The lack of this feature almost cost me $70. I made an invoice for 2.7 hours and the invoice said it was for $270.00 as soon as I hit send to client it cam back and said your $200.00 invoice has been sent.

Essential - a major missing

I'd love to be able to preview the invoice before sending. The ability to add a link to the invoice in an email to the client would be great to. (In the example of a project kickoff where I send over the agreement + deposit details, it'd be nice to send one email from my inbox vs one email from Flywheel + another from my inbox.)
