Thank you for getting back to us, @pbb2.

For now, the option to change the default email messages for payment receipts is unavailable in QuickBooks Online (QBO). You have to manually edit its info before sending it to your customers.

I can see how this option would be helpful for you and your business. Therefore, let me take note of this as a suggestion to improve your QuickBooks experience.

Additionally, you can send your own feedback to our Product Development team. This way, they can review your request to help improve your experience in QBO.

Here's how:
 

1. Click the Gear icon at the top and select Feedback.
2. Enter your comments or product suggestions.
3. Select Next to submit.

In the meantime, I recommend visiting our Firm of the Future site. This is where we share recent happenings and future developments, such as updates to newly added features.

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response.
