WPC PDF Invoices And Packing Slips

WPC PDF Invoices And Packing Slips adds a document workflow to WooCommerce orders. It generates PDF invoices and packing slips, attaches them to selected customer emails, and places invoice access in the customer’s account history. The useful distinction is that it treats document presentation and numbering as configurable parts of the shop rather than fixed output.

Documents for each order

The plugin covers the two documents most shops need after checkout: an invoice for the customer and a packing slip for fulfilment. Both can be attached to standard WooCommerce emails, including messages associated with processing and completed orders. This keeps the documents alongside the existing order communication instead of requiring staff to create them separately.

Customers can also download invoices from their order history on the frontend. For the shop team, bulk actions in the order list create a ZIP archive containing multiple invoices or packing slips. That gives fulfilment staff a way to handle a group of orders without opening each order individually.

Templates and previews

Three built-in design directions are available for invoices and packing slips: minimalist, modern, and elegant. The more important feature for a customised shop is the template engine. Administrators can upload PHP templates to the theme’s wpcpi_templates/ folder and select them from the WordPress admin interface.

The preview system uses data from the latest order and opens the result in a new tab. It does not assign a new invoice number or save a temporary file during preview. That makes it suitable for checking a layout before it becomes part of the live document flow. The templates also expose do_action and apply_filters hooks, giving developers extension points for deeper changes than the built-in settings provide.

Numbering and shop details

Invoice numbering includes a configurable prefix, year, number, and suffix format. Sequential numbers can use zero-padding and reset on monthly or yearly cycles. Shops that need a recognisable numbering scheme therefore have control over both the appearance of the number and the point at which the sequence starts again.

Branding options cover the shop logo and tax or VAT details. The logo supports Base64 handling for PDF rendering. Invoice and packing slip documents have independent paper settings, with A4, Letter, and Legal sizes plus portrait or landscape orientation. That separation is useful when the customer-facing invoice and the warehouse-facing slip need different page layouts.

What to weigh

The customisation path is aimed at people comfortable with WordPress themes and PHP. A custom design is not created in a visual editor; it is uploaded as a PHP template in a particular theme folder. That gives developers control, but it puts layout work and template maintenance on the site owner or developer.

There is also a fair amount of configuration to settle before the documents are dependable: email attachment choices, numbering format, reset cycle, logo, tax details, paper size, and orientation. The preview uses the latest order as its data source, so checking unusual order data or every possible document variation requires deliberate review rather than relying on a single preview.

Who it suits

This is a good fit for a WooCommerce shop that needs invoices and packing slips to be part of its order process, rather than an occasional manual export. It suits stores that want several ready-made visual styles, customer self-service from the My Account area, and batch handling from the order list.

It is particularly relevant where invoice numbering rules, separate invoice and packing slip formats, or email-specific attachments matter. Developer access adds value because the hooks and PHP templates provide room for shop-specific document logic. Smaller shops with straightforward documents can use the built-in templates, while more particular stores have a defined route to branded layouts and custom output.
