WooCommerce PDF Invoices & Packing Slips

WooCommerce PDF Invoices & Packing Slips is the most widely used extension in the WooCommerce ecosystem for the automatic generation of commercial documentation in PDF format. Developed by WP Overnight, this professional solution allows online stores of any size to issue invoices, packing slips, credit notes, proforma invoices, and delivery notes directly from each order, without the need for manual processes or external tools.

The extension is designed for WooCommerce store owners who need to automate their sales documentation, as well as for warehouse and logistics teams that require standardized packing slips to streamline order packing and shipping. It is also especially useful for accounting and tax compliance departments, as it allows maintaining configurable sequential invoice numbering with prefixes, suffixes, and markers such as order ID or date.

Among its main features, it highlights the automatic generation of PDF invoices attached to order confirmation emails, the ability for customers to download their invoices from the My Account page, and the bulk export of documents in ZIP format from the admin panel. The Pro version adds advanced features such as automatic credit notes when processing refunds, proforma invoices, delivery notes, gap-free sequential numbering that complies with European tax regulations, and customizable templates with the brand's logo and colors.

Customization is one of its strengths: it allows uploading the store logo, configuring tax data such as IVA or VAT, choosing from multiple template styles, and adjusting the numbering format to meet the requirements of any local tax authority. Additionally, it is fully compatible with WooCommerce High Performance Order Storage (HPOS) and the new block-based checkout, ensuring its operation on the most recent versions of the platform.

For multilingual stores, the extension offers full support with WPML and Polylang, allowing each customer to receive their documents in their language. It also includes options to show or hide free items, disable invoices for orders with no cost, and configure custom paper sizes. With more than 300,000 active installations, this is the reference solution for any WooCommerce store looking to professionalize its sales documentation and optimize its invoicing and shipping processes.
