The ease of use, the fact that it's scalable across multiple platforms, the customer support team. It's not great at finding inventory issues in real time, but they have great tools for alerting you when something goes wrong. If you're looking to automate your inventory management, this is the way to go. You can do so much more with this platform than just inventory management. We've been able to build out our internal processes as well as our external fulfillment process. I like that it's easy, but also customizable so you can make changes as needed without having to hire someone else who has done this before in order to get things right! We've been using them since mid-2019 and have had no issues thus far. They do what they say they will be doing when hired - which was not just about adding inventory management features, but really getting into our store's data structure/logic flow to help us build out new products more efficiently than we could ourselves.
