ProTech Shop Manager grew out of Jacob’s real wrenching at Nunez Performances & Repairs — repair and diagnostic work, mobile calls, school-shop hours and long-term project builds. It exists because renting shop software forever felt wrong.
Nunez Performances & Repairs is one working mechanic — Jacob. Performance builds and project cars on one side; brakes-and-diagnostics bread and butter on the other. Real repair, diagnostic, mobile and school-shop work, plus the long-term builds. Every estimate, every parts order, every unpaid invoice is his to chase.
When he went looking for shop software, the options were $150–300 a month, every month, forever — with his customers' data on someone else's cloud. The alternative was the old way: paper estimates, totals in his head, and a box of receipts that never quite matched the bank.
So he built his own. One price. Runs on his machine. Estimates, vehicle records, parts, payments and long-term builds in one place — no monthly bill. ProTech Shop Manager is that tool, cleaned up so any shop can run on it too.
"I priced the big platforms and couldn't justify renting software forever. So I built what I actually needed — pay once, runs on my machine, and the data is mine."
— Jacob, owner, Nunez Performances & RepairsThe dyno tools aren't there because every shop has rollers — they're there because Jacob wants the path into performance work to be shorter. If you're a tech going out on your own, a tuner picking up customers, or a small shop adding builds to daily repair work, this is meant to be the small, easy base you start from.
Import a pull CSV (Virtual Dyno, Dynojet, Mustang Dyno…) and get the real HP/torque curve with peaks marked. Before/after bars from your baseline and final figures.
Print a clean baseline/final/gain sheet with your shop name across the top — the paper customers pin up in the garage.
Good/Better/Best estimates fit staged builds naturally — Stage 1/2/3 with prices and what's included, on one printable sheet.
Engine code, induction, drivetrain and transmission live on the job card, with real vehicle photos and a specs library that fills itself in.
The builds pay the passion; the brake jobs pay the rent. Both live in the same ledger: estimates and invoices, VIN decode and recalls, scheduling with Google Calendar, inventory, P&L and tax report, tire hotel.
