Fees earned from providing services and the amounts of merchandise sold. Under the accrual basis of accounting, revenues are recorded at the time of delivering the service or the merchandise, even if cash is not received at the time of delivery. Often the term income is used instead of revenues.

Examples of revenue accounts include: Sales, Service Revenues, Fees Earned, Interest Revenue, Interest Income. Revenue accounts are credited when services are performed/billed and therefore will usually have credit balances. At the time that a revenue account is credited, the account debited might be Cash, Accounts Receivable, or Unearned Revenue depending if cash was received at the time of the service, if the customer was billed at the time of the service and will pay later, or if the customer had paid in advance of the service being performed.

If the revenues earned are a main activity of the business, they are considered to be operating revenues. If the revenues come from a secondary activity, they are considered to be nonoperating revenues. For example, interest earned by a manufacturer on its investments is a nonoperating revenue. Interest earned by a bank is considered to be part of operating revenues. To learn more, see Explanation of Income Statement.
