I'd like to join you here and answer your inquiries about moving to the later version of QuickBooks, midnightlace1.

There's no need to purchase or buy older versions of the software to upgrade your file from 2013 to 2021. I'd like to clarify that suggestions in the earlier responses was to make the update in between versions to avoid data damage using trial licenses.

However, that is no longer necessary since the last update. As shared by other users in this thread, they were able to update the file directly from 2013 to 2021 without any issues. 

However, you can also contact our Technical Support Team just in case you need extra help when doing the update. They will be the one to update your file and make it ready for QuickBooks 2021. 

Here's how to reach out to them:

1. Go to the Help menu and select Contact Us or press F1 on your keyboard.
2. Click Contact Us at the bottom of the screen.
3. Provide a short description of your concern, then click Continue.
4. Select between Chat or Callback.
