I like that it can be customized for our needs as we are in shipping very specific products. Their support team has been great at responding quickly and also have good suggestions for features when they don't know how to implement them themselves! We haven't found anything yet. It's easy to use once you figure out their system and navigate through all of the options. They do not offer any other services outside of Shipping so if you need help with invoicing or accounting this isn't something that will work for your business needs. This software allows us to manage multiple locations (we ship from two warehouses) easily and efficiently.
