Invoicing Plugin

Product Description:

The Sylius Invoicing Plugin provides automated invoice generation for Sylius-based eCommerce applications. It integrates directly with the order workflow to create invoices automatically when an order reaches a configured state.

Invoices are generated as PDF documents and stored as immutable records, ensuring compliance with accounting and auditing requirements. Both customers and administrators can easily access and download invoices from the storefront and admin interfaces.

Built using Symfony and Sylius best practices, the plugin is designed to be fully extensible, allowing developers to customize invoice generation logic, document templates, and storage configuration according to project requirements.

Automatic Invoice Generation

• Automatic Invoice Generation - Invoices are automatically created when an order reaches a configured state (by default when the order is created).
• Order Lifecycle Integration - The plugin listens to order and payment workflow transitions to trigger invoice generation.
  

PDF Invoice Documents

• PDF Invoice Creation - Generates standardized PDF invoices using wkhtmltopdf.
• Downloadable Documents - Invoice PDFs are accessible directly from both the Admin Panel and the customer account area.
• Customer Self-Service Access - Customers can download invoices from their orders list and order details pages.
  

Compliance and Data Integrity

• Immutable Invoice Records - Once generated, invoices remain unchanged, supporting accounting, legal, and audit requirements.
• Reliable Order Documentation - Each invoice is permanently linked to its corresponding order.

Extensibility and Configuration

• Customizable Storage - Configure where and how invoices are stored on the server.
• Extension Points - Extend invoice logic through Symfony services and events.
• Template Customization - Modify invoice layout and styling using Twig templates.

Additional Technical Information

The plugin integrates directly with the Sylius order lifecycle and automatically generates invoices based on configured workflow transitions.

When an order reaches the configured state:

1. The plugin triggers invoice generation.
2. A PDF invoice document is created.
3. The file is stored on the server.
4. The invoice is linked to the corresponding order.
5. Customers and administrators can download the invoice from their respective interfaces.
   

This architecture ensures a reliable, automated, and extensible invoicing workflow fully aligned with the Sylius ecosystem.
