hashed_password, role, vendor_id, is_active, created_at, updated_at
+
+# Core Services

+# Multi-Tenant Ecommerce Platform - Complete Naming Convention Guide
+
+## Overview
+
+This document establishes consistent naming conventions across the entire multi-tenant ecommerce platform. Consistent naming improves code readability, reduces developer confusion, and ensures maintainable architecture.
+
+## Core Principles
+
+### 1. Context-Based Naming
+- **Collections/Endpoints**: Use PLURAL (handle multiple items)
+- **Entities/Models**: Use SINGULAR (represent individual items)
+- **Domains/Services**: Use SINGULAR (focus on one domain area)
+
+### 2. Terminology Standardization
+- Use **"inventory"** not "stock" (more business-friendly)
+- Use **"vendor"** not "shop" (multi-tenant architecture)
+- Use **"customer"** not "user" for end customers (clarity)
+
+### 3. File Naming Patterns
+- **API files**: `entities.py` (plural)
+- **Model files**: `entity.py` (singular)
+- **Service files**: `entity_service.py` (singular + service)
+- **Exception files**: `entity.py` (singular domain)
+
+## Detailed Naming Rules
+
+### API Endpoint Files (PLURAL)
+**Rule**: API files handle collections of resources, so use plural names.
+
+**Location**: `app/api/v1/*/`
+
+**Examples**:
+```
+app/api/v1/admin/
+├── vendors.py      # Handles multiple vendors
+├── users.py        # Handles multiple users
+└── dashboard.py    # Exception: not a resource collection
+
+app/api/v1/vendor/
+├── products.py     # Handles vendor's products
+├── orders.py       # Handles vendor's orders
+├── customers.py    # Handles vendor's customers
+├── teams.py        # Handles team members
+├── inventory.py    # Handles inventory items
+└── settings.py     # Exception: not a resource collection
+
+app/api/v1/public/vendors/
+├── products.py     # Public product catalog
+├── orders.py       # Order placement
+└── auth.py         # Exception: authentication service
+```
+
+**Rationale**: REST endpoints typically operate on collections (`GET /products`, `POST /orders`).
+
+### Database Model Files (SINGULAR)
+**Rule**: Model files represent individual entity definitions, so use singular names.
+
+**Location**: `models/database/`
+
+**Examples**:
+```
+models/database/
+├── user.py         # User, UserProfile classes
+├── vendor.py       # Vendor, VendorUser, Role classes
+├── customer.py     # Customer, CustomerAddress classes
+├── product.py      # Product, ProductVariant classes
+├── order.py        # Order, OrderItem classes
+├── inventory.py    # Inventory, InventoryMovement classes
+├── marketplace.py  # MarketplaceImportJob class
+└── admin.py        # Admin-specific models
+```
+
+**Class Names Within Files**:
+```python
+# models/database/product.py
+class Product(Base):           # Singular
+class ProductVariant(Base):    # Singular
+
+# models/database/inventory.py  
+class Inventory(Base):         # Singular
+class InventoryMovement(Base): # Singular
+```
+
+**Rationale**: Each model class represents a single entity instance in the database.
+
+### Schema/Pydantic Model Files (SINGULAR)
+**Rule**: Schema files define validation for individual entities, so use singular names.
+
+**Location**: `models/schema/`
+
+**Examples**:
+```
+models/schema/
+├── user.py         # UserCreate, UserResponse classes
+├── vendor.py       # VendorCreate, VendorResponse classes
+├── customer.py     # CustomerCreate, CustomerResponse classes
+├── product.py      # ProductCreate, ProductResponse classes
+├── order.py        # OrderCreate, OrderResponse classes
+├── inventory.py    # InventoryCreate, InventoryResponse classes
+├── marketplace.py  # MarketplaceImportRequest class
+└── admin.py        # Admin operation schemas
+```
+
+**Class Names Within Files**:
+```python
+# models/schema/product.py
+class ProductCreate(BaseModel):    # Singular entity
+class ProductUpdate(BaseModel):    # Singular entity
+class ProductResponse(BaseModel):  # Singular entity
+```
+
+**Rationale**: Schema models validate individual entity data structures.
+
+### Service Files (SINGULAR + "service")
+**Rule**: Service files handle business logic for one domain area, so use singular + "service".
+
+**Location**: `services/`
+
+**Examples**:
+```
+services/
+├── auth_service.py        # Authentication domain
+├── admin_service.py       # Admin operations domain
+├── vendor_service.py      # Vendor management domain
+├── customer_service.py    # Customer operations domain
+├── team_service.py        # Team management domain
+├── product_service.py     # Product operations domain
+├── order_service.py       # Order operations domain
+├── inventory_service.py   # Inventory operations domain
+├── marketplace_service.py # Marketplace integration domain
+└── stats_service.py       # Statistics domain
+```
+
+**Class Names Within Files**:
+```python
+# services/product_service.py
+class ProductService:      # Singular domain focus
+    def create_product()   # Operates on single product
+    def get_products()     # Can return multiple, but service is singular
+```
+
+**Rationale**: Each service focuses on one business domain area.
