- Who it's for
We work with online-first sellers, both brands and resellers, who run their own web store alongside Amazon, Flipkart and other marketplaces. Our focus is the operational software behind the storefront as much as the storefront itself.

How to start
Tell us what you need in your own words. You talk to the developers who would build it and get a written, line-item estimate.
Get a project estimateWhat running an online store involves day to day
Once an online store takes more than a handful of orders a day, the hard problems move behind the storefront. Stock has to stay in sync across your site and every marketplace. Orders need allocating to a warehouse, a courier and a label. Cash-on-delivery parcels come back unopened, and each return has to be inspected, restocked or written off.
We build e-commerce software that treats these operations as first-class features: an order pipeline you can see and control, courier and payment integrations that fail gracefully, and a catalogue your team can edit without a developer. The storefront sits on top, fast on mid-range Android phones and patchy mobile networks.
Challenges
Operational problems online sellers bring to us
Overselling across channels
Your site, Amazon and Flipkart each hold their own stock count, and manual updates lag behind real sales.
Returns and RTO losses
Unconfirmed COD orders, failed delivery attempts and return-to-origin shipments quietly eat into margin.
Courier juggling
Different pincodes suit different couriers, and tracking updates arrive in formats your support team can't search.
Slow mobile storefronts
Heavy themes and plugins make product pages sluggish on the budget phones most shoppers use.
Solutions
Solutions suited to e-commerce operators

E-commerce capabilities we engineer

OTP or WhatsApp confirmation for COD orders, pincode-level COD rules and partial prepaid options.
Returns and exchanges portal
Customer-initiated returns with photos, reverse pickups, quality checks and refund or store-credit rules.
GST invoicing
Invoices with correct HSN codes and tax splits, credit notes for returns and exports for your accountant.
How it works
How an online order becomes a delivered parcel
Each step is automated where it can be and visible to your team where it cannot.
- Storefront
Step 1: Shopper checks out
They pay by UPI, card or wallet, or choose cash on delivery. A prepaid order is confirmed only after the payment gateway verifies the payment on the server.
- Automated message
Step 2: COD order is confirmed
Cash-on-delivery orders get an OTP or WhatsApp confirmation, and pincodes with poor delivery history can be nudged towards prepaid before anything ships.
- Order system
Step 3: Stock syncs across channels
The sale reduces stock on your site and pushes the new count to each marketplace, so the same unit is not sold twice.
- Warehouse staff
Step 4: Warehouse picks, packs and labels
A pick list, a packing check and a courier label with its AWB number come from one screen.
- Courier partner
Step 5: Courier delivers
Tracking webhooks update the order automatically, and a failed attempt raises a reattempt task instead of quietly turning into an RTO.
- Returns desk
Step 6: Returns are resolved
Returned items are inspected, then restocked or written off, and the refund or store credit goes out with a GST credit note.

Plain-English glossary
E-commerce terms, in plain English
- RTO (return to origin)
- A parcel the courier brings back because delivery failed or a COD buyer refused it. You pay shipping both ways and the stock is stuck in transit, so cutting avoidable RTO protects margin directly.
- AWB number
- The air waybill number a courier assigns to each shipment. It is printed on the label and used for tracking, so your system stores it against the order and updates the status on its own.
- Webhook
- An automatic message one system sends another when something happens, such as a courier marking a parcel delivered or a gateway capturing a payment. It lets orders update themselves without anyone refreshing a portal.
- Headless build
- The storefront shoppers see is built separately from the commerce engine behind it. It costs more to start than a themed store, but gives you full control over speed, design and checkout.
- HSN code
- The classification code on a GST invoice that decides the tax rate for each product. Setting it correctly per product avoids wrong tax on invoices and awkward corrections at filing time.
Product preview
Checkout, warehouse and returns screens
Sample screens from a typical build; the order pipeline behind them matters as much as the storefront.
Shopper app. Checkout offers UPI, cards, net banking and COD, and confirms a prepaid order only after the gateway verifies payment, so nothing ships unpaid by mistake. 
Operations panel. Your team sees orders from the website and every marketplace in one queue, with COD confirmation, picking and courier label status side by side. 
Returns desk. Returned parcels are checked against the customer's photos and reason, then restocked or written off, with the refund or store credit issued from the same screen. 
Channel dashboard. Owners see orders, stock mismatches and return-to-origin rates by channel, so problems surface in one place instead of as cancelled orders.

Cost drivers
Cost drivers for e-commerce builds
Platform approach
Extending Shopify or WooCommerce costs less upfront than a custom or headless build, but limits how far checkout and operations can change.
Channels to sync
Each marketplace, POS or warehouse system you connect adds mapping, error handling and monitoring.
Catalogue complexity
Variants, bundles, B2B pricing and large SKU counts affect data modelling, search and import tooling.
Operations tooling
Returns workflows, warehouse picking screens and custom reports are often as much work as the storefront.
Estimates are written from your scope, with the effort and assumptions behind each line item.

FAQ
Frequently asked questions
Should we use Shopify or build a custom e-commerce platform?
It depends on how different your operations are. Shopify or WooCommerce is usually the sensible start when catalogue, checkout and fulfilment are standard, and we can build custom apps or integrations on top. A custom or headless build makes sense when you need unusual pricing, B2B flows, deep marketplace or ERP integration, or full control over performance and data. We'll set out both options, including running costs, before you commit.
How do you reduce COD returns and RTO?
Software can't eliminate RTO, but it can cut avoidable cases. Common measures are confirming COD orders by OTP or WhatsApp before dispatch, limiting COD for pincodes and customers with poor delivery history, nudging buyers towards prepaid with small incentives, and acting quickly on courier non-delivery reports so a reattempt is scheduled. We build these as configurable rules your team can tune as data comes in.
Can you connect our store to Amazon and Flipkart?
Yes, through Amazon's Selling Partner API and Flipkart's seller APIs, subject to the access your seller accounts have, or through a multichannel tool if you already use one. The usual scope is product and stock sync, order import and status updates. We add a reconciliation view so mismatches show up in one place instead of surfacing later as cancelled orders or customer complaints.
Which payment gateways do you integrate?
Most Indian stores use Razorpay, Cashfree, PayU or PhonePe's payment gateway for UPI, cards, net banking, wallets and EMI. We implement webhooks and server-side verification so an order is confirmed only once payment is actually captured, plus refund APIs for returns and cancellations. For international buyers, Stripe or PayPal can run alongside your domestic gateway, with currency and tax handling planned upfront.
