Years ago I discovered Shopify while building my own clothing line.
At the time, the platform was just going public. The stock soared but they ran into some troubles due to Citron exposing some of their darker and misleading marketing tactics.
With all that being said, I am still impressed with Shopify. I love the ease of their platform because it makes it possible for every day people to create online stores.
I love the functionality because they really thought ahead and added features that make selling products online much easier, such as tracking information and ways to manage inventory very easily.
All in all, I rate Shopify very high. They have 24/7 service and it is the only web platform that helps its users in such a way that it does.
