Wholesale ordering & tracking

We would like a program wrote so our wholesale customer can log in, submit orders & track orders throughout our production processes. Each step I would like to have marked complete & then moved to the next process. We track the orders by Order #'s (this would be assigned by the program as they are submitted). They submit how many of each size & the product number. They also attach an image of what we are to decorate. Ordering Process 1) Submit an order (see attachment on the layout of an order) 2) Received product of the order 3) In Production 4) Ready for Pickup 5) Complete/Invoiced This is simply a way for our customer to submit orders to us.
