I use the Shopify integration to manage my stock levels, but they aren’t matching up

You can refresh individual products by checking the box next to the product and choosing the "refresh from Shopify" option in the dropdown. Then click submit: https://www.wolfandbadger.com/dashboard/integrations/shopify/linked/

In addition, you can update/refresh all products via the set-up page by clicking update: https://www.wolfandbadger.com/dashboard/integrations/shopify/unlinked/

To refresh the integration click on the "setup" tab and then click "reconnect". "Refresh from Shopify" will just refresh a specific product and won't get new products.
