In a corporate structure, ‘sales’ is commonly a grouping that consists of specialists who are employed to sell the product or good which the business offers. These specialists are known as sales agents or salespersons.
Another major difference between them is that sales aim at gaining profits by increasing the number of goods sold. On the other hand, a service aims at building a good relationship with the customer by providing support or guidance based on specialized knowledge. This is done to ensure that the customers are satisfied.
