The document provides advice for two new hairdressers starting a business on internal and external sources of finance available as business partners. Internal sources include using their own savings which provides flexibility but is limited in amount, or using one partner's savings which helps financially but relies on that partner. Business profits can also be used, with the distinction that gross profits are not actual profits while net profits are actual retained earnings after expenses. External sources include bank overdrafts which provide flexibility in borrowing only what is needed and are reliable as long as terms are met.
