Pinta PDF Invoice Module for PrestaShop

Core Functionality & Access Control

Instead of relying on rigid default layouts, this module provides an adaptable invoice system directly integrated with PrestaShop order data:

• Customizable Document Workflows: Allows merchants to generate, customize, download, and email branded PDF invoices tailored for customers, internal auditing, and tax compliance.
• Secure Customer Access: Enables shoppers to download PDF invoices directly from their order details page, fully protected by strict customer ownership checks and secure order keys.
• Automated Email Delivery: Automatically attaches generated PDF invoices to order status emails the moment an order hits a status configured for invoice creation.

Key Features & Templates

The module is packed with practical tools designed to give merchants complete control over document appearance and structure:

• Editable Layout Templates: Customize layout structures, text blocks, headers, footers, and product sections directly from the Back Office.
• Variable & Token Reference: Features a built-in variable list to easily map order details, customer data, and itemized totals into templates.
• Advanced Tax Layouts: Displays explicit VAT and tax summary tables utilizing dedicated layout placeholders.
• Multilingual & Non-Latin Font Support: Comes pre-bundled with translation files (English, Ukrainian, German, Spanish, French, Russian) and fallback typography to properly render Cyrillic and non-ASCII text.
• Visual Elements: Supports adding professional document features like custom text/image watermarks, barcodes, and QR codes.

Accounting & Compliance Architecture

Built to handle real-world accounting workflows cleanly without breaking historical store records:

• Legal Sequential Numbering: Offers optional, gap-free invoice and delivery slip numbering using highly configurable formats with padding adjustments and yearly resets.
• Persistent Document Numbers: Once a compliant legal number is assigned to a document, it is locked permanently. Regenerating the PDF reuses the exact same number to keep financial records flawless.
• Safe Backward Compatibility: Legal sequential numbering is turned off by default, ensuring existing historical invoices retain their original numbering formats unless explicitly changed.
