There are several ways to add labor to your projects. You can add labor values to each line item, add it as a factor, or create separate labor line items, unattached from any other equipment.
To do this, just go to the Builder and click "+Add Item" then click "+Create New Item"
Then name your item (ex: "Consulting Labor" or "Installation") and leave all the cost/price fields blank. Add values in the labor section (hours, minutes, or price) and click "Add and Close."
Now you'll have a line item that only includes labor, no equipment.
Let us know if you have any questions about that!
