Hi there! Thanks so much for reaching out!
I would verify that your TSheets and QuickBooks accounts are connected properly. You can do that by clicking on the QuickBooks tab at the top right of your TSheets page and then check to see if it's "Connected." If it is connected, try clicking on the "Import" function of that same tab.
Please let us know if that doesn't resolve this issue and we'll be more than happy to help troubleshoot!
