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 unlocks unlimited jobs: $5.99 per month, or $55.99 per year. Everything you already made stays yours forever.

Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. Manage or cancel your subscription anytime in your App Store account settings.

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