PDF Invoices, Packing Slips & Credit Notes for WooCommerce

Key Features

Automatic PDF invoice attached to WooCommerce order emails on a status you choose (Processing, Completed, or custom) via the woocommerce_email_attachments filter

Packing slips and delivery notes printable individually or in bulk directly from the wp-admin Orders list and order detail screen

Credit notes auto-generated on WooCommerce refunds, sequentially numbered and linked back to the source invoice

Sequential document numbering with custom prefixes, padding and optional per-year reset, stored independently of the WooCommerce order ID

Customizable HTML/CSS PDF templates matched to your brand: logo, company address, footer terms, accent colours and fonts

Multi-language document output wired for WPML / Polylang so each customer gets their PDF in their locale

VAT / GST / tax registration number fields, tax-summary breakdown, and proforma + receipt document variants

HPOS-compatible — works with WooCommerce High-Performance Order Storage (custom order tables) as well as legacy post-meta orders

Documents archived as real files on the server (or S3) so they are reproducible months later, not regenerated from volatile cart state

WooCommerce REST API endpoint to fetch a given order's PDF programmatically for portals, ERPs or accounting sync

Manual 'regenerate' and 'attach to email' controls per order for re-sends and corrections

WP-Cron-based bulk export of date-ranged invoices to a single ZIP for your accountant

About this Product

Most WooCommerce stores still email a plain order-confirmation with no attached document — and WooCommerce core has no built-in PDF invoice generator at all. This plugin closes that gap. ECOSIRE builds, installs and configures a PDF Invoices, Packing Slips & Credit Notes plugin directly on your WordPress site, tuned to your branding, tax rules and fulfilment workflow.

Once live, every order automatically gets a branded PDF invoice attached to the WooCommerce order email (Processing, Completed, or a status you choose). Warehouse staff print packing slips and delivery notes straight from the Orders screen or in bulk; refunds generate sequential credit notes linked back to the original invoice. Documents carry per-year-reset sequential numbering with custom prefixes, your logo, company address, footer terms, and VAT/GST/registration fields — plus proforma and receipt variants where you need them.

Technically, the plugin hooks into WooCommerce's email actions (woocommerce_email_attachments, order-status transitions) and renders documents server-side, so they're reproducible and archived as files rather than fragile on-screen HTML. It is built HPOS-compatible (the new high-performance custom order tables) and works with the WooCommerce REST API for programmatic document retrieval. We wire it for WPML / Polylang multilingual output so each customer receives their invoice in their own language, and we respect your existing tax configuration rather than reinventing it.

Because this is build-to-order, you are not downloading a generic ZIP and fighting the settings yourself. ECOSIRE delivers a working, tested installation on WordPress 6.x + WooCommerce 8/9+, migrates your template design, and hands over documentation. Honest scope: it is not an instant marketplace download, and country-specific legal e-invoicing (ZATCA, PEPPOL, FBR) is a separate compliance product.

What you get

Fully installed and configured plugin running on your WordPress + WooCommerce site (staging first, then production)

One branded document template set: invoice, packing slip, delivery note, credit note, with your logo, address, tax fields and footer

Numbering scheme configured (prefix, padding, per-year reset) and back-dated start number agreed with you

HPOS compatibility verified and email-attachment trigger wired to your chosen order statuses

Multilingual output configured for your active WPML/Polylang locales (where applicable)

Short admin handover guide plus a recorded walkthrough of printing, bulk export and template edits

30 days of post-launch support covering bug fixes and configuration adjustments

Who this is for

Store Owner / Operations Manager

Runs a WooCommerce shop and wants every customer to receive a professional, branded PDF invoice automatically — without paying a developer hourly or wrestling a generic plugin's settings into shape.

Warehouse / Fulfilment Lead

Needs to print packing slips and delivery notes in bulk from the Orders screen each morning, with clear item, SKU and shipping detail, so pick-pack-ship runs without manual paperwork.

Accountant / Bookkeeper

Requires sequentially numbered invoices and credit notes with correct VAT/GST fields and a date-ranged bulk export, so month-end reconciliation and tax filing are clean and audit-friendly.

Frequently Asked Questions about PDF Invoices, Packing Slips & Credit Notes for WooCommerce

How long does delivery take, since this is build-to-order?

Typical turnaround is 5 to 10 business days from kickoff. We first install and configure on a staging copy of your site, confirm the template branding, numbering and email triggers with you, then promote to production. Complex multilingual or multi-tax setups can add a few days — we give you a firm date after a short scoping call. This is not an instant download; it is a built, tested installation on your own WordPress site.

What support and updates do I get after launch?

Every build includes 30 days of post-launch support for bug fixes and configuration tweaks. After that, optional retainer plans cover WooCommerce/WordPress version-compatibility updates, template changes, and new document types as your store grows. Because the plugin lives on your site, you own it outright — there is no per-store license that expires, and we can hand over the source on request.

Does this work with WooCommerce HPOS (High-Performance Order Storage)?

Yes. We build the plugin to be HPOS-compatible, so it reads orders from WooCommerce's new custom order tables as well as the legacy post-meta storage. We verify document generation and email attachment under whichever storage mode your store uses, and confirm it before handover.

Is this a legal e-invoicing / tax-authority solution (ZATCA, PEPPOL, FBR)?

No — and we want to be honest about that. This plugin produces professional, branded PDF business documents with VAT/GST fields, sequential numbering and proforma/receipt variants. Statutory e-invoicing that submits to a tax authority's clearance system (such as ZATCA Phase 2 in KSA, PEPPOL in the EU, or FBR in Pakistan) is a separate ECOSIRE compliance product. If you need both, we scope them together.

Can the invoices be multilingual and match my exact branding?

Yes. We design the PDF templates in HTML/CSS to your logo, colours, fonts, address block and footer terms — not a fixed generic layout. For multilingual stores we wire output to WPML or Polylang so each customer receives their invoice in their own language, with translated labels and the correct locale formatting for dates and currency.
