PDF Invoices & Packing Slips for WooCommerce

Quick take

This PDF invoice plugin solves a narrow but important WooCommerce operations problem: turning WooCommerce orders into printable and emailable business documents without manually creating them outside WordPress. The free plugin already covers the core WooCommerce invoice and WooCommerce packing slips workflow, while paid extensions expand document types, templates, exports, and other advanced requirements.

My PDF Invoices & Packing Slips review is strongest for stores that need consistent order documents generated from WooCommerce data. I would not treat it as a complete accounting system. It creates commerce documents, but bookkeeping, tax filing, and jurisdiction-specific compliance still need the appropriate accounting process around them.

Best fit: PDF Invoices & Packing Slips for WooCommerce makes the most sense for WooCommerce stores that need automated PDF invoices, packing slips, email attachments, and printable fulfillment documents. I would look elsewhere for businesses looking for a complete accounting system or jurisdiction-specific bookkeeping and tax-compliance platform.

What the free plugin handles

The core plugin generates PDF invoices and WooCommerce packing slips from orders. As a PDF invoice plugin, it uses the WooCommerce invoice data already stored with each order. Store owners can attach invoice documents to WooCommerce emails, download or print documents from order management, and configure document details such as numbering, dates, shop information, and templates.

This removes a repetitive manual step from fulfillment. Instead of copying order data into a separate document for every sale, the invoice and packing slip are generated from the order record that WooCommerce already maintains.

Features that matter in day-to-day order handling

Automatic invoice attachment

The plugin can attach PDF invoices to selected WooCommerce order emails. Recent releases also added logging around whether an attachment succeeded or failed, which is useful when a customer says an expected invoice did not arrive.

Invoice numbering and document control

Invoice numbering, dates, shop details, and document settings are managed independently from the WooCommerce order number. That is important for stores that need a consistent document sequence rather than simply printing the raw order ID.

Packing slips for fulfillment

Packing slips can be generated and printed from the same order workflow. For a small fulfillment team, having customer, address, and order-line information in one printable document is often more useful than opening each WooCommerce order during packing.

Bulk document workflows

The plugin supports bulk generation and printing from WooCommerce order management. This matters when fulfillment happens in batches rather than one order at a time.

E-document development in the current free plugin

The recent 5.x releases include substantial work around UBL, CII, EDI, VAT identifiers, and Peppol-related document handling. Version 5.16.1 is tested with WordPress 7.1, and 5.16.0 confirmed compatibility with WooCommerce 11.0.

Extensions for more specialized document requirements

WP Overnight offers paid extensions and bundles for requirements beyond the core workflow, including additional document types and premium templates. Premium Templates provide a drag-and-drop document customizer, while the Professional extension adds more advanced document functionality.

Free vs paid extensions

The free plugin is a sensible stopping point when the requirement is straightforward: generate invoices and packing slips, attach invoices to WooCommerce emails, and print or download documents from order management.

Paid extensions make more sense when you need additional document types, more advanced invoice behavior, visual template customization, or specialized integrations. I would decide this based on a specific missing document requirement instead of upgrading simply because the store has grown.

Where the trade-offs show up

The biggest trade-off is scope. A PDF invoice can look official without being the complete accounting record your business or tax authority requires. Store owners still need to confirm numbering, tax information, retention, e-invoicing, and bookkeeping requirements for their jurisdiction.

The second trade-off is extension complexity. The free core is focused, but advanced document types, premium templates, cloud destinations, or other specialized needs can involve separate extensions. That modular model is useful when you need only one extra capability, but it also means the final stack can be more than one plugin.

There is also a compatibility consideration around WooCommerce checkout and document data. Custom order fields and third-party plugins may need specific support before their data appears exactly where you expect in a document template.

PDF Invoices & Packing Slips pricing

Pricing checked September 9, 2026. The core PDF Invoices & Packing Slips for WooCommerce plugin is free on WordPress.org. That keeps PDF invoice pricing at zero for the basic document workflow. WP Overnight sells Professional, Premium Templates, and other extensions, including bundle options, but the current accessible public product text does not expose one stable bundle amount that I can verify.

For PDF invoice pricing, I would start with the free plugin and pay only when a required document type, template workflow, or integration is missing. That keeps a straightforward invoice-and-packing-slip setup from becoming unnecessarily complex.

PluginSuggest verdict

My WooCommerce invoice review conclusion is that the free plugin covers the practical invoicing and fulfillment needs of many WooCommerce stores without turning document generation into a separate system.

I would shortlist it when the goal is automated WooCommerce documents with room to extend later. I would choose dedicated accounting or e-invoicing software when the real requirement is financial compliance and bookkeeping rather than order-document generation.
