The service of a retailer is considered a part of production because it plays a critical role in making finished goods available to consumers. Retailers provide the necessary link between producers and consumers by purchasing goods from manufacturers and making them available for purchase by end-users. Without retailers, finished goods would not be able to reach the intended consumers, which would disrupt the entire production process. Furthermore, retailers also help to increase consumers' standard of living by providing them with access to a wide variety of goods and services. Hence, the service of a retailer is an integral part of the production process.
