Hi, @AllSeasonsCleaning.

Yes, you need to create a back up of your file, then restore it to your second computer to sync the latest QuickBooks data. On the other hand, you may set up a multi-user network so computers on your network can access your company files without doing the backup or restore process. You can check out these links as your guides:

• Set up and install a multi-user network for QuickBooks Desktop
• Open a company file located on a remote computer

On the other hand, if you wish to move your QuickBooks or file to another computer completely, I recommend opening these links for the instructions:

• Move or reinstall QuickBooks Desktop to another computer
• Move your company files to another computer

If you have any other follow-up questions about handling your files in QuickBooks Desktop, let me know by adding a comment below. I'm always here to help. Have a good one!
