Hello Trish,
Welcome to the QuickBooks Community. I'll be happy to provide the info you need so you can get back to doing what you enjoy the most.
In order to successfully transfer your data from Sage 50 to QB Desktop, I recommend using a third-part data migration app that you can search for on our app store deskop.apps.com. I suggest choosing an ap that suits your business needs based on the app description and the reviews. The other option is to manually transferring your data by importing Excel files from Sage 50 to QuickBooks. Here's a helpful article that shows you how to: Import and export data in QuickBooks Desktop.
Let me know if this info helps. I'll be one message away in case you have other questions. Otherwise, I wish you a great rest of the day!
