The tools I built for my own firm, handed over free. Pricing, scope, qualifying clients, the technical stuff nobody teaches you. No fluff, no funnel gymnastics.
Twenty minutes with your own numbers. Revenue, overhead, and where the money is actually leaking. You'll know within a page whether you're running a business or an expensive job.
Stop guessing at your margins. Cost, freight, receiving, your hours — it tells you what the number has to be for the job to be worth doing.
