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.

Customer Engagement: Customer engagement is a business communication connection between an external stakeholder (consumer) and an organization (company or brand) through various channels of correspondence. This connection can be a reaction, interaction, effect or overall customer experience, which takes place online and offline. The term can also be used to define customer-to-customer correspondence regarding a communication, product, service or brand. However, the latter dissemination originates from a business-to-consumer interaction resonated at a subconscious level. Online customer engagement is qualitatively different from offline engagement as the nature of the customer’s interactions with a brand, company and other customers differ on the internet. Discussion forums or blogs, for example, are spaces where people can communicate and socialise in ways that cannot be replicated by any offline interactive medium. Online customer engagement is a social phenomenon that became mainstream with the wide adoption of the internet in the late 1990s, which has expanded the technical developments in broadband speed, connectivity and social media. These factors enable customer behaviour to regularly engage in online communities revolving, directly or indirectly, around product categories and other consumption topics. This process leads to a customer’s positive engagement with the company or offering, as well as the behaviours associated with different degrees of customer engagement.
