I like how easy it was for me as an enduser with no coding experience, to get started using this product! The support team has been great in answering my questions quickly (and sometimes even before they asked) which made getting up and running much more efficient than if there were delays between asking question and receiving answer.
There are some features available only through their API - but not many so far. If you have limited development resources then definitely consider giving them a try. We're solving our inventory management problems by being able to report on stock location & quantity levels across multiple warehouses from one system.
