Neutrope Japanese Invoice PDFs for WooCommerce

"Neutrope Japanese Invoice PDFs for WooCommerce" is a free plugin that generates Japanese-style invoice PDFs from your WooCommerce orders. It is designed for shops that need to deliver Japanese business documents (invoices and similar receipts) alongside their WooCommerce store.

Features (Free version)

• Invoice PDF generation (title, billing recipient block, line items, totals, consumption tax summary)
• One-click PDF output from the admin Order edit screen
• Customer-side invoice download from My Account (can be toggled on/off)
• Company name, address, and logo configurable from the settings screen
• High-Performance Order Storage (HPOS) compatible
• Japanese-language PDF output powered by mPDF
• Template (templates/invoice.php) can be overridden from your theme

Planned roadmap (no committed timeline)

The following items are being considered for a future paid version. They are not implemented in the free version and there is no guarantee they will ship.

• Qualified invoice number (Japan invoice system)
• Per-tax-rate display (10% / 8% reduced rate)
• Receipt document
• Bank transfer information
• Payment due date
• Company seal, header note, recipient honorific

The free plugin exposes filters and hooks so the items above can be added by add-on plugins without modifying the core.

Credits / Third-Party Licenses

This plugin bundles the following third-party software and fonts.

• mPDF — GPL-2.0-or-later. The PDF rendering engine. https://mpdf.github.io/
• Noto Sans JP — SIL Open Font License 1.1. Used for the Japanese text in the invoice PDF. Full license text is bundled at assets/fonts/OFL.txt. https://fonts.google.com/noto IPA fonts were not adopted because they are not GPL-compatible; OFL Noto Sans JP is used so the bundle stays GPL-compatible.
• DejaVu Sans Condensed — Bitstream Vera Fonts License / Public Domain. Four files (DejaVuSansCondensed.ttf / -Bold / -Oblique / -BoldOblique) are bundled because mPDF requires them as the internal sans-serif fallback. Full license text is bundled at assets/fonts/DejaVu-LICENSE.txt. https://dejavu-fonts.github.io/
