12 WooCommerce PDF Invoice Plugins for Tax Compliance & Billing

Every WooCommerce order ends with a piece of paper that matters more than most store owners realize: the invoice. It is the document your customer uses for returns and warranty claims, the record your accountant files at tax time, and in many countries a legal requirement with strict rules about numbering, tax details and retention. WooCommerce’s default order email is not an invoice, which is why the best WooCommerce PDF invoice plugin for your store can save hours every month and prevent expensive mistakes.

This guide compares 12 WooCommerce PDF invoices plugin options, from free tools that attach a basic PDF to the order confirmation email to full document suites that produce credit notes, proforma invoices, picklists, dispatch labels and UBL e-invoices. We reviewed each plugin’s official listing, documentation and changelog in November 2026, and we read what the top-ranking guides from RexTheme, WP Engine and WebToffee cover. Then we added what they leave out: invoice compliance basics, e-invoicing formats, PDF engines, hooks and template overrides, checkout fields for VAT and Tax ID, and a go-live checklist.

Short answer: WowInvoice and WP Overnight’s Professional extension cover the widest set of documents, YITH is a strong pick for Italian e-invoicing and cloud backup, Print Invoice & Delivery Notes is a solid free option, and Invopack is a lean, low-cost choice for invoices, packing slips, credit notes and bulk ZIP export. Disclosure: Invopack is built by aThemeArt, the publisher of this guide, so we describe its limits as plainly as the others. This article is general information, not tax or legal advice, so confirm invoice rules with your accountant or local tax authority.

Quick Picks: The Best WooCommerce PDF Invoice Plugin for Each Need

What a WooCommerce PDF Invoice Plugin Does

A PDF invoice plugin turns order data into a formatted document at the right moment, then delivers it to the right people. When an order reaches a status you choose, such as Processing or Completed, the plugin performs automatic invoice generation, adds your company logo and business details, assigns the next invoice number and attaches the PDF to the order confirmation email. Customers can usually download it again from a My Account page invoice link, and you can bulk download PDF files for your accountant.

Most plugins in this guide also produce companion documents, because an order generates more paperwork than a single invoice:

If you also manage stock and fulfilment, our guide to WooCommerce inventory management pairs well with picklists and packing slips.

Invoice Compliance Basics: Numbering, VAT and E-Invoicing

A plugin cannot make you compliant by itself, but a good one gives you the controls compliance depends on. Rules differ by country, so treat the points below as a checklist of features to look for rather than legal advice.

Sequential invoice numbering

Many tax authorities expect invoice numbers to be unique and sequential. The EU’s basic VAT invoicing rules, set out in the VAT Directive and summarized on the European Commission’s VAT invoicing page, combine EU-wide requirements with national rules set by each member state. Look for sequential invoice numbering with a custom prefix and suffix (for example INV-2026-000124), zero padding, a yearly reset option and a separate sequence for credit notes. Some plugins can also reuse the order number, which is simpler but can leave gaps.

Business details, VAT number, SSN and Tax ID

Invoices usually need your legal business details (name, address, registration and VAT number) and, for B2B sales, the buyer’s VAT number or Tax ID. In some markets a national ID or SSN may also appear. Plugins differ here: YITH can add VAT and SSN fields at checkout, WowInvoice reads VAT numbers from several EU VAT plugins, and others rely on meta fields you add yourself.

Tax summary table and EU VAT compliance

For EU VAT compliance, an invoice should show tax clearly: rates, taxable amounts and tax amounts. A tax summary table that groups totals by rate makes documents easier to read for accountants and auditors. Check that the plugin itemizes tax by rate, shows prices inclusive or exclusive of tax the way your customers expect, and handles refunds with a matching credit note.

E-invoicing formats: UBL 2.1, Peppol, Factur-X and ZUGFeRD

More governments are moving from PDF invoices to structured, machine-readable ones. In the EU, recent VAT in the Digital Age (ViDA) reforms freed member states to introduce e-invoicing mandates without waiting for Commission approval, so requirements are evolving country by country. For automated e-invoicing, these are the formats you will hear about:

• UBL 2.1: the Universal Business Language, an XML format published as an OASIS standard. You can read the UBL 2.1 specification on the OASIS site.
• Peppol: a network for exchanging e-documents between businesses and governments. Peppol invoices are commonly built on UBL, so a plugin that outputs UBL is a step toward Peppol, though sending usually requires an access point service.
• Factur-X and ZUGFeRD: hybrid invoices that embed structured data inside a PDF, used in France and Germany.
• FatturaPA: the XML format required for Italian electronic invoicing, which YITH supports.

