The following extensions, which I wrote for Magento Community Edition (CE), have all been discontinued.
Customizable PDF Invoice Module
This module divides the PDF invoice into ten style groups, each with its own font face and font size settings. Display the coupon code used with the order, hide item grid columns (SKU, tax, quantity, etc.), format the store address’s first line differently that the rest of the address, change the PDF page/paper size so that it’s not A4, add a footer…use this extension to configure the PDF invoice to meet your requirements!
Customizable PDF Packing Slip Module
Configure your PDF packing slip’s font size, font face and page size. Don’t need to display all of the item grid columns (quantity, SKU, product name)? With this extension, hide the ones you don’t want. Make the first line of your store’s address bigger and bolder. Display a logo without being constrained by Magento’s 200 x 50 pixel size limitation. Add a footer to the bottom of each packing slip.
Free Shipping Up-Seller Widget
Let your visitors know how close they are to qualifying for free shipping! Use this widget to place “spend $x more and receive free shipping” messages throughout your store. Once a visitor’s shopping cart total is sufficient to be eligible for free shipping, the widget’s message changes to inform the visitor of this fact.
Statistics Fetcher
Imagine being able to say informed about your online store’s recent happenings—recent orders, most viewed products, sales total, etc.—without having to fire up a web browser or log into Magento. Our Statistics Fetcher brings this information right to your desktop in almost real time!