+
+### Exception Files (SINGULAR)
+**Rule**: Exception files handle errors for one domain area, so use singular names.
+
+**Location**: `app/exceptions/`
+
+**Examples**:
+```
+app/exceptions/
+├── base.py             # Base exception classes
+├── handler.py          # Exception handlers
+├── auth.py             # Authentication domain exceptions
+├── admin.py            # Admin domain exceptions
+├── vendor.py           # Vendor domain exceptions
+├── customer.py         # Customer domain exceptions
+├── product.py          # Product domain exceptions
+├── order.py            # Order domain exceptions
+├── inventory.py        # Inventory domain exceptions
+└── marketplace.py      # Marketplace domain exceptions
+```
+
+**Class Names Within Files**:
+```python
+# app/exceptions/product.py
+class ProductNotFoundException(ResourceNotFoundException):
+class ProductAlreadyExistsException(ConflictException):
+class ProductValidationException(ValidationException):
+```
+
+**Rationale**: Exception files are domain-focused, not collection-focused.
+
+### Middleware Files (DESCRIPTIVE)
+**Rule**: Middleware files use descriptive names based on their function.
+
+**Location**: `middleware/`
+
+**Examples**:
+```
+middleware/
+├── auth.py                 # Authentication middleware
+├── vendor_context.py       # Vendor context detection
+├── rate_limiter.py         # Rate limiting functionality
+├── logging_middleware.py   # Request logging
+└── decorators.py           # Cross-cutting decorators
+```
+
+**Rationale**: Middleware serves specific cross-cutting functions.
+
+### Frontend Files
+**Rule**: Frontend files use context-appropriate naming.
+
+**Location**: `frontend/`
+
+**Examples**:
+```
+frontend/
+├── admin/
+│   ├── vendors.html        # PLURAL - lists multiple vendors
+│   ├── users.html          # PLURAL - lists multiple users
+│   └── dashboard.html      # SINGULAR - one dashboard
+├── vendor/admin/
+│   ├── products.html       # PLURAL - lists multiple products
+│   ├── orders.html         # PLURAL - lists multiple orders
+│   ├── teams.html          # PLURAL - lists team members
+│   └── dashboard.html      # SINGULAR - one dashboard
+└── shop/
+    ├── products.html       # PLURAL - product catalog
+    ├── product.html        # SINGULAR - single product detail
+    ├── orders.html         # PLURAL - order history
+    └── cart.html           # SINGULAR - one shopping cart
+```
+
+**Rationale**: 
+- List views are plural (show collections)
+- Detail views are singular (show individual items)
+- Functional views use descriptive names
+
+## Terminology Standards
+
+### Core Business Terms
+
+| Use This | Not This | Context |
+|----------|----------|---------|
+| inventory | stock | All inventory management |
+| vendor | shop | Multi-tenant architecture |
+| customer | user | End customers (buyers) |
+| user | member | Platform/vendor team members |
+| team | staff | Vendor team members |
+| order | purchase | Customer orders |
+| product | item | Catalog products |
+
+### Database Naming
+
+**Table Names**: Use singular, lowercase with underscores
+```sql
+-- Correct
+inventory
+inventory_movements
+vendor_users
+
+-- Incorrect  
+inventories
+inventory_movement
+vendorusers
+```
+
+**Column Names**: Use singular, descriptive names
+```sql
+-- Correct
+vendor_id
+inventory_level
+created_at
+
+-- Incorrect
+vendors_id
+inventory_levels
+creation_time
+```
+
+### API Endpoint Patterns
+
+**Resource Collections**: Use plural nouns
+```
+GET    /api/v1/vendor/products      # List products
+POST   /api/v1/vendor/products      # Create product
+GET    /api/v1/vendor/orders        # List orders
+POST   /api/v1/vendor/orders        # Create order
+```
+
+**Individual Resources**: Use singular in URL structure
+```
+GET    /api/v1/vendor/products/{id}     # Get single product
+PUT    /api/v1/vendor/products/{id}     # Update single product
+DELETE /api/v1/vendor/products/{id}     # Delete single product
+```
+
+**Non-Resource Endpoints**: Use descriptive names
+```
+GET    /api/v1/vendor/dashboard/stats   # Dashboard statistics
