- Open QuickBooks.
- Select Lists > Template.
- Right-click on all non-used invoices and select Make Template Inactive (you should have only one active invoice template).
- 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.
