How to make an app for a water can supplier

A water can business loses money in two quiet ways: cans that never come back, and cans delivered but never billed. An app records every can delivered and every empty collected for each customer, keeps the deposit, makes the month's bill and gives each delivery boy his round by building.

Updated 2026-11-09

Who uses the app

The owner and the delivery boys, and optionally regular customers who order a can with one tap. Delivery boys and customers use their own phones, so connect your own Supabase database with sign-in.

The screens a water can supplier app needs

Orders: New can orders from customers and calls, by area and time, with the delivery boy assigned
My round: For the delivery boy: addresses by building and floor, cans to drop, empties to pick, and a call button
Customers: Flat or office, phone, rate, deposit paid, cans with them now and the month's count
Order a can: For customers: the number of cans and a 'send' button; the order reaches the owner's list
Monthly bills: Cans delivered per customer this month, the rate, the total and a PDF bill for WhatsApp
Cans out: All cans with customers, and customers holding more empties than usual

Features worth asking for

Full and empty cans counted at every delivery, so you always know how many cans each customer holds
Deposits recorded and refunded when cans come back
A monthly bill as a PDF, with a WhatsApp button and the amount filled in
A UPI QR or 'Pay via UPI' button on the bill, paid straight to you
Payments through your own Razorpay inside the customer app, if you connect it
Rounds sorted by building and floor for each delivery boy
A daily count of cans filled, delivered and returned for the plant

Where the data lives

With delivery boys and customers on their own phones, connect your own Supabase database from the chat and turn on sign-in. If customers should pay inside the app, connect your Razorpay account too; the money goes to you.

Tips for a water can supplier app

Count the cans with every customer once before you start, and enter that as the opening number.
Make the delivery boy tick full and empty cans at the door; that one habit stops can losses.
Give offices their own rate and monthly bill; they usually pay by bank or UPI at month end.
Share the customer app as a web link in society WhatsApp groups; nobody has to install anything to order a can.
Start with your own team for two weeks before inviting customers.

Good to know

The app has no live tracking of delivery boys and doesn't send order alerts from a customer's phone to yours by itself; orders appear in the list when the app is open. It doesn't connect to the plant's machines or meters.
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 track how many cans each customer has?

Yes. The delivery boy records full cans dropped and empties picked at every delivery, so each customer's can count stays right.

Can customers order a water can with one tap?

Yes, with your own Supabase database. The customer taps 'order', and the order appears in your list with their address.

Will I get an alert when a customer orders?

Not from the customer's phone to yours by itself; that needs a push service you set up. Orders show in your list when you open the app, so check it often or keep it open.

Can the app make monthly water bills?

Yes. It counts cans delivered to each customer in the month, uses their rate, and makes a PDF bill to share on WhatsApp.

Can I keep can deposits in the app?

Yes. Record the deposit when a customer starts and mark it refunded when the cans are returned.

Can customers pay online?

Yes. Show your UPI QR on the bill, or connect your own Razorpay for a payment button in the app; the money goes to you.
