Hi, I would suggest we do a web application which can run on any computer over the internet (or a local connection) by which even multiple people can access the system same time and work. We could also integrate import/export, stock notifications and some other innovative components and make a really good product to fit your need. I may be low on rating, but i can share some of my work with you if interested. By the way, I'm a well experienced Web Application developer/freelancer. :)
