If your firm requires the billing partner to review all invoices before they
are sent to customers, you can create a pending invoice. QuickBooks doesn't
show the pending invoice in registers until you mark it as a final invoice.
To do this task
Go to the Customers menu and click Create
Invoices. Enter the customer name and charges.
In the Customer Message field, type Pending.
Go to the Edit menu and click Mark
Invoice As Pending. QuickBooks displays the word "Pending"
on the onscreen invoice (not on the printed form).
Print the pending invoice for the billing partner's review.
When the invoice has been approved, go to the Edit
menu and click Mark Invoice As Final.
Remove the word Pending from the Customer
