Hello there, @piercetek.

We want to ensure this gets sorted out as soon as possible. That said, can you tell us more about your experience? Have you tried the steps provided by our colleague? Or does the Plain text option not meet your business needs? This way, we can provide you with the correct steps or workaround to help you remove the Review & Pay button when emailing an invoice.

Feel free to visit the Community space or comment below so we can respond right away. Keep safe.
