How can I include my labor costs?
Define an “additive” called labor_hour or something similar, and input your hourly rate as the “Purchase Price” and a quantity of 1.
Use the weightless “item” unit. Now you can include as many “items” of labor_hours as you want in a recipe to see the total cost.
If you have SoapMaker Professional, you can even track your total hours worked along with your inventory.
Add a “Labor budget” to your database by using the Add Stock feature in the Ingredients dialog. Or if you just want the Labor for cost reasons, you can simply ignore the “low labor” warnings whenever you make a batch, and the Labor item in your inventory will go negative with no ill-effects.
