You probably can do it with Quickbooks - I am not an expert in your data, your mileage may vary. But, something like MS Dynamics (as mentioned above), xtuple, or others would give more functionality.
It sounds like that, so far, you are not using any financial software whatsoever. That is dangerous when running a business. You have to have a bookeeping system, either manual (nightmare for e-commerce) or computerized.
