PDF Invoices & Packing Slips Pro for WooCommerce

Key Features

Auto-attaches the PDF invoice to WooCommerce order emails by hooking into the woocommerce_email_attachments filter for the order statuses you choose (processing, completed, or a custom status)

Generates four document types from one engine — invoice, packing slip, credit note and proforma invoice — each with its own independently styled template

Branded template builder in wp-admin: upload logo, set company address, VAT/GST/Tax ID, payment terms, footers and inject custom CSS without editing code

Sequential, gap-free invoice numbering with configurable prefix, suffix, zero-padding and yearly reset (e.g. INV-2026-00042), stored independently from WooCommerce order IDs

HPOS / custom-order-tables compatible — all order reads and writes go through the WooCommerce CRUD API (wc_get_orders, $order->get_meta) so it works on legacy and high-performance order storage

Documents stored as a dedicated custom post type with metadata, so each invoice is permanently archived and re-printable even after the order is edited

Bulk generate, print, merge-to-single-PDF and CSV/ZIP export from the WooCommerce Orders list via custom row actions and bulk actions

WooCommerce REST API endpoint to fetch any order's invoice or packing slip PDF programmatically for ERP, 3PL or accounting integrations

Customer 'Download invoice' button added to the My Account order view and order-confirmation emails via the woocommerce_order_details_after_order_table hook

WPML / Polylang and WordPress multisite ready — invoices render in the customer's order language with localized labels and number formats

Configurable tax display: line-level and summary tax, multiple tax classes, reverse-charge / zero-rated notes and per-country tax-ID labels

Attachment generation runs on WooCommerce's async email queue / WP-Cron so large bulk runs and high-volume stores never block checkout

Optional document storage to a protected uploads directory or S3-compatible bucket, with .htaccess / signed-URL protection so PDFs are not publicly guessable

Hookable architecture — every document exposes WordPress filters (e.g. for line items, totals, headers and footers) so future custom fields can be added without forking

About this Product

PDF Invoices & Packing Slips Pro for WooCommerce turns every WooCommerce order into a complete, compliant document set without anyone touching wp-admin. The moment an order reaches a status you choose (processing, completed, or a custom status), the plugin hooks into the relevant woocommerce_email_* action and attaches a branded PDF invoice directly to the customer's order email — no separate portal login, no manual export.

This is not an instant marketplace download. ECOSIRE custom-builds this plugin for your specific WooCommerce store, installs it on your WordPress site, and supports it afterward. We tailor it to your tax setup, your statuses, your gateways and your fulfilment workflow, then hand over a clean, namespaced plugin that lives in wp-content/plugins/ and survives WooCommerce and WordPress core updates.

Out of the box for your build, you get PDF invoices, packing slips, credit notes and proforma invoices, each with its own template and its own sequential numbering scheme with custom prefixes, suffixes and padding (for example INV-2026-00042). Documents are generated server-side, stored as a custom post type with metadata, and are fully HPOS-compatible — we read and write order data through WooCommerce's CRUD layer ($order->get_meta() / wc_get_orders()), so the plugin works whether your store uses the legacy post-based orders or the new high-performance custom order tables.

You also get a branded template builder: logo, company details, VAT/GST/Tax ID, footer terms, custom CSS, and per-document layouts you can edit from a dedicated wp-admin settings screen. Staff can bulk generate, print, merge and export documents straight from the Orders list via row and bulk actions, and a WooCommerce REST API endpoint lets your other systems pull a given order's PDF on demand. WPML/Polylang and WordPress multisite are supported on request, so documents render in each customer's language.

Numbering scheme configured to your accounting requirements (prefix/suffix/padding/yearly reset) and verified against your existing invoice history

Integration with your existing WooCommerce order emails and statuses, including any custom statuses from your fulfilment plugins

A short admin walkthrough document plus a screen-recorded handover showing template editing, bulk actions and the REST endpoint

Source code ownership for your site, with inline comments, a readme, and a staging-then-production deployment so live orders are never disrupted

Post-launch support window with bug fixes and compatibility checks against WooCommerce and WordPress core updates

Who this is for

WooCommerce store owner who wants invoicing to just happen

Sells daily and is tired of manually creating or emailing invoices. Wants every order to leave with a branded PDF invoice attached automatically, with correct sequential numbering for the bookkeeper — and wants ECOSIRE to set it all up rather than wiring plugins together themselves.

Operations / fulfilment manager shipping physical goods

Needs clean packing slips their warehouse can print in bulk from the Orders screen, plus credit notes for returns. Cares about HPOS compatibility, bulk print/merge actions, and the documents matching the company's branding and tax format exactly.

Finance or compliance lead needing audit-ready documents

Requires gap-free sequential numbering, proper VAT/GST tax IDs, proforma invoices for B2B quotes and credit notes for refunds — all archived and reproducible. Wants the document logic built correctly for their jurisdiction rather than a generic off-the-shelf template.

Frequently Asked Questions about PDF Invoices & Packing Slips Pro for WooCommerce

How long until the plugin is live on my store, and how is it delivered?

This is a build-to-order product, not an instant download. After we confirm your requirements (document types, branding, numbering, tax setup and which order statuses trigger emails), a typical build is delivered in about 2 to 3 weeks. We develop against a copy of your store, test on a staging site, then ECOSIRE installs and activates the plugin on your live WordPress site and verifies it against real orders. You receive the packaged plugin ZIP and the source code for your site.

Do I get ongoing support and updates after launch?

Yes. Every build includes a post-launch support window covering bug fixes and compatibility checks against new WooCommerce and WordPress core releases. Because the plugin reads and writes order data through WooCommerce's CRUD/HPOS APIs rather than the database directly, it is resilient to core updates. After the included window you can opt into an ongoing maintenance arrangement, or request changes (new document types, layout updates, extra integrations) as scoped follow-on work.

Will this work with HPOS (High-Performance Order Storage) and my existing plugins?

Yes. The plugin is declared HPOS-compatible and accesses orders only through wc_get_orders() and the $order object, so it works whether you use legacy post-based orders or the new custom order tables. We test it alongside your existing stack — payment gateways, shipping, subscriptions and any plugins that add custom order statuses — and hook into those statuses so invoices and packing slips fire at the right moment.

Can the invoices match my exact branding and tax requirements?

That is the main reason to build rather than buy off-the-shelf. We configure logo, colors, company details, footer terms and custom CSS in the template builder, and we set up your tax display — multiple tax classes, VAT/GST/Tax-ID labels, reverse-charge or zero-rated notes — to match your jurisdiction. If you need a layout an off-the-shelf plugin can't produce, we build it, because we own the template code.

Can other systems pull the invoices automatically?

Yes. The build includes a WooCommerce REST API endpoint that returns a given order's invoice or packing slip PDF, so your ERP, 3PL, or accounting tool can fetch documents programmatically. Documents are also archived as a custom post type and can be stored in a protected uploads directory or an S3-compatible bucket with signed URLs, so they are never publicly guessable. We scope the exact integration with you during the build.