+POST   /api/v1/vendor/auth/login        # Authentication
+GET    /api/v1/vendor/settings          # Vendor settings
+```
+
+## Variable and Function Naming
+
+### Function Names
+```python
+# Correct - verb + singular object
+def create_product()
+def get_customer()
+def update_order()
+def delete_inventory_item()
+
+# Correct - verb + plural when operating on collections
+def get_products()
+def list_customers()
+def bulk_update_orders()
+
+# Incorrect
+def create_products()     # Creates one product
+def get_customers()       # Gets one customer
+```
+
+### Variable Names
+```python
+# Correct - context-appropriate singular/plural
+product = get_product(id)
+products = get_products()
+customer_list = get_all_customers()
+inventory_count = len(inventory_items)
+
+# Incorrect
+products = get_product(id)    # Single item, should be singular
+product = get_products()      # Multiple items, should be plural
+```
+
+### Class Attributes
+```python
+# Correct - descriptive and consistent
+class Vendor:
+    id: int
+    name: str
+    subdomain: str
+    owner_user_id: int        # Singular reference
+    created_at: datetime
+
+class Customer:
+    vendor_id: int            # Belongs to one vendor
+    total_orders: int         # Aggregate count
+    last_order_date: datetime # Most recent
+```
+

+```
+
+### Enable/Disable Button

+errorMessage.classList.remove('show');
+```
+
+---
+
+## 🔧 CSS Variables Usage
+
+### In CSS
+```css
+.custom-button {
+    background: var(--primary-color);
+    padding: var(--spacing-md);
+    border-radius: var(--radius-lg);
+    color: white;
+}
+```
+
+### In JavaScript
+```javascript
+// Get value
+const primaryColor = getComputedStyle(document.documentElement)
+    .getPropertyValue('--primary-color');
+
+// Set value
+document.documentElement.style
+    .setProperty('--primary-color', '#ff0000');
+```
+
+---
+
+## 🎨 Brand Customization
+
+### Quick Brand Color Change
+Edit `static/css/shared/base.css`:
+```css
+:root {
+    --primary-color: #YOUR_COLOR;
+    --primary-dark: #DARKER_SHADE;
+}
+```
+
+### Per-Vendor Theming
+Create `static/css/vendor/themes/VENDOR_CODE.css`:
+```css
+:root {
+    --primary-color: #VENDOR_COLOR;
+}
+```
+
+Load in HTML:
+```html
+<link rel="stylesheet" href="/static/css/vendor/themes/techstore.css">
+```
+
+---
+
+## ⚡ Performance Tips
+
+### CSS Loading
+```html
+<!-- Preload critical CSS -->
+<link rel="preload" href="/static/css/shared/base.css" as="style">
+<link rel="stylesheet" href="/static/css/shared/base.css">
+```
+
+### Minimize Repaints
+```css
+/* Use transform instead of position changes */
+.animate {
+    transform: translateY(-4px);
+    transition: transform 0.2s;
+}
+```
+
+---
+
+## 🐛 Common Issues
+
+### Issue: Styles not applying
+**Solution**: Check CSS is loaded in correct order (base.css first)
+
+### Issue: Button not clickable
+**Solution**: Check z-index and pointer-events
+
+### Issue: Layout breaks on mobile
+**Solution**: Add viewport meta tag:
+```html
+<meta name="viewport" content="width=device-width, initial-scale=1.0">
+```
+
+### Issue: Colors look wrong
+**Solution**: Ensure base.css is loaded (contains CSS variables)

+    --radius-lg: 8px;   /* Large radius */
+    --radius-xl: 12px;  /* Extra large */
+}
+```
+
+### Adding Vendor-Specific Themes
+
+Create a new file: `static/css/vendor/themes/{vendor_code}.css`
+
+```css
+/* static/css/vendor/themes/techstore.css */
+:root {
+    --primary-color: #ff6b6b;
+    --primary-dark: #ee5a52;
+}
+
+.vendor-header {
+    background: linear-gradient(135deg, var(--primary-color), var(--primary-dark));
+    color: white;
+}
+```
+
+Then in vendor pages:
+```html
+<link rel="stylesheet" href="/static/css/vendor/themes/techstore.css">
+```
+
+---
+
+## 📱 Responsive Breakpoints
+
+All CSS files include responsive styles:
+
+```css
+/* Desktop: Default styles */
+
+/* Tablet */
+@media (max-width: 1024px) {
+    /* Tablet-specific styles */
+}
+
+/* Mobile */
+@media (max-width: 768px) {
+    /* Mobile-specific styles */
+}
+
+/* Small Mobile */
+@media (max-width: 480px) {