Among the listings reviewed for this guide, WowInvoice and WP Overnight mention UBL, YITH covers the Italian XML, and none advertises Factur-X or ZUGFeRD directly. If you need those, look for a dedicated add-on and confirm what your tax authority accepts.

How We Evaluated These Plugins

We compared plugins using their official product pages, wordpress.org listings, marketplace pages and changelogs, plus the three competitor guides mentioned above. Six points mattered most:

• Document coverage: invoices, credit notes, packing slips, delivery notes, proforma invoices, labels.
• Automation: order status triggers, email attachments and bulk actions.
• Compliance tools: numbering control, VAT and Tax ID fields, tax breakdown and e-invoicing.
• Customization: template builders, HTML and CSS overrides, fonts, RTL and translations.
• Maintenance: recent updates, WooCommerce and HPOS compatibility, support quality.
• Cost clarity: free versus paid features and licensing model. Prices and tiers change, so confirm on the vendor page before buying.

01. WowInvoice

WowInvoice by WPXPO is the broadest document suite in this guide. One plugin generates PDF invoices, packing slips, picklists, shipping labels, delivery notes, credit notes and UBL invoices, and it can create them automatically from order statuses or in one click for old orders. That makes it a strong candidate when you want a single tool for the whole pick, pack, ship and record workflow.

Its EU VAT handling is a standout. WowInvoice can show VAT numbers or Tax IDs beside billing and shipping addresses, use standard or custom labels and pull the number from its own checkout fields or from third-party EU VAT plugins such as Germanized, EU VAT Assistant and the YITH EU VAT plugin.

Key features

• Automatic invoice generation on chosen order statuses, plus manual and bulk creation for old orders
• Invoices, packing slips, picklists, shipping labels, delivery notes, credit notes and UBL invoices
• Email attachments by order status and download links in My Account and order emails
• Custom numbering with prefix, suffix and minimum length, with live preview
• Barcodes and QR codes, RTL support, a paid watermark and warehouse email notifications
• Bulk export of PDF invoices and ready-made, customizable templates

Scope of use: end-to-end B2B ecommerce billing, VAT-aware invoicing and order fulfilment. It requires WordPress 6.0+ and WooCommerce 7.0+.

02. Invopack

Invopack, published by aThemeArt, turns each order into an invoice, packing slip and, after refunds, a credit note without manual work. You enter company details once, pick one of three designs (Modern, Classic or Minimal) and let the plugin handle numbering, tax breakdown, barcodes, customer downloads and bulk export. It is deliberately simple, which suits small and mid-size stores that do not need a large add-on ecosystem.

Invoices generate when an order reaches the status you choose, including custom statuses, or manually from the PDF Documents box on the order screen. You then decide which WooCommerce emails carry the attachment. Packing slips list products, quantities, SKUs and variation details with a pick-and-pack checkbox column, hide prices and can show shipping method, weight, dimensions and a Code 128 barcode. Customers download invoices from My Account, the order view page or the thank-you page, and guests use a secure link built on the order key.

Key features

• Automatic PDF invoices on Processing, Completed or custom statuses, plus manual generate, regenerate and download
• Sequential numbering with prefix, suffix, zero-padding and yearly, monthly or no reset, using a {prefix}{number}{suffix} format
• Automatic credit notes for full and partial refunds with their own prefix
• Bulk generate and download invoices or packing slips as a ZIP
• Logo, company details, VAT or tax number, terms, footer, brand colors, fonts, paper size and orientation
• Itemized tax by rate, discounts, shipping, payment method, transaction ID and order currency
• HPOS compatible, Dompdf bundled, translation ready

Scope of use: day-to-day PDF packing slips, invoices and refund paperwork. It needs WordPress 6.0+, PHP 7.4+ and WooCommerce 7.0+, and it is priced at $19 on its product page.

09. WooCommerce PDF Invoice & Packing Slip with Credit Note (CodeCanyon)

This CodeCanyon plugin from RedefiningTheWeb is one of the more active paid options. It lists two invoicing modes: a normal invoice generated when the order is completed, and a proforma invoice created for new orders and updated when the order changes. It also generates credit notes, packing slips and shipping labels with barcode and QR code, and it can download invoices from a chosen date range as a ZIP.

