Hey, I need an ecommerce solution, basically a shopping cart software, which allows the following: 1. Multiple vendors, meaning that for the customers, there is only one catalog/view with all the products, but there are multiple admins, of which each one can only access to their own products and see sales reports accordingly. 2. The payment integration should allow a percentage to be deducted from each transaction. (The commission to the site owner) 3. Ideally I´m looking for open-source, free of charge possibilities. 4. Have been looking into OsCommerce (kind of has solution, but is outdated) and Magento, where this feature seems to be available at least with payment. Has anyone experience reaching something like this in Magento for example? Thanks in advance!
