The UL OpenMarketplace provides vendors and developers with an option to sell their products or solutions if they do not already have another mechanism for doing so, or for doing it internationally. The ideas is that users would always "shop" in the main Unified Listing itself. For those companies or developers who do not have a place to sell from, the UL OpenMarketplace can provide them with a place to put a detailed description page and a checkout page to sell their product from.
