Hi @blavery, I know we've been talking a bit about this offline but thought I'd weigh in here as well. I don't know of many e-commerce integrations offhand. We seldom see a direct selling play with online communities. Online communities are typically conceived of as a no-selling zone due to their more private nature. It's a great way to turn off customers and prospects if you are using the platform to sell. It's like inviting your friends to a barbecue and then telling them that you've brought them there to tell them about a great timeshare opportunity...
That's not to say that it cannot or should not happen if care is taken with the approach.
The element14 community has an ecommerce integration that helps you move from the discussion of a product to buying a component. Here's a screencast showing the process (it uses Flash, so you'll need to use Firefox or a browser that hasn't blocked it).
Also, here's a short think piece by Stephen Hamrick of SAP about considerations for integrating ecommerce with community platforms. I particularly liked his points about how essential enabling peer product reviews is. The upshot is that if you are going to integrate ecommerce with community, you must give careful thought to the customer journey to ensure that it's positive every step of the way. SAP Jam integrates e-commerce using Hybris. This Forbes article includes a helpful "Awareness to Advocacy" graphic.https://blogs-images.forbes.com/rawnshah/files/2015/10/Slide3.jpg?width=960
By the same token, here's a longer piece by Forrester called "Harness the Power of Communities To Improve the Online Commerce Experience." Like the shorter piece by Hamrick, this one talks about the usefulness of connecting the ability to buy and social reviews from within the online community experience. It also adds some use cases for including the ability to view multiple sources of community content from a product page and product detail pages. It also mentions having the ability to tag products from within community discussion pages. I know that element14 does this by enabling the ability to @mention any of its catalog products from within their Jive community.
What's interesting is that this more recent thought leadership sees a bright future for integrating e-commerce with online communities. IDC’s Social Business Futurescape predicts that by 2020, 30% of all purchases will be made through an online community. Though that may be so, I have seen precious few examples in the wild. And even the market-leading platforms like Jive and Lithium software seem to lack a dedicated e-commerce integration.
