We Compared the Best WooCommerce PDF Invoice Plugins

As a WooCommerce store grows, invoicing becomes less about creating a PDF and more about reducing repetitive work.

More orders can mean more invoices to generate, emails to send, customer download requests to handle, documents to organize, and fulfillment paperwork to manage. 

A plugin that works well for a small catalog may become cumbersome when those tasks multiply.

For this comparison, we focused on how each plugin handles automation, administration, customer access, document management, and growing operational requirements.

How We Evaluated These WooCommerce Invoice Plugins

We evaluated each plugin around the work a growing WooCommerce store needs to manage repeatedly.

Our main criteria were:

1. Automation: Can documents be generated and delivered without repetitive manual work?
2. Admin workflow: How practical is it to manage invoices and related documents at higher order volumes?
3. Customer access: Can customers retrieve their own invoices instead of contacting the store?
4. Bulk management: Can admins generate, download, print, or export multiple documents efficiently?
5. Document coverage: Does the plugin handle invoices only or extend into packing and fulfillment documents?
6. Customization: Can stores maintain consistent document information and branding?
7. Tax and e-invoicing: Does it support VAT information or structured electronic invoices where required?
8. Operational complexity: Does adding functionality require several extensions or separate plugins?

We used current official product pages, documentation, and WordPress.org listings for feature verification.

Best WooCommerce PDF Invoice Plugins for Growing Stores

01. PDF Invoices & Packing Slips for WooCommerce by WP Overnight

Best for: Stores that want a mature invoicing system with strong bulk management and structured e-invoicing support.

WP Overnight’s PDF Invoices & Packing Slips for WooCommerce has one of the longest-established ecosystems in this category. The current plugin has more than 300,000 active installations and over 1,800 WordPress.org reviews.

For a growing store, its main advantage is that the core invoicing workflow already covers the repetitive tasks that tend to increase with order volume.

Key capabilities:

• Automatically attach PDF or XML invoices to WooCommerce emails
• Generate invoices and packing slips in bulk
• Let customers download invoices from My Account
• Use sequential invoice numbering
• Customize invoice templates with HTML/CSS
• Generate structured invoice formats such as UBL 2.1, Peppol BIS 3.0, Factur-X, CII, and ZUGFeRD

Why it works for growing stores: Bulk document management and customer self-service reduce repetitive admin work, while its e-invoicing capabilities give businesses room to handle more demanding invoicing requirements without replacing the core system.

Main trade-off: Some advanced document and workflow functionality belongs to WP Overnight’s extension ecosystem. That gives stores flexibility to add what they need, but it can also make the complete setup less consolidated than an all-in-one document solution.

02. WowInvoice

Best for: Growing WooCommerce stores that want invoices and fulfillment documents managed through one centralized workflow.

WowInvoice takes a broader operational approach than a traditional invoice-only plugin. Its six primary document types are:

• PDF invoices
• Packing slips
• Picklists
• Shipping labels
• Delivery notes
• Credit notes

UBL invoices are available as an additional machine-readable invoicing option.

Key capabilities:

• Automate document generation based on WooCommerce order status
• Attach documents to WooCommerce emails
• Provide customer invoice downloads
• Manage document formatting and store information centrally
• Customize invoice and fulfillment-document layouts
• Support bulk document workflows
• Display VAT/Tax IDs on invoices and credit notes
• Support RTL document output

The main operational advantage is WowInvoice’s centralized document workflow. In our hands-on use, invoices, packing slips, delivery notes, and other documents are easier to manage because they are configured from the same dashboard using a similar setup model.

It also supports EU VAT documentation by collecting or retrieving customer VAT/Tax IDs and displaying them on invoices. Live VIES validation is not built in, so stores that need it must use a compatible VAT plugin.

Why it works for growing stores: It reduces workflow fragmentation when invoicing begins to overlap with picking, packing, shipping, delivery, and refunds.

Main trade-off: WowInvoice has a shorter public track record than WP Overnight, which may matter to stores that prioritize a long-established plugin ecosystem.

03. WebToffee

Best for: Stores that want to build a broader order-document system gradually as operational requirements expand.

WebToffee provides a strong core invoice product alongside a larger family of WooCommerce order-document plugins.

Its primary PDF invoice product can automate invoices, packing slips, and credit notes, attach documents to emails, give customers invoice downloads, manage numbering, and generate UBL/XML electronic invoices.

Key capabilities:

• Automatic invoice generation and email delivery
• Packing slips and credit notes
• Customer invoice downloads
• Bulk export with filters such as order status, customer, date, and payment method
• VAT and GST fields
• UBL/XML invoices
• Multilingual and RTL support
• Cloud backup through Google Drive, Dropbox, FTP, or SFTP
• Remote printing through PrintNode

Beyond invoicing, WebToffee offers additional products for shipping labels, delivery notes, dispatch labels, address labels, proforma invoices, and picklists. These can also be purchased together as a document suite.

This modular structure is useful for businesses whose operations are still evolving. A store can start with invoice automation, then introduce fulfillment or warehouse documents as those workflows become necessary.

Why it works for growing stores: It provides a clear expansion path without forcing every document workflow into the initial installation.

