Need help choosing system for POS and Accounting

I am in the midst of trying to come implement a good system to integrate all aspects of our business but am having a very hard time figuring things out. This is for a clothing company that sells wholesale, retail via a website and operates 2 retail stores.

We'd like to be able to track everything together in terms of inventory, but would still like to be able to run each aspect of the business as a separate entity. We'd need to have 2 POS systems in one retail store and one in the other retail store. The wholesale sales could essentially be run as a 3rd store. Ideally, we need a system that allows for tracking materials and manufacturing. We'd probably want 2 people to be able to access the accounting/bookkeeping portion.

I'd really appreciate it if anyone had any suggestions as I am having a hard time figuring this out. Let me know if you need any more information.

As many know, I'm an advocate of NetSuite for this type of back-end functionality. They integrate inventory, accounting, sales, profits, custom reports, etc. very simply. You can regulate users and their access as well.

They are a full website operation system though, not just a back-office. Not sure if that's what you're looking for. They are also expensive, but the insight their reports and back end customization makes up for it in my mind.
