Yes, it is compatible, @billhdz. Let me provide further details about this below.

Intuit released updates in 2023 for QuickBooks Desktop (QBDT) for Mac 2021, ensuring compatibility with macOS Sonoma. If you have installed QuickBooks Mac 2021 R13.3 or any subsequent release, you should be able to run the program smoothly on Sonoma. For optimal performance and to mitigate any potential software conflicts with your current OS, I highly recommend consulting an IT professional.

You can find more details about system specifications for QBDT for Mac 2021 by visiting this article: System requirements for QuickBooks Desktop for Mac 2021.
