All active products are synced to Sumtracker. This is done to avoid syncing a backlog of outdated draft products that may be present on the Shopify store.
We do not sync products without SKU on Shopify to Sumtracker. If you do not use SKU for certain products on Shopify, you may copy their names into the SKU field, in order to sync them to Sumtracker.
We do not sync draft products. The product needs to be active. if you do not want it to be available on the online store you can make it unpublished by removing the online store from the product channels on shopify admin.
