In 100 words or more reply to the statement below about negative cash flow

I agree that usually the first year of a new company will experience negative cash flow because of the amount of money being invested in the inventory, rent and bills, and also advertisement. New business owners should have enough money save up to pay a whole years rent just for security purpose so they don’t fall into debt. I think a good year is reasonable period to have negative cash flow. After two, it should be positive if the business is right.
