If you have admin permissions, you can view and edit the 16 different Skill Levels and their Hourly Labor Rates from the Labor Rates for Skill Levels screen within the Admin Tools.
Each Skill Level along with its Hourly Labor Rate can be dedicated to specific jobs. For example, if your location has different rates for your body shop or transmission work, you can add skill levels for both.
Users can then enter line item operations from estimates and directly apply the correct Skill Level along with its Hourly Labor Rate for that line item.
