The same message is displayed three times in three different ways:

1. Preview before sending the estimate: "Print and Save" button.
2. Preview in email from the client's view: "Review and Pay" button.
3. View from QuickBooks page: button "Accept or Decline".

I've spoken today with Ringo from the Quickbooks help desk and he told me to raise a suggestion here.

I think that the bottom should be the same message every time the client gets confused (it happen to my clients)
