I am sure there are a few Apps that can be great alternatives to QuickBooks Commerce. It would be great if QuickBooks provided a list of options. Every business works differently and one App can be great for a company and not as good for another.
I can only reply for Erplain, we do provide Purchase orders, Sales orders, Shipping orders, multiple stock locations, custom price levels, and B2B Store (B2B ecommerce) among other features. Our pricing is very competitive.
