The simplicity of the interface, it's intuitively set up. It is very easy to use. I had no problems with anything or any learning curve needed. I can't think of anything that I dislike about this system. If you're looking for a simple solution for your business needs, then look into this software. They have many features in both the small and large businesses and you don't need someone to run their system all day every day to make it work. It helps me keep track of my inventory, purchase orders, sales tickets, and even my accounts payable and receivable.
