Hello there, @accounts-bluepro. 

Currently, the option to edit the message isn't available for Statements. 

I can see the need of modifying the statements from QuickBooks. I'll take note of your idea to make sure our developers get your feature request. 

 In the meantime, you can submit feedback yourself by going to the gear icon and selecting Feedback.

For future reference, check out relevant topics in our QuickBooks Articles hub. You can search for some pointers and ideas from other users. 

Feel free to message again if you have additional concerns. Take care!
