WrenchStrike: Mechanic Invoice

The invoicing app built for mobile mechanics and one-bay shops.

Write a professional estimate in the driveway, get it approved, and send an invoice that looks like it came from a real shop system — your logo, warranty, and signature on the paper.

Works offline, backs up to your iCloud automatically, and keeps your Schedule C ready for tax season.

SCAN THE VIN, SKIP THE TYPING

Point your camera at the door-jamb barcode and the year, make, model, and engine fill themselves in — free. Or pick from a list. Or type it. Your call.

ESTIMATES THAT BECOME INVOICES

Write an estimate at the car, tap once to approve, and it turns into an invoice. No re-typing. Track every job from estimate to paid.

TAX DONE RIGHT

Set your state's rate once. Parts get taxed, labor doesn't — automatically. The math is always right, so your books are always clean.

GET PAID YOUR WAY

Your Venmo, Cash App, and Zelle links ride on every invoice. Take a deposit, log a partial payment, watch the balance. Get paid before you leave the driveway.

READY FOR TAX SEASON

A running Schedule C summary — income, parts, expenses — ready to hand your accountant every April. Look back at any year.

BUILT FOR A PHONE IN A GLOVE

Big buttons. Call or text a customer from their card. Attach before-and-after photos. Collect a signature right on the glass. Every customer and every vehicle, on file.

WORKS ANYWHERE, OWNED BY YOU

No accounts. No login. Works with no signal in a dead parking garage. Everything lives on your phone and backs up to your own iCloud — lose your phone, restore in one tap.

Your first 5 jobs are free. After that, WrenchStrike Pro is $12.99/month for unlimited jobs — and everything you already made stays yours forever.

WrenchStrike helps you prepare invoices and tax summaries. It does not provide tax, legal, or accounting advice.
