An accounting method where receipts are recorded during the period they are received, and expenses are recorded in the period in which they are actually paid. Cash accounting is one of the two forms of accounting. The other is accrual accounting, where revenue and expenses are recorded when they are incurred. Small businesses often use cash accounting because it is simpler and more straightforward, and it provides a clear picture of how much money the business actually has on hand. Corporations, however, are required to use accrual accounting under generally accepted accounting principles.
