Herbein Earns Diamond Award for Service Excellence

Client Satisfaction is a two-way and transparent conversation.  Herbein utilizes a Net Promoter platform which enables us to benchmark against the accounting industry as well as companies in other industries.  

Herbein + Company, Inc. has won the Best of Accounting Diamond Award for providing superior service to their clients for at least five consecutive years. ClearlyRated's Best of Accounting® Award winners are proven industry leaders in service quality based entirely on ratings provided by their clients – and are twice as likely to be satisfied than those who work with non-winning firms.

 Herbein + Company, Inc. Managing Partner David W. Stonesifer, CPA, said, “Herbein team members share the view that our contributions matter – and that is how we help our clients succeed with confidence.  Our team is inspired to be our best and do our best in providing exceptional client service. We are proud and honored to be a ClearlyRated Diamond Award winner, which recognizes our capacity to be agile on behalf of our clients, which has never been more important.”


Herbein + Company, Inc. received satisfaction scores of 9 or 10 out of 10 from 88.5% of its clients, significantly higher than the industry’s average of 43% in 2020. Additionally, Herbein received a Net Promoter® Score (NPS) of 85.2% from clients, significantly higher than the industry's average of 23% in 2020. On the NPS scale, any score above 70 is considered “world-class” – and Herbein is proud to have again earned this world-class Net Promoter Score following one of the most challenging years in history.

Just 22% of the 2021 Best of Accounting winners earned the Diamond Award distinction.

About the Net Promoter Metric

  • A Net Promoter Score is a simple satisfaction metric that is based on the single 11 point scale survey question "how likely are you to recommend XYZ Company to a friend or colleague?" Survey respondents are broken into 3 categories, depending on the score they give:
  • Promoters - respondents who answer a 9 or 10 to the recommend question represent a firm's strongest allies and are most likely to promote the firm to others.
  • Passives - respondents who answer a 7 or 8 to the recommend question are likely satisfied with the firm, but not out actively promoting it to others.
  • Detractors - respondents who answer with a 6 or lower are likely to be un-satisfied and may even be looking to switch to a new firm.
  • The Net Promoter Score is calculated by taking the % of promoters minus the % of detractors. The Net Promoter Score was developed by Bain consultant and author Frederick Reicheld. More information on Net Promoter Score can be found at
