Customers mostly browse the products they need online, make decisions on a specific item, and clearly enter into a deal with the retailer silently, without even notify anyone of their prospects and where. This is totally different from the experience they have while purchasing an item from offline retail stores, where they would find sales representatives if they have any questions about anything as such. In fact, the buyer can only have real interactions when they encounter a problem right after the sale. So, following the new trends, online marketplaces are eager to provide real-time business interactions with their customers. Therefore, live chat features are installed on the website or in the app itself to enhance shopping.