Customization goes deep for a plugin at this price: WP Editor-based header, footer and body, buyer and seller blocks, watermark text or image, 56 fonts, 266 page sizes, portrait or landscape and tax display with rate and net amounts. The vendor’s numbering note says regenerating a completed order’s invoice keeps the same number, which helps avoid duplicates. Its changelog mentions HPOS compatibility since version 3.0.0, the mPDF library, EU VAT number support and extras such as HSN codes and amounts in words (including the Indian number system), which are handy in South Asian markets.

11. Invoice Generator for WordPress with WooCommerce, Stripe & AI (CodeCanyon)

This one is a different kind of tool. Rather than a pure WooCommerce document plugin, it is a standalone WordPress invoicing plugin with a clients and items database, 12 invoice templates, periodic (recurring) invoicing, Stripe payment links, a currency exchange option through xe.com and a REST API. It can also create invoices from WooCommerce orders, attach them to orders and let customers see their assigned invoices on a page through a shortcode.

That makes it useful if you bill clients for services or manual orders alongside your shop, which is a common B2B ecommerce billing situation. A recent update added an AI assistant that drafts invoice data and emails using your own OpenAI API key, so consider the privacy implications before sending customer details to a third-party AI service.

Key features

• Create, send and manage PDF invoices with clients and items
• WooCommerce integration: invoices on chosen order statuses and order previews
• Periodic invoices, Stripe payment links and payment history
• Currency exchange integration, REST API and HTML email templates

Side-by-Side Comparison

This table summarizes how each plugin is sold and what it is strongest at. Features and tiers change, so confirm details on the vendor page.

How to Choose the Right Plugin

Finally, remember that invoice plugins are just one layer of a healthy store. See our list of essential WooCommerce plugins for the rest of the stack.

PDF Engines: Dompdf, mPDF and TCPDF

Behind every plugin sits a PHP PDF generation library that converts HTML and CSS into a PDF. The engine decides how well your invoice handles fonts, right-to-left text and complex layouts, so it is worth knowing which one you are using.

If your invoices need Arabic, Hebrew, Bengali, Chinese or other scripts, choose a plugin with RTL support and custom font embedding, or one that works with mPDF. Browse the mPDF documentation if you want to understand how fonts and right-to-left text are configured.

Customization: Templates, Hooks and Checkout Fields

HTML and CSS template overrides

Most developer-friendly plugins let you copy a template into your child theme and edit it, which gives you HTML CSS customization without touching plugin files. For example, Invopack documents are overridden by copying a template to your-child-theme/Invopack/invoice/default.php, where $order, $document, $company and $settings are available. A country-specific note after the footer looks like this:

if ( 'US' !== $order->get_billing_country() ) {
    echo '<p>International order: add your customs or tax note here.</p>';
}

WooCommerce hooks and filter hooks

Plugins expose their own action and filter hooks in addition to WooCommerce hooks such as email and order-status actions. If you build for clients, our reference to the WooCommerce hooks list with examples is a useful companion. As an example, WP Overnight’s free plugin exposes template actions such as wpo_wcpdf_after_document, which you can use to print an order meta field on invoices:

add_action( 'wpo_wcpdf_after_document', function ( $template_type, $order ) {
    if ( 'invoice' !== $template_type ) {
        return;
    }

    $vat = $order->get_meta( '_billing_vat_number' );

    if ( $vat ) {
        echo '<p>Customer VAT ID: ' . esc_html( $vat ) . '</p>';
    }
}, 10, 2 );

Checkout fields for VAT number and Tax ID

If your plugin does not add a VAT or Tax ID field, you can add one with a filter. WooCommerce stores custom billing_ fields as order meta automatically, so the value is available to any invoice plugin that can print meta fields. For more on adding fields, see our guide to custom fields in WooCommerce.

add_filter( 'woocommerce_checkout_fields', function ( $fields ) {
    $fields['billing']['billing_vat_number'] = array(
        'type'     => 'text',
        'label'    => __( 'VAT / Tax ID', 'your-textdomain' ),
        'required' => false,
        'class'    => array( 'form-row-wide' ),
        'priority' => 125,
    );

    return $fields;
} );

Always validate the number format for your market, and avoid printing sensitive identifiers such as an SSN unless the law requires it.

Languages and currencies

Selling in several languages? Make sure the plugin is WPML translation compatible or Polylang ready so labels, tax names and document titles follow the order language. WP Overnight Professional and Flexible PDF Invoices both mention multilingual support, and YITH supports WPML and Loco Translate. If your store also serves multiple regions, our roundup of multilingual WordPress themes can help you pick a front end that works with translation plugins.

