One stock figure for your counter, website and WhatsApp
Billing counters, online stores and loyalty programmes that draw from one inventory, so what the website shows is what the shelf actually holds.
Retail and e-commerce software covers point-of-sale billing, online stores, inventory and customer loyalty. It suits shops, showrooms and online brands in India that sell through more than one channel and need those channels to agree on stock, prices and customers. Our published retail work includes the Pirandai Kadai online store.
The challenges we hear most
- 01
Stock that never matches
Counter sales, online orders and godown transfers are recorded in different places, so items oversell on busy days and dead stock goes unnoticed.
- 02
Marketplace commissions
Commission, shipping and return charges eat into margin, and the marketplace, not you, keeps the customer's details.
- 03
Festival-rush billing queues
Slow billing, missing barcodes and manual GST calculation create queues exactly when footfall peaks at Deepavali and Pongal.
- 04
Customers who buy once
Without a record of who bought what, there is no way to run loyalty points, member pricing or a timely reminder to reorder.
- 05
COD returns and courier chasing
Refused cash-on-delivery parcels cost shipping both ways, and courier status is checked by phone, one order at a time.
What we build
- 01
POS and GST billing
Barcode scanning, GST invoices, multiple counters, a day-end cash tally and billing that continues offline.
- 02
An online store you own
A fast Next.js storefront with Razorpay and UPI, variants, coupons, shipping rules and search-friendly product pages.
- 03
One inventory for every channel
A single stock ledger updated by counter, website and WhatsApp orders, with branch transfers and reorder alerts.
- 04
Loyalty and repeat sales
Points, member prices, birthday offers and WhatsApp messages to past buyers, driven by real purchase history.
- 05
Order and delivery desk
Order status, courier tracking numbers, COD confirmation and returns handled from one screen.
- 06
Owner dashboard
Daily sales by branch, channel and product, with fast and slow movers flagged.
Count the places you sell
Ask a saree showroom owner in Kanchipuram where they sell and the first answer is "the shop". Keep asking and the list grows: the shop, the second branch, the WhatsApp catalogue, Instagram messages, a marketplace or two, and perhaps a new website. Every one of those channels takes orders against the same shelf, and in most businesses each keeps its own record. That is how a single silk saree gets sold twice on a Saturday, and how a slow line sits in the godown for two seasons before anyone notices.
So the real software question in retail is rarely whether you need a website. It is whether every channel can draw from one honest stock figure.
The expensive mistakes retailers make online
- Launching before the product data is ready. A store with two thousand products, half of them missing photos or sizes, sells worse than a well-run WhatsApp chat.
- Ignoring the cost of cash on delivery. A COD parcel refused at the door costs shipping both ways. The store needs rules such as COD limits or order confirmation from the first day.
- Expecting visitors to arrive by themselves. A new store has no traffic until search, social media or existing customers send it. Budget for that, or begin on a marketplace.
- Running the counter and the website on separate systems. This is the root of overselling, and it worsens with every channel you add.
What we build for shops and brands
For the counter, VS Tech Builders builds a POS and billing system with barcode scanning, GST invoices, multiple counters and billing that carries on when the internet drops. For selling online, a store on Next.js with Razorpay and UPI checkout, product variants, coupons and shipping rules. Underneath both sits one inventory ledger that every channel updates, with branch transfers and reorder alerts. Around them, a customer record makes loyalty points, member prices and well-timed WhatsApp offers possible, and an owner's dashboard shows sales by branch, channel and product.
Pirandai Kadai and what a store build really involves
Our clearest retail example is Pirandai Kadai, an online store we built on Next.js and Firebase with Razorpay payments. The work behind any store like that is less about the homepage than about the parts a shopper never notices: a catalogue structured so filters work, a checkout that holds up on patchy mobile data, order notifications that reach the owner instantly, and an admin panel the owner can run without calling us. Kurumban Crafts, an artisan e-commerce store, is launching soon.
Own store, marketplace, or both
Marketplaces give you shoppers and take commission and the customer relationship in return. Your own store keeps the margin and the customer data but has to earn its visitors. Most growing brands need both, and our guide to your own store versus the big marketplaces sets out the trade-offs. If your catalogue is small and you have no repeat buyers yet, a hosted platform is a sensible first step; the Shopify, WooCommerce and custom comparison shows when custom becomes worth it.
Budget and timing
Simple catalogue stores typically start around ₹35,000. A full store with customer accounts, coupons, shipping rules and an admin panel ranges from ₹1,00,000 to ₹4,00,000 and takes 8 to 12 weeks. A billing or inventory system on its own costs ₹50,000 to ₹1,50,000. Plan the launch at least a month before your busiest season, which for most shops means Deepavali, so the 14-day correction window that comes with every project closes well before the rush.

Read the case studyFrequently asked questions
Should we build our own store or keep selling on marketplaces?
For most growing brands the answer is both. Marketplaces bring shoppers who have never heard of you; your own store keeps the margin and the customer's contact details so they can buy again directly. Build your own store when you have repeat buyers, a social following or a catalogue that marketplaces present poorly. Until then, a marketplace listing plus a WhatsApp catalogue is a reasonable, low-cost start.
Can the shop counter and the website share the same stock?
Yes, and that is the main reason to build them together. Every sale, whether from the counter, the website or a WhatsApp order entered by staff, reduces the same stock record, so the website stops offering an item the moment the last piece is billed at the counter. If the shop's internet drops, the POS keeps billing and posts those sales to the ledger once it reconnects.
What does an online store cost for a small brand?
A simple catalogue store with a cart and Razorpay checkout typically starts around ₹35,000. Once you need customer accounts, coupons, shipping rules by pincode, an admin panel and stock linked to your shop, expect ₹1,00,000 to ₹4,00,000 and 8 to 12 weeks. The biggest variables are catalogue size, how messy the existing product data is, and whether the store must connect to a billing system you already use.
Does a retail shop need its own mobile app?
Usually not at first. A fast mobile website and WhatsApp handle most shoppers, and few customers will install an app to buy from a shop once a month. An app earns its cost when customers order often, as with groceries, daily essentials or pharmacy refills, and when loyalty points and push notifications bring them back. Android apps typically start around ₹65,000 once that point arrives.
