Thanks for joining in this conversation, @amejia. I'm here to share insights and answer all your concerns about single and user mode access in QuickBooks Desktop.
Yes, you can install one license to three different computers. However, each user can only use one at a time.
Should you need to access and use the company file in different computers at the same time, you'll need to have three different licenses and switch to multi-user mode. Read this article: Available features and tasks you can perform in single or multi-user mode.
