Thanks for sharing your concern here in the Community, @JonD777.

I can walk you through on how to add a template to your invoice. This way, you'll have an option to select which of them are you going to use. Let me show you how:

1. Go to Edit and select Preferences.
2. Click Send Forms.
3. Select Company Preferences.
4. Click Add Template or the Edit button, then edit the default customer message.
5. Select Save.

Once done, you can select the template you want to use when sending an invoice to your customers.

You can also run the Open Invoices report to check for pending invoices that you need to send to your customers. Here's how:

1. Go to Reports and select Customers & Receivables.
2. Click Open Invoices. (You can also Customize this report to easily locate a specific open invoices.)

You can always post here if you have more questions about modifying your invoices or templates. QuickBooks Community is always ready to provide you assistance.
