Since the update, when we send an estimate the email says invoice and balance due. Is this an internal adjustment that needs to be made?

It's a known bug. One of many (hundreds?) with the new 'improved' invoices.

I'm here to provide some insights when sending estimates as to why it shows invoice in QuickBooks Online, @carterlandservic.

As per checking, I've found an ongoing investigation (INV-100722) regarding the issue when attempting to send an estimate, but the email states about invoice and balance due.
