Problem
Service calls need diagnostic fees to appear automatically on invoices. The fees are not currently applying to these job types.
Solution
Go to Settings > Operations > Job Types.
Find the job type and click Edit next to it.
Click the Default Services tab.
Enter the details for your diagnostic fee service item.
Click Add.
Click Save.
Note: This process works with service items only. Fee items are not supported as default tasks. Use an existing service item like Diagnostic and Travel Fee instead.
