2 of 5 measures had too little evidence to score. They are left out of the total rather than counted as zero — otherwise a plugin would be marked down for being small rather than for being poorly kept.Measured 2026-08-02 from the WordPress.org plugin registry.
Ratings

No one has rated this plugin on WordPress.org yet. That is a statement about the ratings page, not about the plugin — plenty of well-kept plugins never collect them.

Simple Invoice Generator is a lightweight, easy-to-use WordPress plugin for generating PDF invoices. It also includes powerful WooCommerce support, allowing automatic invoice generation when customers complete an order.

🎉 WooCommerce Integration!
Automatically generate and attach a PDF invoice when a WooCommerce order is placed (e.g. after checkout or when an order is marked as completed).
You can enable or disable automatic invoice generation from the plugin settings page with a simple checkbox.

Also you can view and download the generated invoice directly from the order admin screen.

Core features:

  • Input invoice details (bill from / to, items, prices, tax, currency, etc.)
  • Automatically generates WooCommerce order invoices with proper customer data
  • Choose between two built-in PDF styles: Standard and Blue Accent
  • Upload a custom logo to display on the invoice
  • Preview and download the PDF file
  • All done without storing anything in the database

Great for freelancers, small businesses, or WooCommerce shops needing a simple invoice workflow!

Usage

🧾 Manual Invoice Creation
1. Go to the Invoice Generator menu item in your admin panel.
2. Fill in invoice details: invoice number, dates, billing info, line items, currency, and tax.
3. Optionally upload a logo to include on your invoice.
4. Select your preferred template style: Standard or Blue Accent.
5. Click Generate Invoice to create and download your PDF.

🛒 WooCommerce Invoices
– When a WooCommerce order is completed (or placed), an invoice is automatically generated.
– You’ll see the Invoice PDF download link directly inside the WooCommerce order admin panel.
– The generated invoice uses the order’s billing data, products, prices, currency, and tax details.

🛠️ Controlling Automatic Invoice Generation
You can toggle the automatic generation of invoices for WooCommerce orders on or off in the plugin settings:

  1. Go to Invoice Generator > Settings in the WordPress admin menu.
  2. Find the WooCommerce Integration checkbox.
  3. Check it to enable automatic invoice generation, or uncheck to disable.
  4. Save changes.

This gives you full control to disable invoice generation if you want to handle invoices manually or with another system.

License

This plugin is licensed under the GPLv2 or later.

Does this plugin store data in the database?

No. This plugin is purely frontend-driven for manual invoices. For WooCommerce orders, the generated PDF link is saved as order meta only.

Is WooCommerce required?

No, WooCommerce is optional. But if WooCommerce is active, the plugin will auto-enable invoice generation for orders.

Can I disable automatic invoice generation for WooCommerce orders?

Yes! From version 1.0.8 onward, you can toggle this feature in the plugin’s Settings page using the WooCommerce Integration checkbox.
