The financial outcome must always be used as one of the metrics that indicate that the company is being successful, that it is reaching its goal. However, it must not be considered in isolation, because there is good revenue and bad revenue.

Bad revenue is all revenue that comes at the expense of the relationship with the customer. For instance, a company that hinders their cancellation process when customers want to cancel or when a company sells something overpriced taking advantage of your needs, such as the price of a bottle of water in a hotel.

Good revenue is all revenue that comes from deals where we can make our customers happy, where they feel we’ve solved their problem. It’s revenue we can build on by getting even more business from loyal customers, who typically recommend our product or service to their friends.

The bad revenue may help the company in the short run; however, in the long run, clients will get tired of this behavior and will seek for alternatives. That is, bad revenue can eventually kill your company in the long run.

It is not possible to differentiate the good from the bad revenue in a financial report, in which all you can see is revenue numbers without any information on client satisfaction. Because of this, it is necessary to listen to your customers, measure their satisfaction, and correlate it with the financial results.

NPS – Net Promoter Score

There are many ways of measuring customer satisfaction. I like a metric called NPS (Net Promoter Score). This metric has come up for the first time in 2003, in a Harvard Business Review article written by Fred Reichheld, a consultant at Bain & Company, a renowned American consultancy company. In 2006, Reichheld wrote a book called The Ultimate Question that had a second edition published in 2011, containing the lessons learned through the years.

NPS is calculated based on a single question you should ask your client:

The NPS main question:

In a scale from 0 to 10, how likely would you tell a friend or colleague about us?

Zero meaning absolutely not, and 10 meaning absolutely yes. People who evaluated from zero to 6 must be classified as detractors, the ones who graded 7 or 8 must be classified as neutral, and the ones who graded 9 or 10 are promoters.

The NPS calculation is very simple, just subtract the detractorsí percentage from the promotersí percentage. The result is a number varying from -100% to 100%. A negative number means that you have more detractors than promoters, and a positive number means the opposite, that is, you have more promoters than detractors.

Of course, it’s better to have more promoters than detractors, mainly if we think about the word of mouth marketing that comes from both detractors or promoters. Aside from talking about your company and services to their friends, the promoters buy more and stay as costumers for longer. That is, they like your product or service, and will always give you ideas and suggestions that are important to your business.

Several companies use NPS to measure their clientsí satisfaction and loyalty. Some examples are Apple, Zappos, Rackspace, Microsoft, Intuit and Facebook.

How often should you measure NPS? Once a year? Every semester? Every month? Every week? The book recommends to measure it every day, continuously. That can be done in the following way: every day you ask the NPS question to clients who are celebrating the X-months or X-years anniversary that day.

For instance, you can ask your clients when they complete 1 month since they have become your clients, then you can pick up some on-boarding issue. You can also ask your 6-months clients and, from thereon, at each 1-year anniversary at the company. This way you can get NPS reports per time the client is your client, then you will know if you are treating well both new and old clients. To check if your NPS is evolving, you take the moving average from the last 30 days.

Closing the loop: from information to action

The big problem here is that a number alone doesn’t solve much. We need to know where to improve, what to do so the promoters continue to promote our company and services, and what motivated the detractors to give us a low score. To get this information, Fred Reichheld recommends to add one more question to the survey:

The NPS second question:

What is the main reason you gave us that grade?

There you go. With these answers in hands, you have what it takes to go from information to action. While reading the comments of the promoters you will understand what motivated them to give you a high score and keep these actions. From the comments of the low scores, you have the first input to take action. It is very important to talk with the detractors to hear more details on their dissatisfaction.

From the moment they see you care, their perception about your company will start to improve. To seek for understanding the detractors’ motivation and act to solve the problems that got them unsatisfied is the only safe way to increase the NPS and, consequently, the loyalty of your clients.

Maybe you are asking yourself when is the time to provide this feedback. The answer is quite simple and direct: the sooner, the better. In his book, Fred Reichheld advises getting in touch with the detractors in a maximum of 48 hours. Speed is important to show you read and care with your client’s feedback.

Tip: internal NPS

An interesting suggestion on the book is to measure the employees’ NPS, that is, in a scale from 0 to 10, how much this employee would recommend your company for a friend to work there. This questionnaire would have to be anonymous to make the employees comfortable while making comments on any problem they have within the company.

Following the path of clients NPS, you can run this NPS by seasons, that is, 1 month, 6 months and each one-year anniversary at the company. This way you will be able to find out if employees had a good company onboarding process, and if they are still motivated after a few years.

So, we saw several types of metrics, began with the conversion funnel, talked about engagement, churn, global and individual financial metrics, revenue churn and the “Holy Grail” of subscription products — the negative churn. Now, we finished the topic talking about the loyalty metric the NPS. In the next article, I’ll make my final considerations on the metrics theme.
