Customer attrition, also known as customer churn or customer turnover, refers to the loss of customers that were previously active and engaged with a business. It is a natural occurrence in any business, but excessive attrition can lead to significant revenue loss and damage to the brand's reputation. Synonyms for customer attrition include customer defection, customer abandonment, customer loss, and customer disengagement. These terms depict the dissatisfaction or disinterest shown by customers towards a business resulting in their decision to go elsewhere. To reduce customer attrition, businesses need to focus on providing exceptional customer service and continuously addressing customer needs and concerns.
