Web Design for product tracking service

The website must be able to have a sign in area for customers or some other way of them identifying their order ie a product number system. It must also be easy for members of the company who are average web users to update the product status. I was thinking something like the UPS site, http://www.ups.com/tracking/tracking.html, where it then tells you at exactly what stage is required.
the stages needed for this tracking site would be
received
In copying
In cleaning
In packaging
Ready for collection
