The document discusses the different sources of finance for a business, separating them into internal vs external sources, as well as short-term vs long-term sources. Internally, businesses can generate finance through day-to-day sales, loans from suppliers, reducing stock levels, and selling surplus assets. Externally, finance comes from banks, investors, and the government. Short-term finance covers daily operations and is paid back quickly, while long-term finance funds larger projects but is paid back over longer periods and is riskier.
