Is it at all possible to print or preview an invoice without it actually been sent to the client?
At the moment the only way to print an invoice is to screenshot it otherwise it applies and mails...
Yes I have used this feature a fair bit in my time as Technical Support for Essentials.
I did not mention using the print function because, as you have suggested in your message that you would like to preview it, as it would be sent to the client, the way to check that with certainty is to use the email feature.
Your original message seemed to suggest that you did not actually want it to be automatically sent through to the client before you had previewed it, which is why my suggestion was one that wouldn't send anything through to the client. The email workaround that I suggested and the print alternative that you have posted above are imperfect workarounds but will let you view the information without it being sent through to your client until you use the 'Resend to Customer' button to actually process it through. If there was a perfect workaround for this, then the suggestion would have been marked 'Already in Product' and closed, as this is not the case I have marked it as 'Under Consideration' so the community can vote on it and we can get an idea for the demand for it so that it can be added in fully at a later date.
I hope this clears up any confusion that you may have on the Ideas Exchange process and my above post.
Kind Regards,
Matthew
