Here is one we launched a few months back.

The client has enjoyed increased sales. We have made some custom changes so their Dealers (with special pricing and delivery) can login and now order 24/7 instead of normal business hour only.
We modified a nop-template theme, thanks to Shawn (nopadmin helping pull customers, orders products and categories from previous e-commerce platform (allowing customers to login and see all the orders they had placed going back to 2009) and the awesome Shipping Director and Payment Director plugin from NopTools thanks Dennis.
We are in process of converting all of our clients to Nop Commerce as there really is no solution better (I have been developing e-commerce sites for close to 20 years and customized many platforms over the year) thanks to Nop Commerce and the great community here.