+    /* Small mobile-specific styles */
+}
+```
+
+---
+
+## 🖨️ Print Styles
+
+All CSS files include print-friendly styles that:
+- Hide navigation and action buttons
+- Remove shadows and backgrounds
+- Optimize for black & white printing
+- Adjust layout for paper
+
+---
+
+## ✅ Installation Checklist
+
+- [ ] Create `static/css/shared/` directory
+- [ ] Create `static/css/admin/` directory
+- [ ] Create `static/css/vendor/` directory
+- [ ] Copy `base.css` to `static/css/shared/`
+- [ ] Copy `auth.css` to `static/css/shared/`
+- [ ] Copy `admin.css` to `static/css/admin/`
+- [ ] Copy `vendor.css` to `static/css/vendor/`
+- [ ] Update all HTML files with correct `<link>` tags
+- [ ] Test pages load with styles
+- [ ] Test responsive design (resize browser)
+- [ ] Test in multiple browsers
+
+---
+
+## 🔍 Troubleshooting
+
+### Styles Not Loading
+
+**Check**:
+1. File paths are correct in HTML `<link>` tags
+2. FastAPI is serving static files: `app.mount("/static", StaticFiles(directory="static"), name="static")`
+3. Browser cache - try hard refresh (Ctrl+F5)
+4. Browser console for 404 errors
+
+### Styles Look Wrong
+
+**Check**:
+1. CSS files are in correct order (base.css first)
+2. No conflicting inline styles in HTML
+3. Browser DevTools to inspect element styles
+4. CSS variables are defined in `:root`
+
+### Mobile Layout Broken
+
+**Check**:
+1. Viewport meta tag in HTML: `<meta name="viewport" content="width=device-width, initial-scale=1.0">`
+2. Responsive classes are applied
+3. Test in actual devices, not just browser resize
+
+---
+
+## 📚 Additional Resources
+
+### CSS Best Practices
+- Always use CSS variables for colors and spacing
+- Prefer utility classes over custom CSS
+- Keep specificity low
+- Use BEM naming for custom components
+- Comment complex CSS rules
+
+### Performance Tips
+- Minimize CSS files for production
+- Use CSS variables instead of repetitive values
+- Avoid deeply nested selectors
+- Use `will-change` sparingly
+- Combine similar media queries
+
+---
+
+## 🎉 You're All Set!
+
+Your CSS structure is now complete and production-ready. The styles are:
+- ✅ Modular and maintainable
+- ✅ Responsive across all devices
+- ✅ Consistent with design system
+- ✅ Performance optimized
+- ✅ Easy to customize
+- ✅ Print-friendly
+
+**Next Steps**:
+1. Copy all CSS files to your project
+2. Update HTML files with correct links
+3. Test in browser
+4. Customize brand colors
+5. Deploy!

+
+## 📦 Prerequisites Checklist
+
+Before starting, ensure you have:
+
+```bash
+# Check Python version (need 3.11+)
+python --version
+
+# Check PostgreSQL is running
+psql --version
+
+# Check you have the project files

+```
+
+## ⚡ 5-Step Setup
+
+### Step 1: Install Dependencies (2 minutes)
+
+```bash
+# Create virtual environment
+python -m venv venv
+
+# Activate it
+source venv/bin/activate  # macOS/Linux
+# OR
+venv\Scripts\activate  # Windows
+
+# Install requirements
+pip install fastapi uvicorn sqlalchemy psycopg2-binary python-jose passlib bcrypt python-multipart
+```
+
+### Step 2: Configure Database (3 minutes)
+
+```bash
+# Create .env file
+cat > .env << 'EOF'
+# Database
+DATABASE_URL=postgresql://postgres:postgres@localhost:5432/multitenant_ecommerce
+
+# JWT Security
+JWT_SECRET_KEY=your-super-secret-key-change-this-in-production-please
+JWT_EXPIRE_MINUTES=30
+
+# Server
+SERVER_ADDRESS=http://localhost:8000
+DEBUG=True
+PROJECT_NAME=Multi-Tenant Ecommerce Platform
+ALLOWED_HOSTS=["*"]
+EOF
+
+# Create database
+createdb multitenant_ecommerce
+
+# Or using psql:
+# psql -U postgres -c "CREATE DATABASE multitenant_ecommerce;"
+```
+
+### Step 3: Initialize Database (3 minutes)
+
+Create `scripts/init_db.py`:
+
+```python
+# scripts/init_db.py
+import sys
+sys.path.append('.')
+
+from app.core.database import Base, engine
+from models.database.user import User
+from models.database.vendor import Vendor, Role, VendorUser
+from middleware.auth import AuthManager
+
+def init_database():
+    """Initialize database with tables and admin user"""
+    
+    print("🔧 Creating database tables...")
