Etsy listing errors - quantity cannot be greater than 999

This error occurs when the total quantity of the product you are trying to list to Etsy is more than 999. Etsy does not allow listings to have a quantity more than 999 and as such rejects all such listings.

To resolve this issue, edit your failed listing to have the sum of the quantity for all the variations be less than 999, then "Save and publish" again to have your item successfully listed.
