Thanks for reaching out to the Community, AOK2022. I'm here to lend a hand.
You may contact Mosaic support to check if they have ways to import the time from their software into QuickBooks Desktop.
Otherwise, you may look for an importer tool that lets you do this. I suggest visiting our QuickBooks Apps website. From there, you can find apps integrated with the QuickBooks program. Please visit this page: Apps for QuickBooks Desktop.
Let me know if you have further questions or concerns. I will be here every step of the way. Take care!
