I appreciate you getting back to us and providing clarification on your concern, @GeorgeMacD.
Allow me to share information about adding other fields within the body of the email of an invoice.
At this time, you can only select the fields showing from the drop-down when customizing email messages. Thus, adding custom fields within the body of the email isn't available.
I can see that this option would help you personalise your email messages by adding custom fields. While this feature isn't available, I suggest submitting feedback directly to our product engineers. This way, they can review your request and add it to the future update. To submit feedback, you can go to the Gear icon and select Feedback. Then, enter your suggestion and click Submit.
You may also want to view the status of your sales transactions in your QuickBooks Online. You can go to the Sales menu and select All Sales.
We're always here to listen if you have concerns regarding other features. You're welcome to post again or leave a reply below.
