hi @skyred Nice work however I would strongly recommend your module is renamed to avoid name space conflict with the drupal.org commerce_stock project.
@dwkitchen I have put up a post covering what the drupal.org commerce_stock for D8 module does see https://www.blue-bag.com/blog/stock-drupal-8-commerce-technical-overview... and I believe it will address all your needs.
I would appreciate feedback
