I am the owner/founder of Nesting Days -- an online B2C business on the Shopify platform.
I've been using Shopifty integrated with Shipstation for two year, and recently I've run into an SKU problem that results in the wrong SKU being imported to Shipstation.
I've contacted Shipstation and I've tried to follow their suggestions - but I realize I really need
1.) an 'overhaul' on existing SKUs in my products list
2.) help on creating new SKU's in Shopify and Shipstation for new 2017 inventory
3.) on-going support
Please contact me by emailing me at firstname.lastname@example.org
