How do I see all invoice information on print/preview mode?

Hi cathy-indeygo-co,

Welcome to the QuickBooks Community. It's a fantastic way to get answers to your questions. QuickBooks Online allows you to view your invoices before you send them so you can be confident with what you're sending. When you click the Print or Preview, a window should pop up with the preview in it. If you don't see it, check your security settings to see if you have a pop-up blocker on. Here's a link that'll walk you through how to check this: How to check for pop-up blockers.

If you have any other questions, reach back out. Have a wonderful weekend!
