What exactly is a net promotor score, you may be asking? NPS is a customer satisfaction benchmark that measures how likely your customers are to recommend your business to a friend. It's calculated based on one, simple question: "On a scale of 1-10, how likely is it that you would recommend us to a friend or colleague?" We are delighted to have received such great feedback from our customers and are grateful for any queries and comments that help us to continue improving our services.
