Firstly advise me that salehoo does not have a system
I'm sorry but I'd have to disagree with this statement, if even if I am employed by SaleHoo which might make me bias :)
Firstly we don't have a business/auction management software. We offer a directory and a Link hidden: Login to view
not to mention great support for both!
I haven't used Treadeview so it wold be unfair to say anything about this software or application.
