Kitgenix PDF Invoicing for WooCommerce

Most WooCommerce stores eventually need proper order documents. You might need a PDF invoice for accounting, a receipt for the customer, a packing slip for fulfilment, or a credit note when a refund is issued. You also want those documents to look professional, match your branding, and be reliable across different WooCommerce email flows. Kitgenix PDF Invoicing for WooCommerce is a lightweight, security-first PDF invoicing plugin that generates WooCommerce order PDFs on demand — without creating heavy background jobs, and without storing piles of PDF files in your uploads folder. It’s built with real-world store requirements in mind: stable numbering, safe PDF rendering, theme-overridable templates, email attachments that clean up after themselves, and a clean admin workflow for previewing and downloading documents from the order screen. It is also designed to be modular and developer-friendly, so it can grow with your store and be customised safely. What this plugin generates This plugin can generate the following WooCommerce PDF documents: Invoice (PDF)\ Receipt (PDF)\ Packing Slip (PDF)\ Credit Note (PDF) (when refunds exist) Each document type is defined in a document registry and can be extended via filters, making it possible to add additional document types later without rewriting the core plugin. Why store owners choose Kitgenix PDF Invoicing It’s secure by default. PDF generation uses Dompdf configured with strict defaults. Remote fetching is disabled by default, and Dompdf is chrooted to allowed paths. PHP execution inside templates is disabled by default (opt-in only), and all public/admin actions are protected by capability checks and nonces. It doesn’t bloat your site. PDFs are generated only when needed. Email attachments are created as temporary files and cleaned up automatically. The plugin avoids unnecessary processing on normal page loads. It’s built for WooCommerce documents, not generic PDFs. Everything revolves around WooCommerce orders: document numbering, refund-aware credit notes, email attachments, and customer download links in the right places. It’s modular and extensible. The plugin boots a module set (Invoicing, Frontend, Admin, Email, Settings) and allows developers to alter module registration. Document types, templates, filenames, HTML output and availability can all be filtered. Features (in more detail)
