We are currently on channeladvisor and are desperately looking for an alternative. Our main issue is that we sell only in Canada on shopify, WalMart Canada, BestBuy Canada, NewEgg. Shipstation works fine with integration for us to Canada Post & UPS. I noticed shipstation integrates directly with shopify, BestBuy Canada, WalMart Canada, NewEgg, Canada Post, and UPS Canada. But is there a shipstation module to manage our products+inventory without using channeladvisor?
