How to make an app for a car wash

A car wash sees the same cars again and again, on monthly plans or daily doorstep cleaning in societies. An app keeps each car by its number, the plan it is on, the washes done this month and who has paid, so the cashier and the washers stop relying on a notebook.

Updated 2026-11-09

Who uses the app

The owner and the cashier at the bay, and washers if they mark doorstep cleans. If more than one phone is used, connect a Supabase database so the bay and the washers see the same cars and plans. A customer screen for booking slots also needs that database.

The screens a car wash app needs

Today: Cars washed today with number, car size, package, washer and amount paid, and the day's total
New wash: Type the car number; the owner and car size fill in from past visits, pick the package and the price follows
Monthly plans: Cars on a plan, washes used out of the month's total, and plans ending soon
Society cleaning: Cars in each society by tower and parking slot, the washer assigned and days cleaned this month
Customers: Search by car number or phone, with each car's wash history and a WhatsApp button
Staff: Washers, their attendance and the cars each one washed

Features worth asking for

Search by car number, so a returning car is found in seconds
Prices by car size and package that fill in on their own
Monthly plans with washes left, and a WhatsApp renewal message before a plan ends
Doorstep society cleaning with a tick per car per day and a monthly bill PDF for each owner
Washer-wise count of cars washed for paying incentives
A receipt PDF to share with the car owner

Where the data lives

If only the cashier's phone is used at the bay, the data can stay on it. If washers mark doorstep cleans on their own phones, or owners check their plan, connect your own Supabase database from the chat; for online plan payments add Razorpay, and the money goes to you.

Tips for a car wash app

Use the car number as the main way to find a customer; it is what washers and cashiers remember.
Write your package names and prices exactly as on your board, so the app and the bay agree.
For societies, list cars by tower and parking slot in the order washers walk the basement.
Start with today's washes and monthly plans. Add society cleaning and staff counts in the second week.
Test a busy weekend morning with the app before you stop the paper register.

Questions

Can the app find a car by its number?

Yes. Ask for car number as the search field, and the owner, car size and past washes come up when you type it.

Can the app run monthly wash plans?

Yes. Ask for plans with a number of washes or days, and the app shows washes left and plans ending soon, with a WhatsApp renewal message.

Can washers mark daily cleaning in a society?

Yes, with a tick per car per day. If washers use their own phones, connect a Supabase database so the owner sees the same record.

Can society residents pay their monthly bill in the app?

Yes, with a payment button on your own Razorpay account after connecting Razorpay and Supabase in the chat. The money goes to your account.

Can I count how many cars each washer did?

Yes. Each wash records the washer, and the staff screen shows a count by day or month, useful for incentives.

Can customers see when their car is ready?

Not live. The cashier can tap a WhatsApp button with a ready message to tell the owner the car is done.
