I am looking for an inventory management software that I can rent
through an ASP.

We are a security integrator maintaining about 10,000 units of
equipment in inventory.  Right now, everything is done by hand.

We would like to do this on computer to track inventory in a more
sophisticated manner.  However, I am concerned about the cost of
purchasing a license for such software as well as the cost and
complications of having to manage the software internally.

We can certainly manage the bar code scanning.  I am hoping their is
an ASP inventory management solution, where we scan and it updates a
remote database via the Internet.

Please provide me with a viable recommendation.
