I'm here to share some details about the finance charge, sal74.

In QuickBooks Online (QBO), the late fee feature is designed to be applied to invoices based on their original date, rather than the current date. If you need to apply a late fee to an invoice that was created several months ago and your books are closed for that period, it is advisable to create a new invoice in the current period specifically for the late fee amount. This way, you can accurately reflect the late fee in the appropriate accounting period.

Alternatively, you can manually add the late fee to the invoice. You can do this by editing the invoice and adding the late fee as a separate line item.
