Operating system · Automotive

Open your repair shop with the numbers a lender will actually approve — and the daily disciplines that keep it profitable.

A banker-grade business plan, an editable financial model, and 17 operations playbooks built specifically for the independent, owner-operated general repair shop. Most techs who go out on their own can fix anything but have never set a door rate, built a parts matrix, or shown a lender a real debt-service-coverage ratio — this is the business wrapper around the wrench, with the auto-repair economics done right (technician labor sits in COGS, so the honest gross margin is ~45%, not the inflated 80% a generic template shows).

What's inside

The plan's regulatory and market spine, mapped for this trade: state Automotive Repair Dealer registration and the written-estimate-before-authorization law (e.g. California BAR, BPC §9884.9), EPA Section 609 MVAC refrigerant certification (40 CFR 82) and RCRA used-oil handling (40 CFR 279), Magnuson-Moss on aftermarket parts, garage & garagekeepers insurance, and the program-group nationwide 24-month/24,000-mile parts-and-labor warranty (NAPA AutoCare, TechNet) — riding a fleet that now averages 12.6 years old into a $400B+ aftermarket.

An editable financial model with the real levers: effective labor rate vs. door rate, the tiered parts matrix, ARO × car count, and a materials-and-labor cost structure that reconciles parts GP (~47%) and labor GP (~43%) to a defensible 45% blended margin — plus a break-even car count and a 3-year pro-forma with a computed DSCR a lender underwrites to. Change the opening run-rate, growth, margin, advisor cost, or owner draw and the whole projection recomputes.

17 playbooks that run the shop day to day: the write-up → multi-point/digital inspection → written estimate → recorded authorization discipline, the MPI-driven service-advisor sales process that grows ARO honestly, the first-call parts-supplier decision, the comeback-rate quality loop, technician productivity/efficiency scorecards, environmental and refrigerant compliance, and the trigger for hiring your first dedicated service advisor.
