Selling products used to be the standard way of doing business. Traditionally, it is left to the user to transform the purchase of a product into something that fulfils effectively a final-user need. Today, two streams of research – business management and sustainability – normally with very distinct perspectives on the world, have surprisingly converged to form a common conclusion: selling products is old-fashioned business. Companies should switch their focus to selling need fulfilment, satisfaction, or experiences. Or, in other words, selling integrated solutions or product-services.
