Hello there, MMHOANC.

I can see how easier it would be to be able to review messages that were sent. That said, I'd suggest sending feedback to our developers. They'll review your suggestion by going to the Gear icon and then selecting Feedback.

ou can track feature requests through the QuickBooks Online Feature Requests website.

You can also check this link that can guide you on how to modify your sales form: Customize invoices, estimates, and sales receipts in QuickBooks Online.

I'll be around whenever you have concerns with creating transactions.
