Short answer: Water can delivery management software tracks every 20-litre can in your inventory from plant to customer and back, manages refundable deposits, generates daily route sheets for drivers, handles standing orders and ad-hoc requests, and produces recurring invoices — replacing the notebooks and WhatsApp group chaos that break down past 200 active customers.
Why a notebook stops working past 200 customers
A water can delivery business with 200 customers has a deceptively complex inventory problem. The physical cans — typically 20-litre food-grade polycarbonate or PET — are worth ₹200–350 each and are on loan to customers as part of a refundable deposit arrangement. If you do not track where each can is, you lose cans. Losing 50 cans per month at ₹250 each is ₹12,500 in monthly capital erosion — more than the margin on hundreds of deliveries.
Add recurring billing, route optimisation, and the operational gap between standing orders and ad-hoc requests, and the complexity of a notebook becomes clear.
Can inventory: the foundation of the system
Every can must have a record. The most practical approach for small-to-medium operations is lot-level tracking rather than individual can barcodes — barcoding every can adds significant scanning overhead at the plant. Lot tracking means:
- Total cans in inventory at the plant (filled and empty)
- Cans dispatched on each route (delivery)
- Cans returned on each route (empties collected)
- Cans outstanding at each customer location
- Cans written off as lost or damaged
| Can location status | What it represents |
|---|---|
| At plant (filled) | Ready for delivery |
| At plant (empty) | Awaiting refill |
| At customer | Deposited; to be collected on next delivery |
| In transit | On the delivery vehicle |
| Written off | Lost, stolen, or damaged beyond use |
The daily route sheet closes the loop: driver leaves with X filled cans and returns with Y empties. The difference is what should be at customer locations. If the running customer balance does not match the physical count during a quarterly audit, the system identifies which customers have outstanding cans.
Deposit tracking
A refundable deposit of ₹150–400 per can is standard across most Indian water delivery businesses. The deposit module must:
- Record deposit paid per can at customer onboarding
- Track how many cans are currently at the customer's location (each can = one deposit unit outstanding)
- Calculate the refund due when a customer terminates service
- Handle the common case where a customer takes an extra can without formally requesting it — the deposit is collected on the next bill or in cash at delivery
Deposit accounting is often the weakest part of off-the-shelf solutions. A customer who has had service for 3 years may have been on different can counts at different times. The system needs a running ledger — not just a single "deposit paid" figure.
Standing orders and ad-hoc deliveries
Most water can customers are on a standing order: X cans every Y days. Common patterns are:
- Residential: 1–2 cans every 3–4 days
- Small office: 2–4 cans every 2 days
- Restaurant: 4–8 cans daily
- Apartment complex (bulk): 20–60 cans daily via a separate bulk delivery contract
The software auto-generates the next delivery from the standing order schedule. Ad-hoc requests (an extra can today, a pause for two weeks while the customer travels) are overlaid on the standing order. Pause and resume must be handled without losing billing continuity — a paused account should not generate invoices for the pause period and should resume automatically on the confirmed date.
Route sheets and driver workflow
A route sheet for a driver covers 30–80 stops per day in a defined zone. The system generates the route in delivery-sequence order (not alphabetical by name). Each stop shows:
- Customer name and address
- Cans to deliver (from standing order or today's order)
- Empties to collect from last delivery
- Any payment collection due
- Special instructions (gate code, building access, preferred delivery time)
| Route metric | Typical value for urban Indian operations |
|---|---|
| Stops per route per day | 30–80 |
| Average delivery time per stop | 3–6 minutes |
| Routes per operation (small-medium) | 2–8 |
| Vehicle type | Auto-rickshaw, tempo, or mini-truck |
| Peak delivery window | 6–10 AM |
A driver app (Android, offline-capable) allows the driver to mark each stop as delivered, note empties collected, and flag issues (customer absent, address unclear). OTP-based delivery confirmation is an option for premium customers. The end-of-route reconciliation — cans out, cans in, cash collected — is submitted from the app and auto-reconciled against the day's route sheet.
Recurring billing and payment collection
Water can billing is high-frequency and low-value per transaction — ₹20–45 per can delivered, billed weekly or monthly. The billing module must:
- Calculate the bill from the delivery record (not from the standing order) — a customer who received 18 cans in a month despite a 20-can standing order is billed for 18
- Handle multiple bill formats: prepaid wallet, postpaid monthly, or cash-on-delivery
- Apply GST correctly — packaged drinking water attracts 12% GST, but the treatment for small delivery businesses varies by registration status
- Generate and send WhatsApp or SMS invoices automatically on billing day
- Flag overdue accounts for collection follow-up
See GST billing software guide for how GST applies to water delivery businesses at different turnover thresholds.
For larger operations considering automation across billing, inventory, and route management, business process automation for Indian SMBs is useful context.
What does water can delivery software cost?
A custom system for a single-location operation (1–8 routes, up to 1,000 active customers) covering can inventory, standing orders, route sheets, a driver app, and monthly billing costs ₹2L–4L. Adding GPS route tracking, customer-facing app for self-service orders, and integration with a payment gateway (Razorpay/PayU) for prepaid wallet top-up puts the range at ₹5L–8L.
SaaS products in this niche exist at ₹3,000–8,000/month but often lack the deposit ledger sophistication and offline driver app that Indian operations require. NexaEx builds at fixed price with full code ownership — see our pricing and software cost benchmarks for India.
Key questions before choosing a system
- Can the driver app work offline in areas with patchy mobile data?
- Does the system track individual can deposits or just a lump deposit figure per customer?
- Can standing orders be paused and resumed without breaking the billing history?
- Is customer data and delivery history exportable at any time?

Frequently asked questions
How does the system know how many cans are at each customer location?
The system maintains a running can balance per customer. Each delivery adds to the balance; each empty collected subtracts from it. When a customer is first onboarded, their starting balance is zero. After the first delivery of 2 cans, their balance is 2. When the driver collects 2 empties on the next visit, the balance returns to zero. A quarterly audit report flags customers whose system balance differs from the physical count reported by the driver, making it easy to identify where cans are being lost.
What happens if a customer wants to pause delivery for two weeks?
The standing order is marked as paused with a resume date. The system does not generate deliveries or invoices during the pause window. On the resume date, deliveries restart automatically based on the original standing order. The billing history shows a clean gap with no charges for the pause period. If the customer also wants empties collected before the pause, that can be scheduled as a one-time collection stop on the last day before the pause begins.
How does deposit refund work when a customer closes their account?
The system calculates the refund as: deposit per can multiplied by the number of cans currently at the customer location (the can balance). Before issuing the refund, the driver collects all outstanding cans on the final delivery stop. Once the driver confirms all cans returned and the balance is zero, the accounts team processes the refund. If any cans are missing, the deposit for those cans is withheld. The customer receives a closing statement showing cans returned, deposit released, and any outstanding balance deducted.
Can the software handle both individual residential customers and bulk apartment complex contracts?
Yes — the customer type affects billing and route logic. Individual customers are billed per delivery based on their standing order. Apartment complex contracts typically have a bulk daily order, a single invoice to the building manager or RWA, and a separate delivery protocol (goods lift access, stacking in the water room). The route sheet for bulk stops shows the total cans and any special access instructions. Billing for bulk contracts can be on a different cycle — weekly or biweekly — from residential billing.
