A WooCommerce invoice plugin looks simple until the store needs sequential invoice numbers, packing slips, credit notes, tax data, multilingual PDFs, customer downloads, bulk printing, or e-invoicing formats. At that point, the wrong plugin creates more manual work than it removes.
I prefer invoice tools that fit the order workflow instead of forcing staff to generate documents manually. Automatic email attachments, bulk actions, HPOS compatibility, clear numbering, and templates that can survive updates matter more than decorative PDF designs.
These five cover the strongest current use cases. For the wider store stack, see our best WooCommerce plugins. If invoices are only one part of improving checkout and order flow, compare our WooCommerce checkout plugins too.

How I Chose These Plugins
I compared current maintenance, WooCommerce and HPOS compatibility, automatic email attachments, bulk generation, invoice numbering, customer downloads, packing-slip and credit-note support, multilingual output, and how easy the templates are to customize without editing core plugin files.
1. PDF Invoices & Packing Slips for WooCommerce by WP Overnight – Best Overall
PDF Invoices & Packing Slips for WooCommerce is the most mature all-round choice here. It can automatically attach PDF or XML invoices to WooCommerce emails, generate packing slips, bulk-download documents, and let customers download invoices from My Account.
The reason I rank it first is depth without forcing a paid upgrade immediately. The free core already handles the normal invoice lifecycle, while paid extensions add proforma invoices, credit notes, premium templates, cloud upload, printing, VAT tools, and Peppol/e-document workflows.
Key features
- Automatic PDF or XML invoice email attachments
- Packing slips and bulk document generation
- Sequential invoice numbers
- Customer invoice downloads from My Account
- Customizable HTML/CSS templates
- Optional e-invoicing, credit-note, cloud, VAT, and printing extensions
Pros: Mature ecosystem, strong free core, modern e-document support, and good fit for stores that expect invoicing needs to grow.
Cons: Advanced compliance, credit-note, and automation features can require separate paid extensions or bundles.
Best for: Most WooCommerce stores, especially businesses that need reliable invoicing plus room to add compliance and automation later.
Pricing: Free core plugin. Professional extensions and bundles are sold separately by WP Overnight.
2. WebToffee WooCommerce PDF Invoices – Best for Shipping Documents
WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels is a strong fit when invoices are only one part of a larger fulfillment workflow.
I would choose it for stores that regularly need packing slips, delivery notes, shipping labels, and related order documents alongside invoices. Keeping those documents in one ecosystem is cleaner than stacking several small plugins.
Key features
- Automatic WooCommerce PDF invoices
- Packing slips and delivery notes
- Shipping labels
- Bulk print and download actions
- Customizable invoice templates
- Premium extensions for broader document workflows
Pros: Broad fulfillment-document coverage and a good fit for stores that print paperwork every day.
Cons: If you only need a basic invoice attachment, the larger document suite can feel unnecessary.
Best for: Physical-product stores that need invoices, labels, delivery notes, and packing documents together.
Pricing: Free core plugin. Premium document and customization features are available separately from WebToffee.
3. Challan – Best for Multilingual Invoices
Challan by WebAppick is a useful middle ground between a simple invoice generator and a larger logistics suite. It can generate invoices automatically, attach them to emails, create packing slips and credit notes, and support multilingual document workflows.
I like Challan for international stores that care about translation, currency output, and document flexibility but still want a usable free starting point.
Key features
- Automatic PDF invoice generation
- Email invoice attachments
- Packing slips and credit notes
- Multilingual document support
- Custom invoice templates and branding
- Shipping-label and advanced options in paid editions
Pros: Strong multilingual focus, useful free version, and good coverage of common invoice documents.
Cons: Some advanced shipping and customization features sit behind the commercial edition.
Best for: International WooCommerce stores that need invoices and related documents in multiple languages.
Pricing: Free core plugin with a paid Pro edition.
4. Print Invoice & Delivery Notes for WooCommerce – Best Lightweight Print Workflow
Print Invoice & Delivery Notes for WooCommerce by Tyche Softwares is the plugin I would choose when staff mainly need printable order documents from the admin rather than a complex automated invoicing platform.
It keeps the workflow simple and is especially useful for smaller physical-product stores that print invoices, receipts, delivery notes, and packing slips while processing orders.
Key features
- Printable invoices
- Delivery notes and packing slips
- Receipts
- Order-admin print actions
- Basic document branding
- Lightweight free workflow
Pros: Simple, established, and easy for warehouse or fulfillment staff to understand.
Cons: Less suitable for stores that need advanced e-invoicing, automated credit-note workflows, or complex compliance.
Best for: Small and mid-sized physical-product stores that mainly need clean printable order paperwork.
Pricing: Free.
5. WowInvoice – Best for Modern Templates and Partial-Payment Compatibility
WowInvoice is a newer option, but it is moving quickly and currently supports invoices, packing slips, credit notes, delivery notes, templates, and compatibility work around deposit/partial-payment plugins.
I would consider it for stores that want a more modern document interface and are also experimenting with deposits or partial payments. Because it is newer than WP Overnight or WebToffee, I would test the exact tax and accounting workflow before replacing a mature invoice stack.
Key features
- PDF invoices and packing slips
- Credit notes and delivery notes
- Multiple document templates
- Bulk export improvements
- Currency and tax display improvements
- Compatibility with several deposit/partial-payment plugins
Pros: Modern feature direction, active development, and useful compatibility work for more complex order-payment workflows.
Cons: Smaller install base and shorter production history than the established leaders.
Best for: Stores that want modern invoice templates and need compatibility with newer WooCommerce payment workflows.
Pricing: Free core plugin.
Which WooCommerce PDF Invoice Plugin Should You Choose?
For most stores, I would start with WP Overnight because the free core is mature and the extension path is clear. WebToffee is stronger when fulfillment paperwork is equally important. Challan is a good multilingual option, Tyche keeps simple printing lightweight, and WowInvoice is worth watching for modern order-document workflows.
Before switching invoice systems on an active store, test invoice numbering, taxes, refunds, customer downloads, multilingual output, and old-order document access. Accounting documents are one area where a visually nicer template is not enough.
Conclusion
A good WooCommerce invoice plugin should disappear into the order workflow. WP Overnight is my first choice for most stores, WebToffee is better for fulfillment-heavy businesses, and Challan is a strong multilingual option. Choose the system that handles the documents your staff and customers actually need, then test the accounting workflow before relying on it in production.
Frequently Asked Questions
What is the best WooCommerce PDF invoice plugin?
WP Overnight PDF Invoices & Packing Slips is the strongest all-round choice because it combines a mature free core with packing slips, customer downloads, templates, and optional compliance extensions.
Can WooCommerce automatically email PDF invoices?
Yes. WP Overnight, WebToffee, Challan, and several other plugins can automatically attach invoices to selected WooCommerce order emails.
Do I need a paid invoice plugin?
Not always. A free plugin is enough for many stores that only need sequential invoices and email attachments. Paid plans become more useful for credit notes, premium templates, cloud storage, advanced shipping documents, and e-invoicing.
Can customers download invoices from My Account?
Yes. Several plugins support secure customer invoice downloads from WooCommerce My Account or order pages.
Should I replace my invoice plugin on a live store?
Only after testing old orders, invoice numbering, taxes, refunds, and document access on staging. Invoice systems affect accounting records, so switching deserves more care than a normal visual plugin change.
