# How do I add automatic diagnostic fees to specific job types?

## Problem

Service calls need diagnostic fees to appear automatically on invoices. The fees are not currently applying to these job types.

## Solution

1. Go to **Settings > Operations > Job Types**.
2. Find the job type and click **Edit** next to it.
3. Click the **Default Services** tab.
4. Enter the details for your diagnostic fee service item.
5. Click **Add**.
6. Click **Save**.

> [!NOTE]
> **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.
