If you are not using "QuickBooks Online Payroll" when exporting your employees' hours from AccountLinx, you will see that your employees' overtime/double time hours from Arcoro Time will be considered regular hours in QuickBooks Online. This is due to a limitation in QuickBooks Online and requires "QuickBooks Online Payroll" for AccountLinx to be able to specify the "Pay Type".
In these situations, you must manually adjust your employees' weekly timesheet in QuickBooks Online to reflect the appropriate type of hours.
