QuickBooks Online's API does not currently allow pay types to be assigned automatically.
To indicate your overtime hours, we send the hours into QBO with an attached note stating that the hours are overtime. This OT indicator is based on the settings you have selected in Pay Period/Overtime within BusyBusy.
Instructions:
To make the corrections needed for payroll, you’ll need to sign in to QuickBooks Online, click Create (+) and open the Weekly Timesheet.
Locate the entry, review the synced note, and manually select Overtime from the Pay Type dropdown menu before processing payroll.
Given your settings, pay type may or may not appear here. You can select the settings wheel in the top right corner to turn pay types on to view and edit them within the weekly timesheet. Then you are finished!
