Hi there, @accounts-2upc. Let's work this out so you get rid of the Review and Pay button when emailing an invoice in QuickBooks Online (QBO).
Before anything else, I'd like to thank you for taking the time to perform the recommendation provided by my colleagues above. Since you've mentioned that you don't have any payment options set up, know that you only have three options to get rid of the said button.
You can select HTML, Plain text, or Online invoice in the Online delivery section. However, for HTML and Plain text options, when you email an invoice, you'll directly see the details your invoice contains. Now, if you choose Online invoice, you'll have the Print and Save button. After you've set it up, please be aware that it'll take effect the next time you email an invoice. That said, it won't affect invoices you've already sent to your customers in QBO.
If you don't want the options I've mentioned, I recommend sending a feature request to our Product Development Team. This way, they'll see your feedback and consider adding it to the next product update. I'll gladly input the steps below. To begin, here's how:
