Retail business seeks inventory management software that includes a point-of-sale module

We are an owner-operated retail business with a fairly large inventory, and we are looking for inventory management software that includes a point-of-sale module. We run an eBay shop, have our own online store, and also operate a brick-and-mortar store. It’s difficult to keep track of everything, so we’re now looking for a program that can handle this for us.

The following requirements should be met:

• Point-of-sale (for the brick-and-mortar store)
• Creating product listings with quantities and prices, and the ability to update quantities in real time
• Inventory management
• Interfaces for the three areas (physical store, our own online store, eBay store), and everything should be able to be consolidated within the program
• Most of the products have barcodes; these should be scannable
• Inventory management
• Network-compatible (MS Windows)
• Optional DATEV interface

Approximately 5 software workstations are planned.
