The best WooCommerce PDF invoice plugins automatically generate, customize, and email professional invoices the moment an order is placed or its status changes, so you never have to build a document by hand.
Below are ten tested options, what each one does well, and where each one falls short, plus a quick note on proforma invoices, since that’s a common source of confusion for stores that need to send a document before payment is collected.
A standard invoice confirms a completed sale. A proforma invoice is sent before payment, typically to give a customer a formal quote or a document for import/customs purposes. Not every plugin below generates both. We’ve marked which ones do.

Confirm current pricing and free-tier availability before publishing. Some sources list a free WordPress.org plugin alongside the premium suite; others describe it as premium-only. Check the live listing at time of publishing.

3. PDF Invoices & Packing Slips for WooCommerce by WP Overnight
This is the most widely installed plugin in this list, with 300,000+ active installs. It automatically attaches PDF invoices to order confirmation emails and lets you manage everything from the order admin page.
The free version now includes e-invoicing formats: UBL 2.1, Peppol BIS 3.0, CII D16B, Factur-X 1.0, and ZUGFeRD 1.0/2.0, at no cost. That’s a genuine advantage for stores that need structured e-invoicing for EU compliance, since most competitors charge for this or don’t offer it at all. The Plus Bundle (around €89/year) adds credit notes, proforma invoices, and delivery notes.
Key features:
- Automatic PDF attachment to order emails
- Free e-invoicing formats: UBL, Peppol BIS, Factur-X, ZUGFeRD

4. YITH WooCommerce PDF Invoices & Packing Slips
YITH’s plugin handles invoices, credit notes, and proforma invoices from one dashboard, with automatic backup to Dropbox or Google Drive. It now includes 9 templates built on a Gutenberg-based editor, so you can design layouts with blocks rather than raw CSS.
You can collect VAT or SSN numbers at checkout and have them appear automatically on the generated documents, which is useful for EU-compliant stores.
Key features:
- Manual or automatic invoice generation
- 9 templates with Gutenberg-based builder
- Sequential numbering with configurable prefixes and suffixes
- Automatic backup to Dropbox or Google Drive
- VAT/SSN collection at checkout
- Credit notes and proforma invoices included

5. Print Invoice & Delivery Notes for WooCommerce by Tyche Softwares
Tyche Softwares’ plugin now covers more than invoices and delivery notes. As of version 7.0.2, it generates invoices, receipts, delivery notes, credit notes, and packing slips as distinct, separately configurable document types, all printable directly from the order edit screen.
It’s used on 40,000+ WooCommerce stores and adds a print button to the customer’s My Account page for self-service access.
Key features:

- Print directly from the order edit page
- Print links added to customer emails
- Customer My Account print access
- Fully customizable templates per document type

