Fire Your SaaS.
Generic software-"as-a-service" charges $588 to $1,788 a year, forever, to do math a good spreadsheet does better. These are purpose-built back-office systems in a single Excel file you own — price book, quote machine, customer & job history, profit dashboard. Built for your trade, not everyone's. $75. Once.
Trade Pricing & Job-Costing Systems
Each one is a mini CRM plus a live bill-of-materials tracker for a shop of one. Blue cells are your live inputs; gray cells calculate loaded costs, fee stacks, and profit guardrails.
Heating & Air — 1–2 Truck Shops

Every Purchase Includes
A personal setup check-in — 15 minutes on a screen share where we put your real rates, markups and assemblies in and make sure the output matches how you actually work — and the next revision of your engine free.
14-Day Math Guarantee: if a calculation fails to perform as demonstrated and we can't fix it within 48 hours — full refund.
I Build These Custom.
Detailing, lawn care, cleaning, food trucks, churches and non-profits, childcare, specialty fabrication — the four engines above prove the architecture. If your pricing lives in your head or a spreadsheet nobody's allowed to touch, I build the engine around how you actually work.
