Whether you are editing a surcharge or adding a new surcharge, the same pop-up window will appear to edit or create a surcharge.
Enter a code name, description, select whether the surcharge will be calculated based on labor, parts, or parts & labor, then enter the percent to be charged.
Enter minimum and maximum amounts if you want to set a flat rate surcharge or prevent it from being too high on expensive repair orders.
Check Taxable if taxes should be applied to the surcharge.

If specific surcharges need be charged on specific
parts, or specific parts should not incur a surcharge, you can add overrides
under Part Surcharge Overrides.
Click on Add
Part Surcharge Override.
Select the surcharge code, enter the part number,
then enter either a percent or a flat rate to be applied to the specific
part. Click OK to save.
