Chapter 1 introduces a wide range of foundational accounting terms. An entity is a uniquely identifiable business enterprise for which an accounting system is devised. A transaction is any event involving an exchange of value between two or more entities. Assets are economic resources of the enterprise expressed in monetary terms, classified as current and non-current. Liabilities are obligations the enterprise must settle in the future, also classified as current and non-current. Capital is the amount invested by the owner, treated as an obligation of the business.
Sales represent total revenues from goods or services provided to customers. Revenues are amounts earned from selling products or providing services including commission, interest, dividends, and rent received. Expenses are costs incurred in earning revenue; expenditure whose benefit lasts beyond a year is capital expenditure, while short-term benefit expenditure is revenue expenditure. Profit is the excess of revenues over expenses; a gain arises from incidental transactions like sale of fixed assets. Loss is the excess of expenses over revenues or money lost without benefit. Discount may be trade discount (on list price at sale) or cash discount (incentive for prompt payment). Other key terms include voucher, goods, drawings, purchases, stock, debtors, and creditors.
