A simple yet very effective way to gauge how well you are doing in servicing your clients is to ask one simple question: On a scale of 1 to 5, how likely are you to refer my services to your closest business associates, peers, family or friends? The question is known as the Net Promoter Score (NPS) and has been used extensively across many different industries for the past two decades. When I was the VP of Marketing for a regional bank, we added the question to as many customer touch points as we could and reported the monthly average score on our management reports. Financial reports are a trailing indicator for your firm's performance. But the NPS gives you a real time snap shot into how you are perceived by your clients and their willingness to participate in your success.
