What we build for grocery stores and dairies

The customer side, the store side and the delivery side, all using the same stock and the same orders.

Website

A fast store website that works on cheap phones and slow data, so walk-in customers can also order from home.

  • Category pages for staples, fresh produce, dairy and household
  • Pincode and society check before checkout
  • Weekly offers page your staff can update
  • Google Business Profile and local search setup
  • Bulk and party order enquiry form

Mobile App

An Android and iPhone app for repeat buyers, plus a separate delivery boy app for your riders.

  • Reorder last month list in one tap
  • Morning and evening delivery slots
  • Milk and bread subscriptions with pause
  • Rider app with route order and cash collected
  • Order alerts on WhatsApp and push

Store Admin & Inventory

The back office where orders get packed, weighed, billed and dispatched.

  • Picking list sorted by shelf and aisle
  • Weight-based final billing for loose items
  • Stock sync with your billing software
  • Customer credit (khata) and wallet ledger
  • Daily cash, UPI and COD reconciliation

What a grocery business needs online in India now

A grocery customer in India does not shop like an ecommerce customer. They buy the same 30 to 40 items every month, they want milk before 7 in the morning, they expect the store to call if coriander is not fresh today, and many still want to pay cash or settle a monthly khata. Quick commerce has taught them to expect speed, but they still trust the neighbourhood store for quality and credit.

So a grocery app is not a catalogue with a cart. It is an ordering system built around repeat lists, delivery slots, loose items that are weighed after the order is placed, substitutions when something is out of stock, and a delivery team that collects cash and UPI at the door. For dairies, it is a subscription engine: a fixed quantity every morning, paused when the family travels, with a monthly bill or a prepaid balance.

This page is for kirana owners who want to keep their regular customers from drifting to quick commerce, supermarket chains with two or more outlets, dairies and milk distributors running daily routes, and fruit, vegetable or organic stores that sell to fixed housing societies. Infoways builds the customer app, the store website, the delivery boy app and the admin panel together from our office in Mahape, Navi Mumbai, and we work with stores across Mumbai, Thane, Pune and the rest of India.

Food businesses selling online should show their FSSAI licence number; we put it in the app footer and on every receipt.

Problems We Fix

Where grocery stores lose money, and how software stops it

Loose items billed wrong

A customer orders 1 kg of onions and the packer puts in 1.15 kg. The app lets the packer enter the actual weight, recalculates the bill, and charges or refunds the difference before dispatch.

Phone and WhatsApp orders get lost

Orders typed on WhatsApp at 10 pm are missed or misread. With an app, every order comes in as a clean list with quantities, address and slot, and a WhatsApp order can be keyed into the same system by staff.

Milk not delivered, nobody knows why

Daily routes run on a paper register. The rider app marks each drop as delivered, skipped or customer not home, so you can answer a complaint with a time and a photo instead of an argument.

Khata balances nobody can trust

Credit written in a notebook leads to disputes at month end. A digital ledger shows each order, payment and adjustment to the customer in the app, and sends a WhatsApp reminder when the bill is due.

Out of stock after the order is placed

Stock sync with your billing software hides items that are finished. When something runs out during packing, the customer picks a substitute or a refund in the app instead of getting a surprise.

Regulars drifting to quick commerce

You cannot beat a dark store on ten-minute delivery, but you can win on a one-tap monthly list, fresher produce, credit for known families and a reward on every repeat order.

Example: a two-outlet supermarket and dairy route in Kharghar

Say you run two supermarkets in Kharghar and a milk route of a few hundred homes across nearby housing societies. Orders come by phone and WhatsApp and milk is tracked in a register. The numbers below are only illustrative.

A family sets up a milk plan in your app: 1 litre of toned milk daily and bread on Sundays. The order engine creates their drop for the 6 to 7:30 am route each evening at a cut-off you choose, say 9 pm. When they leave for a week, they tap pause; the next morning their drop simply does not appear on the rider list. At month end the app shows 26 deliveries, 4 paused days, and the total. They pay by UPI from the app, or the amount is taken from a prepaid balance they topped up earlier.

The same family places a monthly order on Saturday: a saved list of 32 items, with 2 kg tomatoes and 1 kg onions as loose items. The order reaches the nearer outlet by pincode. The picking screen sorts items by aisle. The packer weighs the tomatoes at 2.08 kg, enters it, and the final bill updates by a few rupees. Coriander is finished, so the app asks the customer to accept methi or skip it. The order is packed, an invoice is printed, and it is assigned to a rider for the 5 to 7 pm slot.

The rider app shows six stops in route order. This customer pays Rs 2,340 in cash, the rider marks it collected, and the admin panel tracks each rider's cash in hand. Your manager closes the day with one report covering orders, payments, cash per rider and milk drops.

How We Build It

How Infoways builds a grocery ordering system

  1. 01

    Store walk-through and order audit

    We watch your counter and packing area, read a week of WhatsApp and phone orders, and note how you handle loose items, credit and milk routes.

  2. 02

    Catalogue and stock plan

    We agree product names, which items sell by weight, pack or piece, and how stock comes from your billing software. Clean product data is the slowest part, so it starts first.

