How to calculate a monthly milk bill

By Milk walla · 3 November 2026

Start with the milk actually delivered

A monthly milk bill should use the delivery entries for that customer, rather than assuming every calendar day had the same delivery. Record the date, morning or evening round, quantity in litres, and agreed price per litre. A skipped day contributes no delivery charge. For a different quantity or rate, use the values that applied to that entry. Convert millilitres to litres before calculating: 500 ml is 0.5 L, 600 ml is 0.6 L, and 1.25 L is already in litres.

Worked example: variable daily quantities

Suppose a customer receives 1 L on 20 days and 0.5 L on 10 days, all at ₹60 per litre. The total is (20 × 1) + (10 × 0.5) = 25 L. The delivery charge is 25 × ₹60 = ₹1,500. If there is an opening amount due of ₹200 and the customer pays ₹1,000, the remaining amount is ₹200 + ₹1,500 − ₹1,000 = ₹700. These are example figures, not an app price or a customer’s actual bill. If the rate changed during the month, total each delivery’s charge instead of applying one rate to all litres.

Check and share the statement

Before sharing a bill, compare the quantity total with the delivery history, verify any opening balance, and check the dates and amounts of payments. A balance carried forward must not be added twice. Keep received payments separate from delivery charges so a customer can understand both. In Milk walla, review customer records and monthly bills, then use the available sharing options. Check the recipient before sending a statement on WhatsApp. A prepared message is not sent until you choose to send it.
