What happens when a product is sold out?
The results are slightly different between Etsy and Shopify.
When a product is sold out in Etsy, Syncr will set the Stock Levels to 0 in Shopify, and as a result it will be marked as ‘Sold Out’ in Shopify.
When a product is sold out in Shopify, Syncr will switch the product in Etsy to ‘inactive’ state, which will hide it in the Etsy shop. The reason that the stock is not set to 0 in Etsy is because Etsy does not allow for stock levels to be set to a number lower than 1.
In both cases, the products will effectively be hidden in the online shop, and will not be purchasable until the stock is update or the products are set to Active.
