I would love to see an invoice type for my travel business.

I would love to see an invoice type for my travel business where I could put the hotel, airfare, etc and a line where they can accept or reject travel insurance and a line where they can authorize use of the credit card for the transaction.

When it comes to payment authorization, you can enable this option a your payment settings, so you can charge the user later through your payment's gateway dashboard: https://www.jotform.com/help/292-How-to-Enable-Payment-Authorization
