Adjusting entries are journal entries recorded at the end of an accounting period to adjust income and expense accounts so that they comply with the accrual concept of accounting. Their main purpose is to match incomes and expenses to appropriate accounting periods. The transactions which are recorded using adjusting entries are not spontaneous but are spread over a period of time. Not all journal entries recorded at the end of an accounting period are adjusting entries. For example, an entry to record a purchase on the last day of a period is not an adjusting entry. An adjusting entry always involves either income or expense account.
