I understand how convenient it is for you to choose the basis of accounting period you want to display in your QuickBooks Desktop.

The accounting period in QuickBooks is determined by the accounting method employed. When using the accrual basis, the accounting period is when you enter a transaction, pay, or receive cash. On the other hand, if you operate on a cash basis, the accounting period begins when you receive a payment or pay a bill. Moreover, how the accounting period is displayed is one of the features of the QuickBooks Desktop.
