Kaplan University Determining Appropriate Services Discussion

Need help with my Accounting question – I’m studying for my class. What  if a client approaches you with an engagement request that you are not  sure your CPA firm provides? Knowing which services are offered and how  they are performed helps to ensure you provide your clients with the  services they need.You  are approached by the Emerald Production Company management to review  and analyze their customer satisfaction trends over the past 5 years.  This assurance service would tell management if their suspicions were  correct in that customer satisfaction has been declining, especially in  the past 2 years. Management currently evaluates customer satisfaction  based on customer retention and sales increases. While management sends  out surveys via mail and email to customers, response rates are very  low. Management does not consider the survey responses to be an accurate  representation of their customer service. In fact, only customers with  negative feedback are the ones who respond.Assuming that your firm can provide this type of service, where would you look to find guidance for this service?What standards would you need to follow?