  3. 03

    Design for real customers

    Large buttons, Hindi or Marathi labels if you want them, and a home screen that puts last order and milk plan first.

  4. 04

    Build the apps and admin panel

    Customer app, store website, rider app and admin are built together on one backend, usually in Flutter so Android and iPhone share one codebase.

  5. 05

    Trial with one outlet or one route

    We run a pilot with one store or one milk route for two to three weeks, fix what the packers and riders struggle with, then roll out to the rest.

  6. 06

    Launch and local marketing

    Play Store and App Store publishing, then society-level promotion: QR standees at the counter, WhatsApp broadcasts to existing customers and local SEO so the store shows up for "grocery delivery near me".

Integrations

Integrations a grocery app usually needs

  • UPI intent and collect, cards and wallets through Razorpay, PhonePe PG or Cashfree
  • UPI Autopay mandates for monthly milk bills, through a gateway that supports it
  • Closed-loop prepaid wallet usable only inside your own app, for milk advances and refunds
  • Billing and stock sync with your POS or accounting software, such as Tally or Marg, through export or API
  • Barcode scanning in the packing screen to cut picking errors
  • WhatsApp Business API for order confirmations, slot changes and khata reminders
  • Google Maps for address pins, society and wing mapping, and rider route order
  • Thermal printer support for invoices and packing labels
  • SMS OTP login, since many older customers do not use email
  • Optional ONDC seller-side connection if you want to be listed on ONDC buyer apps

Cost and timeline for a grocery app

A small store that only needs a clean online catalogue with UPI and cash on delivery can start lower, with a Shopify or WooCommerce build and a simple app wrapper. A custom grocery store with apps, weight-based billing, slots, khata and an admin panel typically falls in the Rs 6-15 lakh range. Add your own rider app with live tracking, multiple outlets routing by pincode, and a full milk subscription engine, and it usually moves into the Rs 10-25 lakh range. All prices are typical ranges, GST extra, and depend on scope.

Three things push the cost up most: messy product data, two-way sync with an old billing system that has no API, and complex subscription rules. A first version usually takes 10 to 16 weeks. Yearly upkeep is usually 15-25% of the build cost. Our guide to app development cost in India explains how these numbers are worked out.

Grocery app mistakes to avoid, and when not to build yet

The most common mistake is launching with 8,000 products copied from a distributor list, half of them without photos or correct prices. Customers find three versions of the same milk, one at the wrong price, and stop trusting the app. Start with the 600 to 1,500 items that make up most of your sales and add the rest slowly.

The second mistake is promising ten-minute delivery. A neighbourhood store cannot run a dark store, and chasing speed burns money on riders. Compete on slots you always meet, fresh produce and credit.

And sometimes an app is too early. If you get fewer than 15 to 20 home delivery orders a day, a WhatsApp catalogue plus a good Google Business Profile will serve you better for now. Build the app when phone orders or the milk register become hard to manage.

Ready to move phone orders and milk routes onto one system?

Share a week of your orders and your delivery area. We will suggest the smallest version that pays for itself first.

Grocery app development: common questions

Can the app handle items sold by weight, like vegetables and dry fruits?

Yes. Loose items are ordered by approximate weight. The packer enters the actual weight at packing, the bill is recalculated, and the customer pays the final amount on delivery or the difference is charged or refunded online.

How do milk subscriptions work in the app?

The customer sets a daily or alternate-day quantity, the system builds the next morning's route list at a cut-off time you choose, and they can pause, add extra or change quantity before the cut-off. Billing can be monthly, from a prepaid balance, or by UPI Autopay where your gateway supports it.

Can I keep giving credit (khata) to regular customers?

Yes. You set a credit limit per customer. Orders are added to their ledger, payments are recorded against it, and the app shows them their balance and sends a reminder on the due date. You decide who gets credit.

Will it work with my current billing software?

Usually, yes. If your billing software has an API we connect to it directly. If it only exports files, we set up a scheduled stock and price import. We check this in the first meeting because it affects the cost.

Do I need a separate app for delivery boys?

For more than two or three riders, yes. The rider app shows assigned orders in route order, marks deliveries, records cash and UPI collected, and lets the manager see who is where. For a single rider, a simple delivery screen inside the admin panel is enough.

Do I need an RBI licence for a wallet in my grocery app?

A closed-loop wallet, where the balance can only be used to buy from you inside your own app and cannot be withdrawn or sent to others, does not need an RBI prepaid payment instrument licence. If you want customers to withdraw or transfer the balance, that is a different product and needs a licensed partner.

How long does a grocery app take?

Usually 10 to 16 weeks, including a pilot with one outlet or route. Ready product data keeps it short.

Should I join ONDC or build my own app?

They are not either-or. ONDC can help new customers find you through buyer apps on the network. Your own app is where regular customers reorder, use credit and manage subscriptions. We can plan both, and start with whichever brings more orders for your area.

Give your regular customers a reason to order from you, not an aggregator

From milk routes to monthly lists, we build the grocery app, website and admin panel as one system. Call or WhatsApp +91 79770 75981.