Go-Live Checklist for Compliant Invoicing

1. Enter complete business details: legal name, address, registration number and VAT number, plus your company logo.
2. Choose the trigger statuses: usually Processing or Completed for invoices, and Refunded for credit notes. Match them to the emails you attach documents to.
3. Set numbering: sequential invoice numbering with a custom prefix and suffix, and a separate credit note sequence. Decide on a yearly reset.
4. Add buyer tax data: VAT number, Tax ID or SSN fields at checkout where needed, and test B2B and B2C orders.
5. Check the tax summary table: confirm rates, inclusive or exclusive prices and rounding on multi-rate orders and refunds.
6. Test emails: place orders in each status and confirm the PDF arrives on the right email and opens correctly.
7. Test customer access: My Account links, thank-you page links and guest links.
8. Test warehouse documents: packing slips without prices, labels and barcodes or QR codes, then print them.
9. Back up before going live: database and the PDF folder. Our guide to a database backup plugin setup covers snapshots and restores, which also protect your invoice counters.
10. Set up storage and retention: decide where PDFs live (server, Dropbox, Google Drive or SFTP) and how long you must keep them in your country.

Common Problems and Fixes

• No PDF attached to the email: the document is probably tied to a different order status or email type. Check which emails are selected for the attachment and which status triggers generation.
• Duplicate or skipped invoice numbers: avoid generating the same document from two overlapping settings, test with several orders placed at once, and never edit the counter casually on a live store.
• Blank or broken PDFs: raise the PHP memory limit, check error logs and make sure the PDF folder is writable. Large catalogs with images can exhaust memory.
• Squares or missing characters: your font does not include the script. Switch to a Unicode font or an engine like mPDF with the right font.
• Wrong currency symbol or missing items after an update: update on staging first, then compare a sample invoice with the previous version.
• Customer data privacy: invoices contain names, addresses and tax IDs. Make sure stored PDFs are not publicly guessable. Some plugins add random tokens to filenames and expire stored files.
• Documents saved in different places: some tools store PDFs on disk, others regenerate them on demand and standalone invoicing tools keep their own records. Know which one you use before you migrate.

FAQ: WooCommerce PDF Invoice Plugins

What is the best WooCommerce PDF invoice plugin?

There is no single winner. WowInvoice and WP Overnight Professional cover the most documents, YITH is strong for Italian e-invoicing and cloud backup, Print Invoice & Delivery Notes is a good free option and Invopack is a low-cost choice for essentials. Pick based on the documents, countries and languages you need.

Does WooCommerce create PDF invoices by default?

No. WooCommerce sends order emails but does not generate numbered PDF invoices. A plugin adds invoice creation, numbering, branding and email attachments.

Can a plugin make my invoices legally compliant?

A plugin provides the tools, such as sequential numbering, VAT fields and tax breakdowns, but you remain responsible for meeting the rules where you operate. Ask your accountant or check your tax authority, because requirements vary by country and are changing in many places.

What is the difference between an invoice, a proforma invoice and a credit note?

An invoice records a completed sale. A proforma invoice is a preliminary document issued before payment or shipment. A credit note records a refund or reduction against an earlier invoice.

Do I need UBL, Peppol, Factur-X or ZUGFeRD?

Only if your customers, governments or accounting systems require structured e-invoices. UBL 2.1 and Peppol are common in public procurement and several countries, while Factur-X and ZUGFeRD are hybrid PDF formats used in France and Germany. Check local rules before paying for a feature you may not need.

Can customers download invoices themselves?

Yes, most plugins add a download link to My Account and the order view page, and some also support guest links in order emails. Invopack, WowInvoice, WP Overnight, YITH and Print Invoice & Delivery Notes all offer customer access.

Can I generate invoices for old orders?

Often yes. WowInvoice creates invoices for new and old orders with one click, and several plugins support bulk generation from the Orders list. Check numbering behavior first so old orders do not disrupt your sequence.

Do I need a WordPress invoicing plugin or an accounting tool?

If you only need documents for WooCommerce orders, a PDF invoice plugin is enough. If you need bookkeeping, payment reconciliation or tax filing, pair it with accounting software. A standalone WordPress invoicing plugin makes sense when you also bill clients outside WooCommerce.

Final Thoughts

Good invoicing is invisible when it works: the PDF arrives, the numbers add up, the refund has a credit note and your accountant gets a tidy export. Start by listing the documents you need, the countries you sell to and the languages your customers read. Then shortlist two plugins, test each on a staging site with real order scenarios and choose the one whose numbering, tax display and support you trust.

Whichever you pick, keep backups, test updates on staging and review your settings whenever tax rules or your business details change.
