Hello there, @AsielCode7.
As of now, it's still not possible to modify default email messages for payment receipts in QuickBooks Online (QBO). Before sending payment receipts to customers, you'll need to edit the information manually.
I suggest sending feedback to our product engineers so they can reassess this matter. They are responsible for determining which features will be added in the future.
To send your request:
- Go to the Gear icon.
- Select Feedback.
- Enter your comments or product suggestions.
- Tap Next to submit.
I'm adding this article here on how to personalize and add specific info to your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.
Post here in the Community if you have further questions on your sales forms and other QBO-related concerns. Our team is available 24/7 to assist you. Stay safe!
