## Description
“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
* Shipping lines, WooCommerce order fee lines, and refunds reflected in the invoice
PDF totals
* Sales Summary screen (WooCommerce > 売上サマリー): aggregates orders directly
from order data — no dependency on WooCommerce Analytics caches — with date range,
order status and payment method filters, aggregation by order date / paid date/
completed date, refund-aware net totals, an order list, and UTF-8 (BOM) CSV export
* 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/

## Installation
#### Server requirements
* PHP 7.4 or later
* PHP extensions **mbstring** and **gd** (required by the bundled mPDF library)
* WooCommerce 7.0 or later, active
#### Steps
1. Upload the plugin ZIP and activate it. The distribution ZIP already bundles the
PDF library and the Japanese font, so `composer install` is not required.
2. Confirm that WooCommerce is active.
3. Open **WooCommerce > Japanese Invoice PDFs** and fill in your company name, address,
and logo.
4. Open any order from the admin and click the invoice button in the “Japanese Invoice
PDFs” meta box.
For developers: the distribution ZIP excludes `vendor/mpdf/mpdf/ttfonts` via `.distignore`.
If you run the plugin from source, run `composer install` first. The distribution
ZIP can be rebuilt locally with `powershell -File bin/build-zip.ps1`. CI builds
the same ZIP via GitHub Actions.
## FAQ
### Is WooCommerce required?
Yes. The plugin shows an admin notice and disables itself when WooCommerce is not
active.
### Can other people download my invoices?
No. Downloads from My Account require login, ownership of the order is enforced,
and a nonce is verified.
### Are PDFs stored on the server?
No. Every PDF is generated on demand and streamed to the browser, so there are no
leftover files that could be linked directly.
### Japanese characters look like garbled text
The plugin bundles Noto Sans JP (OFL 1.1), so no extra setup is needed. If you still
see broken characters, verify that the PHP `mbstring` and `gd` extensions are enabled
on your server.
### Amounts display with decimals like “¥2,400.00”
The plugin follows the WooCommerce currency settings. To hide decimals for JPY,
set **WooCommerce > Settings > General > Number of decimals** to 0.
### Recipient name order and the “Japan” suffix in the address
Name order, honorifics (sama, onchu, etc.) and country labelling are roadmap items.
The free version uses WooCommerce default formatting.
### Can I customize the template?
Yes. Copy `templates/invoice.php` to `wp-content/themes//neutrope-japanese-
invoice-pdfs-for-woocommerce/invoice.php` to override it.

## Change Log
#### 1.1.4
* Add: show a contextual Upgrade to Pro link on the Plugins screen when the Pro
add-on is not active. The link points to the live purchase page and includes
product-specific campaign attribution. No data, settings, or front-end behavior
changes.
#### 1.1.3
* Fix: sort Sales Summary order rows by the selected aggregation basis date in
ascending order, so the on-screen list and CSV export are easier to transfer
into spreadsheet-based sales management sheets.
#### 1.1.2
* Fix: show WooCommerce order fee line items (for example, cash-on-delivery fees)
in the invoice PDF item table. Fee amounts were already included in the order
subtotal/total; they are now itemized by the WooCommerce fee name so the visible
line items reconcile with the subtotal.
#### 1.1.1
* Add: completed date as a Sales Summary aggregation basis. Shops that mark orders
completed when shipped can use completed date as a shipping-date report, while
the existing default order-date behavior remains unchanged.
* Add: completed date to the Sales Summary order list and CSV export.
* Dev: expose the `wcjbp_sales_summary_date_bases` filter for safe date-basis label
customization. Query keys remain limited to order date, paid date and completed
date.
#### 1.1.0
* Add: Sales Summary screen under WooCommerce > 売上サマリー. Aggregates orders
directly from WooCommerce order data (HPOS compatible) without relying on WooCommerce
Analytics caches. Filter by date range, order status (default: processing / completed),
payment method, and aggregation basis date (order date or paid date). Summary
cards (order count, gross/refunded/net totals, goods, shipping, tax, average)
use the same refund-aware net logic as the invoice PDF. Includes an order list
and a UTF-8 BOM CSV export (capability- and nonce-checked). A safety cap limits
aggregation to 2000 orders and shows a warning when exceeded.
#### 1.0.2
* Fix: account for refunds in invoice PDF totals. Refunded orders now show refund
line(s) (負の金額) in the item table and compute the subtotal, tax, and total
from the net (post-refund) amounts, so the PDF matches WooCommerce’s refunded
totals. Handles product, shipping, and manual refunds, tax and tax-free, and
multiple refunds. Orders without refunds are unchanged.
#### 1.0.1
* Fix: include shipping lines in the invoice PDF. Orders with a shipping cost now
show a “送料（配送方法名）” row in the item table so the itemized rows reconcile
with the subtotal and total. Zero-cost shipping is not shown; multiple shipping
lines are supported.
#### 1.0.0
* Initial release (free MVP).
* Invoice PDF generation, admin output, My Account download, settings screen, HPOS
compatible.
