Talk with several enterprises about centralized procurement, and it will be rolled out. It turns out that the purchasing department is not only an expenditure department, but also a profit department!

In my impression, the purchasing department is responsible for finding good products and then buying them in buy buy. How can we make money?

The first thought is to save costs, which is equivalent to making money, but this is only one aspect.

Another way is to speculate in futures! For example, seasonal products can be bought at low prices and sold at high prices, and they can also make a profit in the middle! But there is a premise that this product can be digested by itself, otherwise it will be a risk if it cannot be sold!
