NINJA Docsmith for WooCommerce gives your WooCommerce store professional, sequentially numbered PDF documents — entirely on your own server, with no cloud dependency.
Invoice PDF — contains your company logo, name, address and tax/VAT details; the customer’s billing address; a line-items table with unit prices, quantities, subtotals, shipping, tax, discounts and a bold total row; and the payment method. Every invoice receives a persistent sequential number (e.g. INV-00042) that is stored on the order so it never changes on regeneration.
Packing Slip PDF — a price-free pick/pack document showing the shipping address, item names, quantities, and the chosen shipping method. Ideal for warehouse staff.
Email attachment — choose which WooCommerce emails (Completed Order, Processing Order, Customer Invoice, New Order, or any other) should automatically include the invoice PDF as an attachment. The PDF is generated on the fly and attached before the email is sent.
Admin download & print — every order row gains two action links (“Invoice PDF” and “Packing Slip PDF”) that stream the document inline so you can view or print it directly from the browser. A bulk action (“Download Invoice PDFs”) lets you grab a ZIP of invoices for multiple selected orders at once.
Settings (under WooCommerce → PDF Invoices):
<ul>
<li>Company name, address, and tax/VAT/registration details printed in the document header</li>
<li>Optional logo — paste the URL of any JPEG or PNG from your media library</li>
<li>Invoice number prefix (e.g. “INV-“) and configurable starting number</li>
<li>Checkboxes for which WC email notifications should carry the invoice attachment</li>
</ul>
Compatibility — HPOS-safe (Custom Order Tables supported), tested on WordPress 6.8–7.0 and WooCommerce 8.0+. Requires PHP 7.4 or later.
Privacy — the plugin makes zero external requests during normal operation. PDF generation runs entirely on your server. The only optional network call is the consent-gated “NINJA Updates” subscription (see below).
<h4>Third-party library: FPDF</h4>
This plugin bundles FPDF 1.86 by Olivier PLATHEY (http://www.fpdf.org). FPDF is free software distributed under a permissive licence that permits free use for any purpose, commercial or not, with no attribution required. The library is included as a single PHP file (<code>includes/lib/fpdf.php</code>) with no Composer or external autoloader needed.
<h3>Stay updated (optional)</h3>
The settings screen has an optional “NINJA Updates” card: tick the consent box and enter your email to hear about plugin updates and new NINJA modules. Nothing is sent unless you submit that form. You can unsubscribe with one click at any time.
