To be able to do that, it is important to fully understand NPS.
In Net Promoter Score (NPS), loyal customers are called Promoters. These are essential to your company. Sounds obvious, but why is this the case? It’s not just the money your customer spends that is important, his enthusiasm and the things he tells others about you are at least as significant. Promoters keep doing business with you, which is actually 5 times cheaper than acquiring new customers. Promoters are more involved, love to help you and provide you with useful feedback about your business. 2% increase in customer retention has the same effect as decreasing costs by 10%.
