On Friday, Groupon announced its acquisition of CommerceInterface, a Web-based channel management technology provider. The daily-deals company has used CommerceInterface technology to streamline its Groupon Goods operations and automate interactions with vendors since April 2012. “The acquisition enables Groupon to leverage infrastructure provided by CommerceInterface to support and optimize the Groupon Goods business around the world in 2013,” Groupon said in its press release. Current CommerceInterface clients will have to transition to other vendors with help from the company over the next six months. Groupon also noted in its press release announcing the acquisition that Groupon Goods had an annual run rate of nearly $1.5 billion in global billings in the third quarter. Terms of the deal were not disclosed. (Business Wire, TechCrunch)