+    Base.metadata.create_all(bind=engine)
+    print("✅ Tables created successfully")
+    
+    # Create admin user
+    from sqlalchemy.orm import Session
+    db = Session(bind=engine)
+    
+    try:
+        admin = db.query(User).filter(User.username == "admin").first()
+        
+        if not admin:
+            auth_manager = AuthManager()
+            admin = User(
+                email="admin@platform.com",
+                username="admin",
+                hashed_password=auth_manager.hash_password("admin123"),
+                role="admin",
+                is_active=True
+            )
+            db.add(admin)
+            db.commit()
+            print("\n✅ Admin user created:")
+            print("   📧 Email: admin@platform.com")
+            print("   👤 Username: admin")
+            print("   🔑 Password: admin123")
+        else:
+            print("\nℹ️  Admin user already exists")
+        
+        print("\n🎉 Database initialization complete!")
+        print("\n🚀 Next steps:")
+        print("   1. Run: uvicorn main:app --reload")
+        print("   2. Visit: http://localhost:8000/static/admin/login.html")
+        
+    finally:
+        db.close()
+
+if __name__ == "__main__":
+    init_database()
+```
+
+Run it:
+
+```bash
+python scripts/init_db.py
+```
+
+### Step 4: Create Directory Structure (2 minutes)
+
+```bash
+# Create required directories
+mkdir -p static/admin
+mkdir -p static/vendor
+mkdir -p static/js/shared
+mkdir -p static/css/admin
+mkdir -p static/css/shared
+```
+
+Copy the HTML/JS files I created into these directories:
+- `static/admin/login.html`
+- `static/admin/dashboard.html`
+- `static/admin/vendors.html`
+- `static/vendor/login.html`
+- `static/vendor/dashboard.html`
+- `static/js/shared/api-client.js`
+
+### Step 5: Start the Application (1 minute)
+
+```bash
+# Start FastAPI server
+uvicorn main:app --reload --port 8000
+```
+
+You should see:
+```
+INFO:     Uvicorn running on http://127.0.0.1:8000
+INFO:     Application startup complete.
+```
+
+## 🧪 Test the Complete Flow (5 minutes)
+
+### Test 1: Admin Login
+
+1. **Open browser**: http://localhost:8000/static/admin/login.html
+2. **Login**:
+   - Username: `admin`
+   - Password: `admin123`
+3. **Expected**: Redirected to admin dashboard
+
+### Test 2: Create Vendor
+
+1. **Click**: "Create New Vendor" button
+2. **Fill form**:
+   ```
+   Vendor Code: TECHSTORE
+   Name: Tech Store Luxembourg
+   Subdomain: techstore
+   Owner Email: owner@techstore.com
+   (Leave other fields optional)
+   ```
+3. **Submit**: Click "Create Vendor"
+4. **Expected**: Success message with credentials displayed
+
+### Test 3: Copy Vendor Credentials
+
+**IMPORTANT**: Copy these credentials immediately (they're shown only once):
+
+```
+Vendor Code: TECHSTORE
+Subdomain: techstore
+Owner Username: techstore_owner
+Owner Email: owner@techstore.com
+Temporary Password: [COPY THIS!]
+```
+
+### Test 4: Vendor Login (Path-based)
+
+1. **Open new tab**: http://localhost:8000/vendor/techstore/login
+2. **Login**:
+   - Username: `techstore_owner`
+   - Password: [paste the temporary password]
+3. **Expected**: Redirected to vendor dashboard
+4. **Verify**: Dashboard shows "TECHSTORE Dashboard"
+
+### Test 5: Verify Isolation
+
+1. **Try accessing different vendor**: http://localhost:8000/vendor/otherstore/login
+2. **Expected**: "Vendor Not Found" message
+3. **Database check**:
+   ```sql
+   SELECT * FROM vendors WHERE vendor_code = 'TECHSTORE';
+   SELECT * FROM users WHERE email = 'owner@techstore.com';
+   ```
+
+## ✅ Success Indicators
+
+You know Slice 1 is working when:
+
+- [x] Admin can login and see dashboard
+- [x] Admin can create vendors
+- [x] Vendor owner credentials are generated
+- [x] Vendor owner can login
+- [x] Vendor dashboard shows correct vendor context
+- [x] Invalid vendor URLs show error message
+- [x] Each vendor is completely isolated
+
+## 🐛 Common Issues & Fixes
+
+### Issue: "Module not found" errors
+
+**Fix**:
+```bash
+pip install -r requirements.txt
+# Or install missing packages individually
+pip install fastapi sqlalchemy psycopg2-binary
+```
+
+### Issue: Database connection fails
+
+**Fix**:
+```bash
+# Check PostgreSQL is running
