How can I edit the 'message to customer' email on statements? I can edit same on invoice, receipt and quote but not on the statement.

I appreciate you chiming in on this thread, SATN. Allow me to share information to ensure you're able to edit the message to customer email on statements.

If you're referring to the Email Body when sending out customer statements, we can edit or add changes from there. Once you're done reviewing them, you can click on Save and Send to open the printable statement form. I've added a screenshot for reference.

Additionally, you can set up default messages for your statements from the Accounts & settings. To do that:

1. Go to the Gear icon and select Accounts and Settings.
2. Click on the Sales tab.
3. From the Messages section, click Edit.
4. Under the Sales form dropdown, choose Statement.
5. Edit the message from the Email message box.
6. Add additional changes and click Save. Then, Done.

However, if you're referring to the Message box directly printed on a statement, I'd recommend sending this relevant request to our product engineers. This way, they'll consider this suggestion and will work on its progress to include them in our future product enhancements.

Here's how to submit feedback:

1. Click on the Gear icon and select Feedback under Profile.
2. Enter and share your feedback or suggestion.
3.  Then, click Next to submit.
