Marketing a product and marketing a service both needs a different approach. While selling a product, we use the 4Ps of marketing, i.e. Product, Price, Place, and Promotion. But, when a service is to be offered, apart from the 4P’s, 3 more Ps are to be taken care of, i.e. People, Process, and Physical evidence. Thus, both require different forms of strategies to promote the overall sale.