+sudo service postgresql status
+
+# Check database exists
+psql -U postgres -l | grep multitenant
+
+# Update DATABASE_URL in .env to match your setup
+```
+
+### Issue: "401 Unauthorized" in browser console
+
+**Fix**:
+```javascript
+// Open browser console (F12)
+// Check token exists:
+localStorage.getItem('admin_token')
+
+// If null, login again
+// If exists but still fails, token might be expired - login again
+```
+
+### Issue: Admin login redirects to login page
+
+**Fix**:
+```bash
+# Check admin user exists in database:
+psql -U postgres -d multitenant_ecommerce -c "SELECT * FROM users WHERE role='admin';"
+
+# If no results, run:
+python scripts/init_db.py
+```
+
+### Issue: Vendor context not detected
+
+**Fix**:
+Check URL format:
+- ✅ Correct: `localhost:8000/vendor/techstore/login`
+- ❌ Wrong: `localhost:8000/techstore/login`
+- ❌ Wrong: `localhost:8000/vendor/login`
+
+### Issue: Static files not loading (404)
+
+**Fix**:
+```python
+# Verify main.py has static file mounting:
+from fastapi.staticfiles import StaticFiles
+
+app.mount("/static", StaticFiles(directory="static"), name="static")
+```
+
+## 📊 Database Verification
+
+Check everything was created correctly:
+
+```sql
+-- Connect to database
+psql -U postgres -d multitenant_ecommerce
+
+-- Check tables
+\dt
+
+-- Check admin user
+SELECT id, username, email, role FROM users WHERE role = 'admin';
+
+-- Check created vendor
+SELECT id, vendor_code, name, subdomain, is_active, is_verified 
+FROM vendors;
+
+-- Check vendor owner
+SELECT id, username, email, role 
+FROM users WHERE email LIKE '%techstore%';
+
+-- Check default roles were created
+SELECT id, name, vendor_id 
+FROM roles 
+WHERE vendor_id = (SELECT id FROM vendors WHERE vendor_code = 'TECHSTORE');
+```
+
+Expected results:
+- 1 admin user
+- 1 vendor (TECHSTORE)
+- 1 vendor owner user
+- 4 roles (Owner, Manager, Editor, Viewer)
+
+## 🎯 Next Steps
+
+Once Slice 1 is working:
+
+### Option 1: Create More Vendors
+
+Test multi-tenancy by creating multiple vendors:
+1. Create `FASHIONSTORE` vendor
+2. Create `BOOKSHOP` vendor
+3. Verify each has isolated login and dashboard
+
+### Option 2: Proceed to Slice 2
+
+Move on to **Slice 2: Marketplace Product Import**:
+- Implement CSV import functionality
+- Create MarketplaceProduct staging table
+- Build import UI
+- Add Celery for background processing
+
+### Option 3: Customize UI
+
+Enhance the frontend:
+- Add custom CSS themes
+- Improve dashboard widgets
+- Add vendor statistics
+- Build team management UI

+    owner_email: 'owner@myshop.com'
+  })
+})
+.then(r => r.json())
+.then(d => console.log('Vendor created!', d));
+```
+
+## 🔒 Security Notes
+
+### For Development
+
+Current setup uses:
+- ✅ JWT tokens with bcrypt password hashing
+- ✅ HttpOnly would be recommended for production cookies
+- ✅ CORS middleware configured
+- ⚠️ Default admin password (change immediately!)
+- ⚠️ DEBUG=True (disable in production)
+
+### For Production
+
+Before going live:
+
+1. **Change default credentials**:
+   ```sql
+   UPDATE users SET hashed_password = 'new_hash' WHERE username = 'admin';
+   ```
+
+2. **Update environment variables**:
+   ```bash
+   DEBUG=False
+   JWT_SECRET_KEY=[generate strong random key]
+   ALLOWED_HOSTS=["yourdomain.com"]
+   ```
+
+3. **Enable HTTPS**:
+   - Use nginx/apache with SSL certificates
+   - Force HTTPS redirects
+   - Set secure cookie flags
+
+4. **Set up subdomain routing**:
+   - Configure DNS wildcards: `*.platform.com`
+   - Update nginx to route subdomains
+   - Test subdomain detection

+
+## 📋 Prerequisites
+
+Before implementing Slice 1, ensure you have:
+
+- ✅ PostgreSQL database running
+- ✅ Python 3.11+ with FastAPI
+- ✅ All dependencies installed (`pip install -r requirements.txt`)
+- ✅ `.env` file configured with database URL and JWT secret
+
+## 🚀 Implementation Steps
+
+### Step 1: Update Database Models
+
+Ensure your `models/database/vendor.py` includes:
+
+```python
+class Vendor(Base, TimestampMixin):
+    __tablename__ = "vendors"
+    
+    id = Column(Integer, primary_key=True, index=True)
+    vendor_code = Column(String, unique=True, nullable=False, index=True)
+    subdomain = Column(String(100), unique=True, nullable=False, index=True)
