Customer Service: Customer service is the provision of service to customers before, during and after a purchase. The perception of success of such interactions is dependent on employees "who can adjust themselves to the personality of the guest". Customer service concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization or may proactively interview customers for feedback. From the point of view of an overall sales process engineering effort, customer service plays an important role in an organization's ability to generate income and revenue. From that perspective, customer service should be included as part of an overall approach to systematic improvement. One good customer service experience can change the entire perception a customer holds towards the organization.

Medical Billing: Medical billing is a payment practice within the United States health system. The process involves a healthcare provider submitting, following up on, and appealing claims with health insurance companies in order to receive payment for services rendered; such as testing, treatments, and procedures. The same process is used for most insurance companies, whether they are private companies or government sponsored programs: Medical coding reports what the diagnosis and treatment were, and prices are applied accordingly. Medical billers are encouraged, but not required by law, to become certified by taking an exam such as the CMRS Exam, RHIA Exam, CPB Exam and others. Certification schools are intended to provide a theoretical grounding for students entering the medical billing field. Some community colleges in the United States offer certificates, or even associate degrees, in the field. Those seeking advancement may be cross-trained in medical coding or transcription or auditing, and may earn a bachelor's or graduate degree in medical information science and technology.
