I understand how the ability to change or remove the default message for remittance advice is beneficial to your business, @Karen LL.

 At this time, this option is unavailable in QBO. I recommend manually changing the information upon sending the transaction within QuickBooks Online.

 Please know that we will take note of this feature to get added in the future update.

In the meantime, I want you to be updated with the recent happenings and future developments of QuickBooks Online by visiting our QuickBooks Blog.

Please know that you can tap my shoulder anytime you have additional questions. Stay safe. Thanks!
