  • For each task, compute your real numbers from those invoices: average tech hours, actual materials cost, and how often it came back as a callback.

  • The rate that felt generous as a wage is a loss as a business, because the business pays for the van, the insurance, the code updates, the callbacks, and the unbillable hours between jobs.
