Professional order system based on OS X + iOS

Dear MR users,

we're currently looking for a solution in our company for internal orders. Long story short, this is our dream scenario:


We have 4 stores.
Every store has to order a variety of products from our production facilities every day.
Every store will be be equipped with a Mac or iPad to do so.

The orders of these 4 stores will be automatically accumulated & processed in a central hub (cloud?).

We have 3 production departments for different product categories.
Every production department will be equipped with an iPad to display the quantity of ordered products.


Is there any way you can think of that will accommodate such a scenario in a intuitive and user-friendly manner?
Also, some leeway for customization would be appreciated.

Thanks in advance.
