Intangibility.

Explanation:

One of the biggest differences between marketing a service and a product is the intangibility of the purchase. The consumer can see and touch a product such as a new laptop computer, but he cannot touch or feel the service he hires to fix a computer.

Intangibility in marketing can be defined as the inability of a service taker (customer) to assess the value or benefits to be derived from the use of a service. When compared to a product, services are intangible because they are abstract and as such cannot be touched, seen, heard, tasted, felt or smelled by the senses.

Hence, it requires more quality and degree of competence to market a service than a product.
