Resyncing an Order from WooCommerce
If an order fails to sync initially, an email will be sent to the designated email address with an error message indicating what caused the Order to fail to sync. Once the order has been corrected, it is then ready to resync.
Inside WooCommerce, edit the order on the backend, on the edit order page you will see a Sync Order button, as shown below. Clicking this button will trigger the order to be resynced.
