In business, profits always come with costs.
For instance, if you own a homemade ham business, you need to spend for the raw materials (raw meat, different spices, and packaging) and for the marketing of your homemade ham (renting a stall in the meat section of a market) before you will be able to receive your profits out of the products that you have sold. In other words, if you will not spend initially on something, there is no chance that you will generate any profits later on.
