When I create an Estimate, it shows as an Invoice in the email and says balance due. The actual attachment shows as an Estimate.

I can see the inconvenience this has caused you, @edcicone.

As of now, we have an ongoing investigation (INV-100722) regarding the issue upon viewing the estimates sent to the email it shows View Invoice even though it is an estimate and the balance due. With this, I suggest reaching out to our QuickBooks Online Support team so you'll be added to the list of affected users to ensure you'll get an update about the resolution status.
