Water can software that counts the cans, not just the litres
Daily delivery sheets by route, a ledger of every can and deposit, monthly subscription billing and an app your delivery staff can use without signal.
Water can supplier software plans each day's deliveries by route, tracks every can and deposit, bills monthly subscriptions and gives delivery staff an app that works without signal. It is built for suppliers whose real stock is the can, and whose profit leaks through unreturned cans and uncollected cash.
Where the day goes wrong
- 01
Cans that never return
Each can is an asset, yet customers keep spares or lose them while the count lives in a delivery boy's head.
- 02
Deliveries missed in billing
Extra cans delivered on a hot day are never written down, so they are never billed.
- 03
Cash that stays in pockets
Delivery staff collect cash on the route and hand over what they remember at the end of the day.
- 04
Subscription changes by phone
Pauses, extra cans and address changes reach the route only if someone relays them in time.
- 05
Month-end billing chase
Invoices are written by hand and chased by phone, apartment by apartment.
What we build for you
- 01
Customer and route master

Delivery staff app
An Android app that shows the stops, records cans out and empties in, and takes payment, even without signal.
- 04
Can and deposit ledger
Cans held by each customer, deposits taken and refunded, and a list of customers holding more than agreed.

Subscription billing
Monthly invoices with a UPI payment link, reminders and a clear record of what is paid.

End-of-day reconciliation
Cans loaded against delivered and returned, and cash collected against cash handed in.
The asset is the can, not the litre
A water can supplier sells water, but the business runs on cans. A 20-litre can that leaves the plant is a piece of equipment that must come back. Every customer who keeps a spare, every apartment that stacks empties in a corner and every can that quietly becomes someone's flower pot is money gone.
Most suppliers know their litres and guess their cans. A deposit is taken at the start, the number of cans each customer holds is remembered by the delivery boy, and the ledger is a notebook that is a week behind.
One morning on one route
Picture a route in a Madurai neighbourhood: forty-odd stops across three apartment blocks, a few shops and a clinic. The delivery boy needs a list, in order, showing who takes how many cans, who is away this week, how many empties to collect and who still owes last month. Today that list is a page from a notebook, rewritten each evening by whoever has time.
With software, the sheet is generated each evening from subscriptions and pauses. In the morning the app on his phone shows the stops in order. He taps delivered, enters cans out and empties in, records cash or UPI, and marks the stop as away when the door stays shut. If the signal drops in a basement car park, entries wait on the phone and sync later.
Leaks you only see at month end
- Cans that do not return. A customer holding four cans against a deposit for two is invisible without a ledger.
- Deliveries never billed. Extra cans on a hot day go unrecorded, so they go unbilled.
- Cash in transit. Collections reach the office as whatever the delivery staff remember.
- Changes by phone call. A customer pauses for a week and the route finds out after a wasted trip.
- Billing by hand. Invoices for each apartment are prepared at month end and chased one call at a time.
Two halves of one system
The delivery staff app is the half the route sees. The office half holds the can ledger, deposits, pauses and monthly billing, and shows the owner each route's cans, cash and complaints at a glance.
The link between them is the evening reconciliation: cans loaded against cans delivered and returned, and cash collected against cash handed in. A difference appears the same night with a name beside it, instead of at month end with nobody's.
Customers get a simple link on WhatsApp with their invoice and a UPI payment button. A payment made through it marks the invoice paid without anyone retyping a figure.
Begin with one route
Pick your messiest route and run it for a month alongside the notebook. The first report you will want is the can ledger: how many cans does each customer really hold? Most owners find a surprise there. Add the remaining routes once the first one balances.
Price, timeline and ownership
A delivery staff Android app typically starts around ₹65,000 and can be ready in 6 to 8 weeks. A full route, can and billing system with the office side typically starts around ₹85,000 and takes 8 to 12 weeks. VS Tech Builders can publish the app through your own Google Play developer account, which our Play Store publishing service covers, and the accounts and source code move to you on the final payment.
When a notebook still wins
A single van serving a few dozen regular customers can run on a notebook and a UPI QR code. Software begins to pay when you have several routes, more than one delivery person and cans you cannot count. Our guide to staff apps for field teams explains what changes when delivery staff carry the system in a pocket, and offline-first app development shows how the app copes with lift lobbies and basements where signal vanishes.
Frequently asked questions
How does the system know how many cans each customer holds?
Every delivery records cans given and empties taken, so the ledger keeps a running balance per customer beside the deposit paid. At any time you can list customers holding more than they agreed to, or customers who have not returned empties for weeks. What you do about it, whether a reminder, a charge or a conversation, stays your decision.
Can customers pause deliveries when they travel?
Yes. The office, or the customer through a WhatsApp reply that the office logs, sets the paused dates. Paused days drop off the next delivery sheet and off the monthly invoice, so the route makes no wasted trip and the customer is not billed. Resuming is automatic on the end date unless you change it.
Do delivery staff need an expensive phone or mobile data all day?
No. An ordinary Android phone is enough, and we test on low-priced models. The app saves each delivery on the phone and syncs when a connection is available, so basements, lift lobbies and patchy areas do not stop the work. Some suppliers keep phones that stay with the route, which avoids personal numbers and data plans.
Can monthly bills be paid by UPI and marked as paid automatically?
Yes. Each invoice carries a payment link, built on a gateway such as Razorpay, and a successful payment marks the invoice as paid without retyping. Cash collected on the route is entered in the app and reconciled in the evening. Customers who prefer to pay to your own UPI QR can still do so, and your office matches those payments.
