If we do an estimate, does it become part of our revenue or not until it is converted to an invoice?

Hey there, lyoung-walstenma.

Thanks for turning to the Community for support. Since an estimate is used to create a quote, it doesn't become part of income until it is converted to an invoice. Here's a guide on how to create and send estimates in QuickBooks Online. 

Please feel free to reach back out if you have any other questions.
