what wmpu plugin can I use to sell on facebook from my wordpress site?

Please what wmpu plugin can I use to sell on facebook from my wordpress site/multisite?
Typically, I want to achieve something similar to shopify's method that allows a Shopify store owner to sell the products from his store on Facebook. The products are automatically synced so facebook users can buy directly from facebook.
Any app on wmpu to achieve this? Or any free opensource plugin to achieve this?

Thanks.
