Which icon should be clicked to begin entering an expense in QuickBooks Online?

To begin entering an expense in QuickBooks Online, the appropriate icon to click is the plus icon. This icon serves as the gateway to creating various types of transactions, including expenses, invoices, bills, and more. When you click on the plus icon, a drop-down menu appears, providing options for adding different kinds of activities. Since entering an expense is a key function for managing accounts and tracking spending, the plus icon is designed to facilitate this process efficiently.

The other icons serve different purposes; for instance, the checkmark icon typically represents actions to confirm or save changes, the settings icon generally directs users to configuration options, and the gear icon often leads to account and organizational settings. Thus, selecting the plus icon is the most direct and effective way to initiate the expense entry process in QuickBooks Online.
