Product Cost Price (with the costs of purchasing)

Some customers care about the raw price of the product, calculating other costs as a different cost or expense.
However, when a customer of mine rightfully makes a purchase, he has many costs such as shipping, travel costs, customs, customs procedures and taxes for 4 different products, and he thinks that all product items should be equally distributed over the quantities.

Is there any computable cost work or setting for the actual selling price of the product?
