Briteskies has been talking about B2B since before it was cool. In fact, Bill Onion has authored several articles that were published in 2011 for Multichannel Merchant, and we recently hosted an eCommerce Forum specifically on B2B alongside Magento. We even spoke at Magento Imagine about the topic as well. B2B should be treated with the same attitude as B2C. For more information check out our B2B Magento eCommerce page.
