How do I get all the data from my servicem8 account onto my quick books account?

Hi -acedelec-com,

QuickBooks Online (QBO) depends on the data sent from the third-party application. You may have to check your app settings to ensure it is mapped correctly to be imported to QBO. 

You can also reach with the third-party app's customer support on how to resolve the integration issue you have with QuickBooks and the app. They'll be the best team to help check your app settings.

Post again in the Community if there's anything else I can help you with QBO. I'm here to assist you.
