Is there a way to see an invoice, exactly as it will be send to client (not the preview), before sending?

Hi there, 

I'd be happy to assist you from here. It's important to know what your invoice will look like once the customer receives it. Apart from using the print/preview feature, the only other way I can think of would be emailing the invoice yourself instead. When creating the invoice, just make sure to replace the customer email with your email. That way you'll know what the invoice looks like going forward. 

Here's a helpful link which you may find useful https://community.intuit.com/articles/1770326. The link will show you how to add a personal touch to your invoices. Once you've saved that template, you won't have to worry about what it'll look like on the customer's end. Let me know if you have further questions. I'll be here to help.