+    name = Column(String, nullable=False)
+    description = Column(Text)
+    owner_user_id = Column(Integer, ForeignKey("users.id"), nullable=False)
+    
+    # Business information
+    business_email = Column(String)
+    business_phone = Column(String)
+    contact_email = Column(String)
+    contact_phone = Column(String)
+    website = Column(String)
+    business_address = Column(Text)
+    tax_number = Column(String)
+    
+    # Status flags
+    is_active = Column(Boolean, default=True)
+    is_verified = Column(Boolean, default=False)
+    verified_at = Column(DateTime, nullable=True)
+    
+    # Theme and configuration
+    theme_config = Column(JSON, default=dict)
+    
+    # CSV URLs for marketplace integration
+    letzshop_csv_url_fr = Column(String)
+    letzshop_csv_url_en = Column(String)
+    letzshop_csv_url_de = Column(String)
+    
+    # Relationships
+    owner = relationship("User", back_populates="owned_vendors")
+```
+
+### Step 2: Create Database Migration
+
+Create a new Alembic migration:
+
+```bash
+# Generate migration
+alembic revision --autogenerate -m "Add vendor and role tables for slice 1"
+
+# Review the generated migration file
+# Then apply it:
+alembic upgrade head
+```
+
+### Step 3: Create Default Admin User
+
+Run the script to create initial admin:
+
+```python
+# scripts/create_admin.py
+from sqlalchemy.orm import Session
+from app.core.database import SessionLocal
+from middleware.auth import AuthManager
+from models.database.user import User
+
+def create_admin():
+    db = SessionLocal()
+    auth_manager = AuthManager()
+    
+    # Check if admin exists
+    admin = db.query(User).filter(User.username == "admin").first()
+    
+    if not admin:
+        admin = User(
+            email="admin@platform.com",
+            username="admin",
+            hashed_password=auth_manager.hash_password("admin123"),
+            role="admin",
+            is_active=True
+        )
+        db.add(admin)
+        db.commit()
+        print("✅ Admin user created:")
+        print("   Username: admin")
+        print("   Password: admin123")
+        print("   Email: admin@platform.com")
+    else:
+        print("ℹ️  Admin user already exists")
+    
+    db.close()
+
+if __name__ == "__main__":
+    create_admin()
+```
+
+Run it:
+```bash
+python scripts/create_admin.py
+```
+
+### Step 4: Deploy Frontend Files
+
+Ensure the following structure exists:
+
+```
+static/
+├── admin/
+│   ├── login.html
+│   ├── dashboard.html
+│   └── vendors.html
+├── js/
+│   └── shared/
+│       └── api-client.js
+└── css/
+    ├── shared/
+    │   └── base.css
+    └── admin/
+        └── admin.css
+```
+
+### Step 5: Update API Router
+
+Ensure `app/api/main.py` includes admin routes:
+
+```python
+from app.api.v1 import admin
+
+api_router.include_router(
+    admin.router,
+    prefix="/admin",
+    tags=["admin"]
+)
+```
+
+### Step 6: Start the Application
+
+```bash
+# Start the server
+uvicorn main:app --reload --port 8000
+
+# Or with hot reload
+python main.py
+```
+
+### Step 7: Test the Flow
+
+#### 7.1 Admin Login
+1. Navigate to `http://localhost:8000/static/admin/login.html`
+2. Login with:
+   - Username: `admin`
+   - Password: `admin123`
+3. Should redirect to dashboard
+
+#### 7.2 Create Vendor
+1. Click "Create New Vendor" button
+2. Fill in the form:
+   - Vendor Code: `TECHSTORE`
+   - Name: `Tech Store Luxembourg`
+   - Subdomain: `techstore`
+   - Owner Email: `owner@techstore.com`
+3. Submit the form
+4. **Save the displayed credentials!**
+
+#### 7.3 Verify Vendor Creation
+1. Check database:
+```sql
+SELECT * FROM vendors WHERE vendor_code = 'TECHSTORE';
+SELECT * FROM users WHERE email = 'owner@techstore.com';
+SELECT * FROM roles WHERE vendor_id = (SELECT id FROM vendors WHERE vendor_code = 'TECHSTORE');
+```
+
+2. Check admin dashboard - vendor should appear in "Recent Vendors"
+
+## 🧪 Testing Checklist
+
+### Admin Interface Tests
+- [ ] Admin can login with correct credentials
+- [ ] Admin login rejects non-admin users
+- [ ] Dashboard displays vendor statistics
+- [ ] Dashboard displays user statistics
+- [ ] Recent vendors list shows newest vendors
+- [ ] Vendor creation form validates inputs
