You can buy six different businesses (Car Wash, Clothing Store, Grocery Store, Gun Store, Pharmacy, Hardware Store). Each business comes with different products you can buy to sell.

When you buy a business, you will unlock products you can sell in that business. You will need to buy some of those products for your customers. The max stock you can buy is 1K on each of the products you have.

Buying a business will also unlock the ability to manage the price of the products for the business. Each product will have a certain price range you can set it to. Buy setting it to that price is what you get paid. Each day in the game a market price will change. This shows what the best price is to sell that item for. Buy setting it to the market price you get the ability to have a better chance at getting customers to buy your items. But you don't have to set it to that price. The Lowest price you can sell an item for is what you pay for the item (So if you have it on the lowest price you wont make any money off that product).

Each business will cost a certain amount to your utility bill every day (This could be for power or water or anything else). You will also have taxes that you will need to pay. Taxes are 10% of your income that you make off your businesses. For both utility and taxes if you reach $100K in taxes owed you will need to restart your progress. Your max money you can have is 2 billion and can be changed in the future.
