GarageCodex is a complete shop management app for independent auto repair shops and mobile mechanics; work orders, estimates, invoices, customers, and payments in one place, running entirely on your own device. No monthly fee. No account. No internet required.

RUN THE SHOP, NOT THE SOFTWARE
• Check in a customer, their vehicle, and the job in under a minute
• Scan the VIN barcode to fill in year, make, model, and engine automatically
• Work orders track jobs, labor, parts, and status from estimate through paid
• Reusable Labor Book entries drop common jobs onto a work order in one tap
• Labor timers record actual wrench time per job
• Look up part prices at O'Reilly, AutoZone, NAPA, Advance, and Amazon without retyping the vehicle

PAPERWORK YOUR CUSTOMERS WILL TRUST
• Professional PDF estimates and invoices, ready to print, text, or email
• Customer approval signatures and completed-work signatures captured on screen
• Multi-point digital inspection (DVI) with photos, color-coded on the invoice
• Record payments, track balances, and watch estimates advance to paid automatically

KNOW YOUR NUMBERS
• Dashboard with money collected, outstanding balances, parts margin, and effective labor rate
• Expense logging with receipt photos
• Year-end tax summary you can hand to your accountant, plus CSV export of everything

BUILT FOR MOBILE MECHANICS TOO
• Mobile Mechanic mode adds service addresses, one-tap navigation, and service-call fees
• GPS trip tracking records real miles and travel time for every job — started and stopped by you, with a visible notification while recording
• Mileage log export for tax time

YOUR DATA IS YOURS
Everything lives on your device, so the app works in a concrete-block shop bay or a customer's driveway with no signal. Automatic local backups protect your records, and you can optionally back up to your own Google Drive; your account, your file, invisible to us. We run no servers and never see your data.

ONE PRICE, FOREVER
Try it free with up to 3 customers and 3 work orders; every core feature included. One single purchase unlocks unlimited use, permanently. No subscription. No per-invoice fees. No credits. The price you pay is the last price you pay.

Built for independent shops, mobile mechanics, and side-hustle wrenchers who want their shop records to belong to them.
