Chat Software to your E commerce website Increases sales

If you are running a E commerce store and imagine a visitor reaches your website and he got some doubts regarding your product and he is a real potential buyer and ready to buy the product immediately, if your website does not have an chat feature, the visitor has to email you or call you, and the response will take time, and in the search if he finds your competitor website and he got a chat facility definitely you loose the sales because he uses the chat feature to clear his doubt and purchases the product.
