Delete product variants after they're sold in Shopify by using Arigato Automation
Remove shipped items from the product list upon purchase for accurate tracking.
This automation fires when an order is fulfilled in your Shopify store. It then delays the workflow from running for one day, to ensure that it wasn't a mistake that this order was fulfilled. After that, this workflow makes use of a variant subworkflow. Opening it reveals that it checks to see if the variant title does not equal the default title. If this condition is true, it will delete the product variant.
This automation is useful if you only have one of the product variants that you sell. It will automatically remove the variants, ensuring that your store's front end remains up to date at all times.