Main trade-off: The same modularity can increase complexity. A store that eventually needs the full document stack may end up managing several plugins or add-ons instead of one centralized solution.

04. YITH WooCommerce PDF Invoices & Packing Slips

Best for: Stores that need stronger back-office control over invoice generation, storage, and document administration.

YITH focuses heavily on managing invoices once order volume starts creating administrative work.

Its dedicated invoice dashboard allows admins to bulk generate, download, regenerate, delete, and export invoice data. Customers can also access generated invoices from their WooCommerce My Account area.

Key capabilities:

• Automatic or manual invoice generation
• Sequential numbering
• Dedicated invoice management dashboard
• Bulk document actions
• Credit notes and proforma invoices
• Packing slips
• Customer downloads
• Automatic Google Drive and Dropbox backups
• VAT and SSN checkout fields
• Nine templates and a Gutenberg-based template builder

Cloud backups can simplify document sharing with accountants, while its Gutenberg-based template system gives stores more control over invoice presentation.

Why it works for growing stores: YITH reduces invoice-administration friction through bulk actions, centralized management, and automated document storage.

Main trade-off: The depth of configuration may be unnecessary for merchants whose main requirement is simply generating and emailing invoices automatically.

05. Acowebs PDF Invoices and Packing Slips

Best for: Stores that place more emphasis on document presentation and customization.

Acowebs covers more than invoices. Its current plugin supports invoices, packing slips, shipping labels, delivery notes, and dispatch labels.

Key capabilities:

• Automatic PDF invoice generation
• Invoice attachment to WooCommerce emails
• Packing slips, shipping labels, delivery notes, and dispatch labels
• Customer invoice downloads
• Custom numbering
• Store branding
• Custom CSS
• Arabic font and RTL support
• Multiple invoice templates
• Drag-and-drop customization for invoices and selected fulfillment documents

For businesses that treat invoices and delivery documents as customer-facing brand assets, Acowebs gives more design control than many basic invoice plugins.

It can also keep several common order documents inside the same plugin rather than limiting the store to invoice PDFs alone.

Why it works for growing stores: It provides a practical combination of automated documents and branding control as customer-facing order communication becomes more important.

Main trade-off: Its strongest differentiation is customization rather than advanced tax or structured e-invoicing. Stores with complex electronic-invoice requirements may find WP Overnight, WebToffee, or a tax-focused solution more appropriate.

06: Flexible PDF Invoices for WooCommerce & WordPress

Best for: WooCommerce businesses whose growing invoice workload is closely tied to EU VAT and accounting requirements.

Flexible PDF Invoices differs from the other plugins because it can create invoices directly inside WordPress even when no WooCommerce order is involved.

That makes it useful when invoice administration functions as a broader accounting process rather than only an output of order fulfillment.

Key capabilities:

• Manual and automatic invoice generation
• Custom invoice numbering
• Proforma and correction invoices
• EU VAT-number fields
• VIES VAT-number validation
• OSS/MOSS support
• Reverse-charge workflows
• VAT currency conversion
• Bulk invoice downloads
• Reports and invoice templates

Its EU VAT tools are the strongest reason to choose it. The plugin documentation specifically supports VAT-number handling, VIES validation, reverse-charge invoicing, OSS workflows, and foreign-currency invoice requirements.

Why it works for growing stores: It handles administrative and tax complexity that may become more important as a business starts selling across EU markets.

Main trade-off: Its strength is invoice and accounting administration, not warehouse operations. Stores that need picklists, shipping labels, and delivery documents managed alongside invoices will need a broader fulfillment-document solution.

Which Invoice Plugin Fits Your Store as It Grows?

The best choice depends less on the total number of features and more on where increasing order volume creates work.

A useful way to choose is to identify the repetitive task you expect to increase first.

• If staff are repeatedly generating, downloading, or sending invoices, prioritize automation and bulk actions.
• If customers frequently request invoice copies, prioritize My Account downloads and automatic email delivery.
• If packing and shipping paperwork is becoming fragmented across several tools, consider whether a centralized or modular order-document system will reduce that complexity.
• And if international growth introduces VAT or structured e-invoicing requirements, make those requirements part of the decision before choosing based on document design or price.

The goal is not to buy the plugin with the longest feature list. It is to remove the administrative work that grows with your store.

Reducing invoice administration also frees up time to focus on customer growth and increase your average order value.

Final Verdict

For this comparison, WP Overnight is our first choice for growing WooCommerce stores that want a mature invoice workflow with strong bulk handling, customer access, and structured e-invoicing support. 

Its established ecosystem also gives businesses several ways to expand the setup as requirements become more complex.

WowInvoice is the better fit when growth creates broader fulfillment-document requirements and you want invoices, packing slips, picklists, shipping labels, delivery notes, and credit notes managed through a more consolidated workflow.

WebToffee offers another strong growth path for stores that prefer a modular document ecosystem, while YITH, Acowebs, and Flexible PDF Invoices become more compelling when invoice administration, branding, or EU VAT requirements dominate the decision.

Choose the plugin that removes the operational bottleneck your store is actually developing. As order volume rises, that matters more than simply having the longest feature list.

Once invoice and document operations are under control, the next growth opportunity is often increasing revenue from each order through strategies such as post-purchase upsells.
