The main keyword in this text is ‘customer.’ A customer refers to a person or entity that acquires goods or services from a company. They play a vital role in the business environment, establishing connections with companies via transactions. Customers may also be referred to as ‘clients,’ particularly when they obtain customized advice or solutions from a company. The term ‘client’ is derived from Latin, suggesting a tendency to lean or bend towards a company. Customers come in various forms – from final customers who directly purchase products or services, to industrial customers who integrate these products or services into their own offerings. These customers can hold different positions in relation to the business, such as being employers in construction endeavors. Companies often divide their customers into distinct groups, like business owners or final users, to better comprehend and cater to them. The comprehension and handling of customer relationships is a crucial field of research and application in business.
