Inventory Management, Sales company of 20 people.

Question

I want a program for inventory management for a company with 20 reps using ipads, all of the reps have ipads. We want to be able to monitor the reps inventory so that we can actively track the movement. Very important, this is not to track the sales of inventory, the actual distribution of inventory is done from the headquarters, and the inventory the reps have is for samples or distribution of inventory in the event that the product is needed immediately.
Basically we have a warehouse that monitors the inventory, but there are instances where a rep will give another rep a product to bring to the warehouse. And it becomes damaged or doesn't make it back, and then we have a hesaid/shesaid situation. So to avoid this I would like an application on the IPAD where we can actively tracky inventory.
If possible I'd like to be able to attach pictures, or scan the bar codes for every transaction as evidence of the transfer.
Now i don't know if this is beyond the capability of any apps available for the ipad, but to me it sounds as though this need is most likely very common for sales companies of any size.
I appreciate all of the help.

Answer 1

I'm still looking for a good answer. Most of the products I've come across have been more sales based and aimed at tracking sales. They seem more focused on revenues and such.
Even if someone knows a website that is accessible from an Ipad that would be great. I see 110 people have looked at this and not one response, so i'm starting to wonder if anyone knows the answer. I'm willing to register and pay an annual fee for all of the accounts we would have signed up.
Once again, thanks.
