Their app is flawless in my opinion. Any customizations that you need, they can do it. They can take the most complex CSV file format from just about any source and extract the date so it's easily imported into Shopify. I could say so many AMAZING things about this company but seriously, it would take me forever. They are quick in replies to messages and never make you feel like your asking a dumb question. This companies exceeding standards in terms of their app and customer service should be a leading example to the other tech companies offering their service in this industry.
