Web AppEnglish learners sometimes confuse the words “consumer” and “customer”. Although they look similar and the distinction is not important sometimes, they refer to different concepts:
consumer = the final user of services and goods
For example, when you go to a supermarket and buy groceries, you are a customer. When you later come home and eat the food you bought, you assume the role of a consumer.
Hence we have terms like customer service, i.e. the department that takes care of your shopping experience and helps you solve possible problems, and consumer electronics, which refers to devices intended for sale to their final users, e.g. laptops or cameras, as opposed to electronics sold as parts for assembly or to businesses, such as microchips or cash registers.
Just remember: If you speak about the process of buying something or paying for something, use the word “customer”, and if you speak about consumption or use, the appropriate word is “consumer”.
