Good question... I dunno what is the right answer to your question. I'll do some Googling and get back to you if I got an decent answer. You should email the people at iPage as they probably could give you help..
Order Manager WITHOUT Extended Support $995.
It looks nice but.....
Additional shopping cart licenses - only $300 per cart type..
On one hand they say it is good if you ever decide to switch carts but if you do that it will cost you another $300..
It has gotta boil the osC makers blood when they see other companies capitalizing on their work..
I don't know how Open Source survives.....
Actually this product is very powerful. I have it running with my yahoo store which delivers realtime inventory from my POS. Don't think of the product capitalizing on an open source product, think of it as a backoffice product that streamlines your internal business process. It does many things that osc doesn't do out of the box. It has incredible order management tools. The only downfall is that you must have access to run it..
Other than that, it is incredible. I only wish I can get a realtime inventory module for osc..
I know a company that uses it and if you have somebody that is good with access it is AWESOME. they process about 800 orders a day. it takes the customer service reps a while to understand it but they arent that computer literate and they eventually figure it out...
