I'm looking for some suggstions on a merchandise management system for my upcoming comic shop. I've got some financial backing so you don't have to limit yourself to cheap solutions.

My requirements:

It should have register/POS capabilities as well as inventory management, and intergrate with credit/debit card sales.

It should be able to run reports on sales, dead stock, maybe even project orders, etc.

It should allow for many different departments (comics, toys, videos, snacks, etc.), and for the reports to run by department.

It should not be hardware specific. I don't want to buy an IBM AS400 to get it to work.

It should beyond version 1.0

It should be supported by a company for tech support. I don't want to spend my days trouble shooting bugs.

Any suggestions/directions would be appreciated!