+- [ ] Vendor code is auto-uppercased
+- [ ] Subdomain is auto-lowercased
+- [ ] Duplicate vendor code is rejected
+- [ ] Duplicate subdomain is rejected
+- [ ] Generated credentials are displayed once
+- [ ] Admin can view all vendors
+- [ ] Admin can verify/unverify vendors
+- [ ] Admin can activate/deactivate vendors
+
+### Vendor Context Tests
+- [ ] Subdomain detection works: `vendor.localhost:8000`
+- [ ] Path detection works: `localhost:8000/vendor/vendorname/`
+- [ ] Admin routes are excluded from vendor context
+- [ ] API routes are excluded from vendor context
+- [ ] Invalid vendor returns 404
+
+### Database Tests
+- [ ] Vendor record created correctly
+- [ ] Owner user record created
+- [ ] Owner has correct relationship to vendor
+- [ ] Default roles created (Owner, Manager, Editor, Viewer)
+- [ ] Vendor is auto-verified when created by admin
+- [ ] Timestamps are set correctly
+
+## 🔐 Security Considerations
+
+1. **Password Security**
+   - Temporary passwords are 12+ characters
+   - Include letters, numbers, and symbols
+   - Hashed with bcrypt before storage
+   - Displayed only once
+
+2. **Admin Access Control**
+   - JWT token required for all admin endpoints
+   - Role validation on every request
+   - Token expiration enforced
+
+3. **Vendor Isolation**
+   - Vendor context middleware enforces boundaries
+   - All queries filtered by vendor_id
+   - Cross-vendor access prevented
+
+## 📝 Configuration
+
+### Environment Variables
+
+```bash
+# Database
+DATABASE_URL=postgresql://user:pass@localhost:5432/dbname
+
+# JWT
+JWT_SECRET_KEY=your-secret-key-change-in-production
+JWT_EXPIRE_MINUTES=30
+
+# Server
+SERVER_ADDRESS=http://localhost:8000
+DEBUG=True
+
+# Platform
+PROJECT_NAME="Multi-Tenant Ecommerce Platform"
+ALLOWED_HOSTS=["*"]
+```
+
+### Development vs Production
+
+**Development Mode** (path-based):
+```
+http://localhost:8000/vendor/techstore/
+http://localhost:8000/admin/
+```
+
+**Production Mode** (subdomain-based):
+```
+https://techstore.platform.com/
+https://admin.platform.com/
+```
+
+## 🐛 Troubleshooting
+
+### Issue: Admin login fails
+**Solution**: Check that admin user exists and role is "admin"
+```python
+python scripts/create_admin.py
+```
+
+### Issue: Vendor creation returns 401
+**Solution**: Check that JWT token is valid and not expired
+```javascript
+// In browser console
+localStorage.getItem('admin_token')
+```
+
+### Issue: Vendor context not detected
+**Solution**: Check middleware is registered in `main.py`:
+```python
+app.middleware("http")(vendor_context_middleware)
+```
+
+### Issue: Database foreign key error
+**Solution**: Run migrations in correct order:
+```bash
+alembic upgrade head
+```
+
+## 📊 Success Metrics
+
+Slice 1 is complete when:
+
+- [x] Admin can log into admin interface
+- [x] Admin can create new vendors
+- [x] System generates vendor owner credentials
+- [x] Vendor owner can log into vendor-specific interface
+- [x] Vendor context detection works in dev and production modes
+- [x] Database properly isolates vendor data
+- [x] All tests pass
+- [x] Documentation is complete
+
+## 🎯 Next Steps - Slice 2
+
+Once Slice 1 is complete and tested, proceed to **Slice 2: Vendor Imports Products from Letzshop**:
+
+1. Implement marketplace CSV import
+2. Create MarketplaceProduct staging table
+3. Build product import UI
+4. Add background job processing with Celery
+5. Create import job monitoring
+
+## 💡 Tips
+
+1. **Always test in order**: Admin login → Vendor creation → Context detection
+2. **Save credentials immediately**: Password is shown only once
+3. **Use browser dev tools**: Check console for API errors
+4. **Check database directly**: Verify data is created correctly
+5. **Test both detection modes**: Path-based (dev) and subdomain (prod)

+
+SELECT v.vendor_code, u.username, u.email
+FROM vendors v
+JOIN users u ON v.owner_user_id = u.id
+ORDER BY v.id;
+```
+
+**Expected**:
+- [ ] Each vendor has unique owner
+- [ ] No shared users between vendors
+- [ ] Owner relationships are correct
+
+---
+
+## 4️⃣ Security Tests

+```
+
+- [ ] Passwords are hashed (not plain text)
+- [ ] Hashes start with "$2b$" (bcrypt)
+- [ ] Each hash is unique
+
+### JWT Token Validation
+
+```javascript
