ShipStation

ShipStation is invaluable for when your business starts to take off. It does so much—easy shipping (of course), batching, and yes, REPORTING. I only have the cheapest Shopify account type so the basic-but-useful reporting is much appreciated. Sure, the interface is dated and could use a tweak here and there (I'm a user experience expert as well, so this could be my bias) but its utility totally compensates for the look & feel. Also, the customer support is fantastic. Write an email and get an answer from a real live human being who speaks fluent English. Hooray!
