It is easy to use as well as has all necessary features like shipping options etc., The interface is simple enough that even I can understand it very easily! They have great support team too who are always ready at your help when you need them most! Nothing much about this software but would say their business model needs some changes in terms of pricing structure which could be improved upon! Shipping, tracking & managing orders from one place was my main problem with other platforms so far (like Amazon).
This solved the problems pretty effectively and now everything seems perfect just by using NFS.
