Invoice as downloadable product

Hello @radoslaws

It’s possible to download the Invoice in the thank you page using the shortcode.

To download it in the e-mail you need to attach it to the “New order email” under WooCommerce > PDF Invoices > Documents > Invoice > Attach to.

In addition to what my colleague @alexmigf said, if you want to see the link in the single order details (My Account > Orders > Order #{number}), please add the following code snippet to your site:

add_action('woocommerce_order_details_after_order_table_items', function(){
	if( ! is_admin()){
		echo do_shortcode('[wcpdf_download_invoice]');
	}	
}, 10, 1);

This will add the invoice link after the Order details heading:
