PROCEDURE:

1. Open QuickBooks.
2. Select Lists > Template.
3. Right-click on all non-used invoices and select Make Template Inactive (you should have only one active invoice template).
4. Go to Invoices and verify the desired template is the only one that is active.

Note: When you make a template inactive, you can no longer use that template when creating an invoice. To make a template active again, open the Templates list and mark the checkbox next to “Include inactive” (this makes all of your inactive templates visible). Right-click the template you want to make active again and select Make Template Active.
