PDF Invoices & Packing Slips for WooCommerce – Challan

It was a bit of a surprise to discover that invoices and packing slips aren't part of WooCommerce. Fortunately, this plugin was freely available and creates very attractive packing slips or invoices right out of the box. Nice how Challan includes the WP site logo and title in the resulting PDFs. It's also highly configurable and pertinent text can be overridden where needed. 

Worked out great!
