WooCommerce requires at least: 2.2
WooCommerce tested up to: 2.4.12
While working on a project there was a situation where I needed to change the author assigned to a WooCommerce product. The product author was receiving unwanted notifications when reviews for the product were being left. We did not want to turn the notifications off; we just wanted them to go to a different author or user. Changing the author is easily possible with posts and pages, but the option isn’t available by default for WooCommerce products.
Adding the functionality is very simple – it involves adding author support to the product post type which can be accomplished by adding the following to your theme’s functions.php file:
<pre><code>if ( post_type_exists( 'product' ) ) {
 add_post_type_support( 'product', 'author' );
}
</code></pre>
However, for users who don’t want to touch the functions.php file, or would prefer a solution that is not restricted to a theme, I created this simple plugin. Just activate the plugin with WooCommerce also installed and you will be able to change the author of a product as if it were a standard post or page. 
After activating the plugin you will be able to change the author assigned to a WooCommerce product by editing the product in the WP dashboard. See screenshot for details.
If you do not see a place to change the author, check the screen options and make sure that ‘Author’ is checked. See screenshot for details.
<h4>Please note that WooCommerce must be installed and activated for the plugin to work.</h4>

Change Product Author for WooCommerce

Thanks Ollie! Perfect plugin, does exactly what it says.

Out of interest, any idea why Woo does not support author in core?

Perfect, as described

This makes it easy to change the author assigned to a WooCommerce product post type.

This plugin allows full control of your user permalinks, allowing you to change both the author base (the ‘/author/’ portion of the author URLs), and the author slug (defaults to the username of the author). You can set the author base globally, or you can set it to be user-specific based on a user’s role. You now have the power to craft the perfect URL structure for you Author pages.
WordPress default structure http://example.com/author/username/.
Edit Author Slug allows for http://example.com/ninja/master-ninja/.
Using a role-based author base would allow for http://example.com/ida/master-splinter/ (for an Administrator Role), or http://example.com/koga/leonardo/ (for a Subscriber Role).
