Difference between selling cost and product cost is that the latter is is incurred to manufacture a product and provide it to the consumer whereas selling cost includes those incurred to alter, change or create the demand of a product. Hence cost of production includes manufacturing cost, handling, and transportation, storing and delivering cost.
It includes all the expenses which must be met to provide the product or service, transport it o buyer and put it into his hands to satisfy his wants and on the other hand selling cost includes advertising in its various forms, expense of sales department and sales agencies, window displays and other displays of various kinds. The costs made to adapt the product to the demand are the cost of production and costs which are made to adapt the demand to the product is selling cost. It should be taken care that distinction between product and selling cost cannot always be made distinctive as in some cases it could not be said whether product is made to adapt the demand or vice versa. For example cost on attractive packaging could not be segregated into product or selling cost.
