Standing orders, per-customer rates, pauses and mid-month rate revisions all handled — then a month of deliveries becomes itemised GST invoices, sent on WhatsApp, with dues tracked to the rupee.
It is a daily product with a monthly invoice, and almost every customer's month is slightly different from every other customer's month.
One litre most days, two when guests come, none for the ten days the family was away. A monthly bill is the sum of thirty different days, not a fixed amount.
Cow and buffalo differ, long-standing customers have old rates, and bulk households were promised something else. Held in one person's head, this does not survive a busy month.
When the rate changes on the 12th, every bill needs splitting across two rates. Done by hand, this is where most billing errors come from.
Some customers pay in advance, some settle partly, some carry an old balance. Without a ledger per customer, nobody is certain who owes what.
Copying a month of deliveries into bills takes evenings. During those evenings, collection has not started — so cash arrives later every month.
Reminder calls to neighbours and long-standing customers are uncomfortable, so they get delayed — and receivables quietly grow.
The bill is not typed. It is assembled from what was actually delivered.
Each customer's standing order lives in one place — product, quantity, shift and schedule.
Rates are stored against the customer, not remembered. Special rates stay correct even in a rush.
At month end the entire customer base is billed from the delivery record, not from a notebook.
Invoices reach the customer where they already are, with an itemised day-by-day breakdown.
Every payment, advance and outstanding balance sits on one running ledger per customer.
When a bill is questioned, the answer is a dated delivery list rather than a difficult conversation.
Nothing in this sequence requires you to remember anything.
A customer is set up once: two litres of cow milk, every morning. That standing order drives the delivery list from the next day onwards.
Riders mark what was actually delivered — including the day a customer asked for an extra litre, and the week they were away. The bill will follow the record, not the assumption.
Each delivered quantity is priced from that customer's own rate card. If the rate changed on the 12th, days before and after are priced separately without anyone splitting the month by hand.
At month end, every customer's invoice is produced together — itemised by day, totalled, with GST applied where it is due. What took several evenings becomes a single action.
Bills go out on WhatsApp on the same day. If a bill stays unpaid, reminders go on their own, so collection starts early in the month and does not depend on anyone making an uncomfortable call.
Cash taken at the door, a UPI transfer or a bank payment is recorded against the customer's ledger. Advances adjust automatically against the next bill, and the outstanding figure is always current.
The delivery records that feed these invoices come from the milk delivery management side of LactoSync, and owners review it all from the dairy owner app. Customers see their own bills in the customer app.
