How to make an app for a dairy shop

A milk dairy keeps a register for every house: 2 litres daily, 1 extra on Sunday, nothing for three days while they are away, and the rate went up on the 15th. An app does that sum for you, makes each family's month-end bill and shows who has not paid.

Updated 2026-11-09

Who uses the app

The owner, and the milkman who does the rounds. If the milkman marks deliveries on his own phone, or customers mark their own skipped days, connect your own Supabase database so the register is the same for everyone.

The screens a dairy shop app needs

Today's round: Houses in route order with litres and type of milk, and a tick when delivered
Customers: Each family's address, daily quantity, cow or buffalo milk, morning or evening, and phone
Changes: Extra milk, less milk or no milk for a date or a range of dates
Shop sales: Counter sales of milk, curd, paneer and ghee by weight or litre
Rates: Milk and product rates with the date each rate starts
Monthly bills: Each customer's litres, rate and amount for the month, as a PDF to share on WhatsApp
Dues: Who has paid, who owes, and how much is pending from earlier months

Features worth asking for

Daily litres worked out from the usual quantity and the day's changes
Rate changes in the middle of the month handled by date
Morning and evening rounds kept separate
Monthly bill as a PDF, sent with a WhatsApp button
A total of litres needed for tomorrow, so you know how much milk to collect
Dues carried forward month to month
Hindi or Gujarati labels if your milkman prefers them

Where the data lives

If only you use the app, the data can stay on your phone. If the milkman ticks deliveries on his phone or customers mark their own days off, connect your own Supabase database; to take monthly payments online, connect your Razorpay account too.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Today's round, Customers, Changes, Shop sales, Rates.
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 dairy shop, and paste it into AppCub:

Make an app for my milk dairy shop, Jadeja Dairy in Rajkot. Screens: today's round, customers, changes, shop sales, rates, monthly bills and dues. Each customer has a daily quantity of cow or buffalo milk, morning, evening or both. They can take extra, less or no milk on some dates. Rates change by date; buffalo ₹70 and cow ₹60 a litre now. Show tomorrow's total litres. Today's round lists houses in route order with a tick. At month end, make a bill PDF for each customer with a WhatsApp button, and keep unpaid dues carried forward. White and blue colours.

Tips for a dairy shop app

Enter customers in the order of your morning round; it saves time every day.
Give AppCub your exact rule for a rate change in the middle of the month.
Mark skipped and extra days the same evening they are told to you, not at month end.
Check the first month's bills against your paper register before you stop keeping it.
Ask for labels in the language your milkman reads.

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 a dairy app make monthly milk bills?

Yes. It adds up each day's litres after extra and skipped days, multiplies by the rate on each date, and makes a PDF bill for each customer.

What happens when the milk rate changes mid-month?

Enter the new rate with the date it starts. Days before that date use the old rate and days after use the new one.

Can my milkman tick deliveries on his phone?

Yes, with your own Supabase database. He sees the round in order and ticks each house, and you see it on your phone.

Can customers mark days they don't need milk?

Yes, if the app uses an online database. They mark the dates, and tomorrow's round and their bill change.

Can the app tell me how much milk to collect tomorrow?

Yes. It totals tomorrow's litres by milk type after all changes, so you can plan the collection.

Can the app record fat and SNF from farmers?

You can type in fat and SNF figures if you want, but AppCub doesn't connect to milk testing machines.
