What are the benefits of trade for producers of goods and services?

It’s simple, suppose I have a soap factory (no matter what), and I spend 10 rubles to make one piece, that is, its cost price is 10 rubles. This amount includes: the cost of raw materials, salaries of employees, rent of premises, the cost of equipment maintenance, marketing, production costs (marriage). But selling it for 10 rubles is not profitable. Therefore, I will sell it for 12 rubles, and I will put 2 rubles in my pocket. These 2 rubles are the benefits for the producers of goods.
