How to make an app for a car garage

A busy garage has six or eight cars on the floor, each with a different job, parts waiting and an owner asking when it will be ready. An app keeps a job card for each car, the estimate the owner agreed to, the parts used, and every past visit by car number.

Updated 2026-11-09

Who uses the app

The owner and the service advisor at the counter; mechanics too if they update jobs from their own phones. When more than one phone is used, connect your own Supabase database so everyone sees the same job cards.

The screens a car garage app needs

Cars in the garage: Every open job card by car number, with the status: waiting, estimate sent, approved, in work, waiting for parts, ready
Job card: Car number, model, km reading, the owner's complaint, work to do, the mechanic, photos attached and the promised date
Estimate: Parts and labour with prices; send it on WhatsApp and mark it approved when the owner says yes
Car history: Search by car number or phone; every past visit with the km, work done and the bill
Bills: Bills with parts and labour separated, paid and pending, as PDFs
Service due: Cars whose next service date or km is near, with a WhatsApp reminder button

Features worth asking for

Search by car number to open the car's full history in one tap
An estimate PDF the owner can see on WhatsApp before any work starts
A 'car ready' WhatsApp button with the bill amount filled in
Photos of worn parts or damage attached to the job card
Mechanic-wise list of jobs done this month
A Pay via UPI button and your UPI QR on the bill screen
Next service due by date or km, added when a bill is closed

Where the data lives

If only the counter phone uses it, the data can stay on that phone. If mechanics update job cards from their own phones, connect your own Supabase database from the chat; to collect payments by card or UPI inside the app, connect your Razorpay account as well.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Cars in the garage, Job card, Estimate, Car history, Bills.
Describe it to AppCub. Paste the request below, changed to your own business and details.
Check the plan. AppCub shows the screens and features it will build. Change them in the chat until they are right; seeing the plan is free.
Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
Share it. Share it as a web link, an APK file, or publish it on Google Play from your own developer account.

Copy this request, change the details to match your car garage, and paste it into AppCub:

Make an app for my car garage, Patil Motor Works in Kolhapur. Screens: cars in the garage, job card, estimate, car history, bills and service due. A job card has car number, model, km reading, owner name and phone, complaint, work list, mechanic, photos and promised date, with a status from waiting to ready. Estimates list parts and labour and are sent on WhatsApp as a PDF. Bills separate parts and labour and show my UPI QR. When a bill is closed, set the next service at 10,000 km or 6 months. Red and grey colours.

Tips for a car garage app

Use the car number as the main search everywhere; it is what owners and mechanics remember.
Start with job cards, estimates and bills. Add the service due list after a month, once history has built up.
Write down your status steps as they happen on your floor, and give AppCub the same words.
Keep a parts list with your usual prices so estimates take less typing.
Ask for the car-ready and estimate WhatsApp messages in Marathi or Hindi if your customers prefer it.

Good to know

AppCub doesn't connect to diagnostic scanners, parts suppliers' systems or accounting software, and it sends nothing on its own. Estimates and reminders go out when someone taps the WhatsApp button.
AppCub builds Android apps. You can also share the app as a web link that opens on any phone; for the iPhone App Store, AppCub’s team can do it for you.

Questions

Can the app show a car's full repair history?

Yes. Search by car number or the owner's phone and you see every visit with the km, work done, parts and bill.

Can the owner approve an estimate in the app?

The estimate goes to them as a PDF on WhatsApp, and you mark it approved when they reply. For owners to tap approve themselves, they would need sign-in and an online database.

Can mechanics update the job status from their phones?

Yes, once you connect a Supabase database so the counter and the mechanics see the same job cards.

Can the app read the car's fault codes?

No. AppCub doesn't connect to diagnostic scanners or the car itself. Mechanics type in what they found and can attach photos.

Can the app remind owners when the next service is due?

It shows a list of cars due soon with a WhatsApp button that has the message ready. Someone at the garage sends it.

Can I keep track of parts stock in the same app?

Yes, ask for a parts list with quantities that go down when parts are added to a bill. Start simple and add it once job cards are running well.
