We'd want to make sure all details are showing up when the transaction is generated, crewjoy.

I also wanted to ask what have steps you tried so far? Have you created a new template to check if the message would show up. I'm asking these questions because the investigation that was previously mentioned in the old responses has already been closed and resolved. This is to also test if the template you're currently using is the one that's having the issue.

If you haven't tried it yet, follow these steps on how to create a new template:

1. Go to the Gear icon and select Custom form styles. 
2. Click New style in the upper-right hand corner and select Invoice.
3. Proceed to the Content tab and click on the pencils (you’ll see them in white) in the right-hand corner. 
4. Scroll-down to the Message to customer on section and type in your message.
5. Click Done to save the changes. 

After that, create a new invoice and print it to check if the message is now showing up. 

I'd also like to share a couple more articles about customizing sales forms in case you might be interested in using them: 

• Add, Customize, or Remove Logos on Sales Forms 
• Customize Invoices, Estimates, and Sales Receipts in QuickBooks Online 

Don't hesitate to share updates and let me know if the message is now showing up. You can also reach out to us again if you need anything else.
