This plugin extends the free version of WP eCommerce Shop Styling. The free version already allows customization of all email contents and use placeholders for all kind of customer and order informations.

The PDF invoice upgrade extends these great features and offers the ability to generate and attach an invoice to the order confirmation or an other outgoing mail.
You can change every line of text in the default template, use images and also customize the layout of the whole document.

None of these customizations need to write any code. It’s as easy as formatting a Word document.