6. PDF Generator For WP Pro
This plugin converts product pages, blog posts, and other site content into downloadable PDFs, with invoice generation as one supported use case rather than its core focus. If you specifically want a dedicated invoicing plugin, look elsewhere on this list first. If you also want to let customers download product pages or content as PDFs, this covers both needs.
It’s now HPOS-compatible and supports multisite installations, and integrates with Elementor, Divi, WPBakery, and Advanced Custom Fields.
Key features:
- Converts posts, pages, and products into PDFs
- Automated bulk generation via cron jobs
- Watermark support (text and image)
- HPOS and multisite compatible
- Page builder and ACF integration
- Invoice generation based on order status
7. PDF Invoices and Packing Slips For WooCommerce by Acowebs
Acowebs’ plugin covers invoices, packing slips, delivery notes, and shipping labels, with an advanced customizer for template design. It’s free on WordPress.org, with premium at $43/year for a single site, one of the more affordable paid tiers in this list.
Key features:
- Automatic PDF generation and email attachment
- Drag-and-drop advanced customizer
- Custom VAT, GST, and ABN fields
- Role-based access to invoices
- Multiple Google Fonts and RTL/Arabic font support
- Individual item packing slips
8. PDF Invoices for WooCommerce by Andrew Benbow
This plugin automates PDF invoice attachment to completed or processing order emails, with full template customization. It’s worth being direct about its scope: it generates invoices only. There’s no packing slip, delivery note, or credit note support, so if you need those document types, pair it with another tool or choose a broader plugin from this list. Pricing runs around €69/year.
Key features:
- Automatic PDF invoice attachment to order emails
- Fully customizable invoice template
- Legal company information sections
- Sequential invoice numbering
- Admin resend/download and customer My Account access
9. Flexible PDF Invoices for WooCommerce & WordPress by WP Desk
This plugin generates WooCommerce invoices and also lets you issue manual VAT invoices in plain WordPress, outside of WooCommerce orders entirely, which is useful if you invoice services alongside store orders.
Key features:
- WooCommerce and standalone WordPress invoicing
- VAT-compliant and VAT-exempt template options
- Bulk generation and download by date range
- Custom invoice numbering with shortcodes, prefixes, and suffixes
- WPML translation support
10. Sliced Invoices
Sliced Invoices is a general invoicing and quoting system for WordPress, built around client management, online payment collection (PayPal and Stripe), and reporting. It’s worth noting that PDF export specifically requires the separately priced “Email & PDF Invoices” extension. If PDF generation is your main requirement, factor that add-on cost in before comparing pricing against the other plugins on this list.
Key features:
- Invoice and quote creation with client management
- Online payment collection via PayPal and Stripe
- Custom terms, due dates, and payment tracking
- CSV export and reporting
- PDF export via paid extension
How to Create an Invoice Using Challan
Install and activate the free version of Challan. Once active, it automatically generates invoices, packing slips, and shipping labels for every existing and new order without further setup.
New order invoices are attached to order confirmation emails automatically. To download an invoice for a specific order, open that order’s page and use the Challan panel installed on the right side, or go to Challan > Settings > Bulk Download to export documents in bulk.
To customize the design, go to Challan > Settings > Template and select a template. Then go to Seller & Buyer to add your logo, address, company name, and VAT information, along with any footer content.
The Pro version adds a much wider set of customization options, along with ZATCA/GST compliance and order-language invoicing for multilingual stores, covered earlier in this article.
Frequently Asked Questions
Does WooCommerce generate invoices automatically?
No. WooCommerce doesn’t include built-in PDF invoice generation. You need a plugin like the ones covered here to automatically create and attach invoices to order emails.
What’s the difference between a WooCommerce invoice and a proforma invoice?
A standard invoice confirms a completed sale and is usually sent after payment. A proforma invoice is sent before payment, often for quotes, deposits, or customs and import documentation. Among the plugins covered here, WP Overnight (Plus Bundle), YITH, and WebToffee’s suite generate proforma invoices; the others are invoice-only.
Is there a free WooCommerce PDF invoice plugin?
Yes. Challan, WP Overnight, YITH, Tyche Softwares, and Acowebs all offer functional free versions on WordPress.org. Paid tiers typically add credit notes, proforma invoices, and deeper template customization.
Do these plugins support VAT, GST, or other tax fields?
Most do. Challan Pro, YITH, and Acowebs support custom VAT/GST/ABN fields, and WP Overnight’s free version includes structured e-invoicing formats (UBL, Peppol BIS, Factur-X, ZUGFeRD) built for EU tax compliance.
Which plugin should I use if I need EU e-invoicing formats like UBL or ZUGFeRD?
WP Overnight includes these formats in its free plugin, which makes it the most straightforward option if structured e-invoicing compliance is your main requirement.
Key Takeaways
- WooCommerce doesn’t generate PDF invoices natively, so a plugin is required for automated invoicing.
- Challan, WP Overnight, YITH, Tyche Softwares, and Acowebs all offer usable free versions; the rest are paid-only or require a paid extension for PDF export.
- Proforma invoices aren’t universal. Confirm a plugin supports them before choosing it for pre-payment or customs documentation needs.
- WP Overnight’s free tier now includes EU e-invoicing formats (UBL, Peppol BIS, Factur-X, ZUGFeRD), a meaningful differentiator for compliance-focused stores.
- Sliced Invoices requires a separate paid extension for PDF generation. Factor that into cost comparisons.
- Andrew Benbow’s plugin is invoice-only, with no packing slip or credit note support, unlike most other options here.
- Challan’s free version includes packing slips and shipping labels at no extra cost, while some competitors reserve those for paid tiers.
Free version on WordPress.org. Every Pro licence includes a 30-day money-back guarantee.
