Thanks for posting to the Community, @kim-s.

Yes, I know how beneficial it is to get the option for replying to a person for estimates, and a separate person for invoices in QuickBooks Online (QBO).

Please know that I'm taking note of this one. In the meantime, you can visit our QuickBooks blog site to see the freshest feature updates and product enhancements.

Additionally, when you want to learn more about QBO, you can navigate the tabs above to search for articles, topics, and training videos.

If you have more questions about QuickBooks, feel free to post a comment below. I'll reply as fast as I can. Take care and more power to your business!
