# Demo Session Service
## Overview
The **Demo Session Service** creates ephemeral, isolated demo environments for sales demonstrations and prospect trials. It provisions temporary tenants with pre-seeded realistic bakery data, allowing prospects to explore the full platform without affecting production data. Demo sessions automatically expire after a configurable period (default: 24 hours) and are completely isolated from real customer tenants, making it safe for prospects to experiment freely.
## Key Features
### Demo Environment Provisioning
- **One-Click Demo Creation** - Create demo tenant in seconds
- **Pre-Seeded Data** - Realistic sales, inventory, forecast data
- **Isolated Tenants** - Complete separation from production
- **Temporary Credentials** - Auto-generated demo user accounts
- **Configurable Duration** - 1 hour to 7 days (default: 24 hours)
- **Instant Access** - No email verification required
### Realistic Demo Data
- **90 Days Sales History** - Realistic transaction patterns
- **Product Catalog** - 20+ common bakery products
- **Inventory** - Current stock levels and movements
- **Forecasts** - Pre-generated 7-day forecasts

- **Suppliers** - 5+ sample supplier profiles
- **Team Members** - Sample staff with different roles
### Demo Scenarios
- **Standard Bakery** - Small neighborhood bakery (1 location)
- **Multi-Location** - Bakery chain (3 locations)
- **High-Volume** - Large production bakery
- **Custom Scenario** - Configurable for specific prospects
- **Spanish Locale** - Madrid-based bakery examples
- **Feature Showcase** - Highlight specific capabilities
### Session Management
