## Key Features

EC-CUBE is purpose-built for Japanese e-commerce and includes features that most global platforms lack or require paid add-ons for:

- **Japanese Tax System**: Full support for Japan's reduced tax rate (軽減税率), consumption tax display (tax-inclusive/exclusive pricing), and tax rounding rules
- **Point System**: Built-in customer point rewards system with configurable point rates
- **Multiple Shipping**: Native support for sending an order to multiple shipping addresses (複数配送)
- **Customer Membership**: Customer registration, login, order history, and favorites
- **Product Classes**: Matrix-style product variations (e.g., size × color) with per-variation pricing and stock
- **Delivery Management**: Flexible delivery fee calculation by region and shipping method
- **Payment Integration**: Pluggable payment gateway architecture
- **PDF Generation**: Built-in order PDF / delivery slip generation via TCPDF
- **Two-Factor Authentication**: TOTP-based 2FA for admin accounts
- **Mail Templates**: Twig-based customizable email templates
- **CSV Import/Export**: Bulk product, order, and customer data management

## Customization

### Plugin System

EC-CUBE has a powerful plugin architecture. Plugins can:

- Add new entities and database tables
- Add or override controllers, forms, templates, and services
- Hook into the event system to modify behavior at any point
- Be installed/uninstalled/enabled/disabled from the admin panel
- Be distributed via the [EC-CUBE Owners Store](https://www.ec-cube.net/owners/)

### Event System

The Symfony EventDispatcher-based event system allows hooking into:

- Template rendering events (inject HTML/JS into pages)
- Controller events (modify request/response)
- Entity lifecycle events (Doctrine events)
- Order processing events (PurchaseFlow)

### PurchaseFlow

PurchaseFlow is EC-CUBE's pipeline-based order processing engine:

- **Validators**: Check stock availability, sale limits, payment totals
- **Preprocessors**: Calculate delivery fees, payment charges, point usage
- **Processors**: Reduce stock, update customer purchase info, generate order numbers
- **Discount Processors**: Apply coupon and campaign discounts

Each step in the pipeline can be customized or replaced via DI configuration.

### app/Customize Directory

Project-specific customizations go in `app/Customize/` without modifying core files:

- `app/Customize/Controller/` — Custom controllers
- `app/Customize/Entity/` — Entity extensions (via Doctrine trait)

- `app/Customize/Repository/` — Custom repositories
- `app/Customize/Service/` — Custom services
