Get a project estimateBuilt for how Indian shoppers browse and pay
Indian shoppers switch between UPI apps, expect a clear COD option, check delivery dates by pincode and often buy on a mid-range Android phone over an unsteady connection. A store that ignores any of these loses orders quietly.
We map your order flow first, from catalogue and pricing to payment, shipping, returns and refunds, then choose the platform. A new D2C label may need a well-configured Shopify store with a few custom apps; a distributor with tiered pricing and credit limits usually needs a custom B2B portal linked to its accounting system.

How it works
How an online order moves from tap to doorstep
What happens between a shopper’s first search and the seller’s payout, and which part of the system handles each step.
- Storefront or shopping app
Step 1: Shopper finds the product
Fast collection pages, filters and search help shoppers on mid-range phones find the right size, colour or variant quickly.
- Checkout
Step 2: Checks delivery and pays
A pincode check shows the delivery date before payment; the shopper pays by UPI, card or EMI, or chooses cash on delivery within limits you set.
- Order system
Step 3: The order is confirmed
Prepaid orders are confirmed by the payment gateway’s webhook; COD orders get a WhatsApp or IVR confirmation first, cutting fake and impulse orders.
- Seller or warehouse
Step 4: Seller packs with invoice and label
The order appears on the seller dashboard with a GST invoice and courier label ready to print, and the pickup is booked automatically.
- Courier
Step 5: Courier delivers while the shopper tracks
Tracking updates flow from the courier’s API to the shopper’s phone; a failed delivery attempt raises an alert so your team can arrange a reattempt.
- Admin panel
Step 6: Returns, refunds and seller payouts
Approved returns trigger a reverse pickup and refund, and marketplace sellers are paid their share after commission on a fixed schedule.

Plain-English glossary
E-commerce terms, in plain English
- SKU
- A stock-keeping unit: one sellable variant, such as a kurta in size M in indigo. Tracking stock per SKU stops you selling items you do not have.
- RTO (return to origin)
- When a parcel cannot be delivered and travels back to you, most often on cash-on-delivery orders. You usually pay shipping both ways, so cutting RTO directly protects your margins.
- NDR (non-delivery report)
- The courier’s notice that a delivery attempt failed. Acting on it quickly, by calling or messaging the shopper, turns many would-be returns into delivered orders.
- Headless commerce
- Running the shop’s engine (catalogue, cart, orders and payments) separately from the storefront customers see. The design can be fully custom and fast while the order system stays proven.
- GST TCS for marketplaces
- Tax collected at source that a marketplace operator deducts from sellers’ payouts and reports to the government. A marketplace needs it calculated per seller and filed every month.
- Pincode serviceability
- Checking, before payment, whether a courier delivers to the shopper’s pincode and how soon. It prevents orders you cannot fulfil and sets honest delivery dates.
Product preview
What shoppers, sellers and your team will see
Illustrative screens from a fashion store with several sellers: the shopping app, a seller dashboard and the admin panel.
Shopping app. Collection pages show sizes, prices and stock at a glance and load quickly on mid-range phones over mobile data. 
Shopping app. The product page answers what decides a purchase: price with GST, the delivery date for the shopper’s pincode, COD availability and returns. 
Shopping app. The bag shows delivery charges and the prepaid discount before checkout, which reduces abandoned carts and nudges shoppers towards paying online. 
Shopping app. Checkout offers UPI, cards, EMI, netbanking and COD within your limits, and the order status comes from the payment gateway, not the browser. 
Seller dashboard. Sellers see orders to pack, returns and their next payout on a tablet at the packing desk, without calling your team. 
Admin panel. Your team manages every order across sellers: confirming COD, acting on failed deliveries, approving returns and issuing refunds.

FAQ
Frequently asked questions
Shopify, WooCommerce or a custom build: which should we choose?
Shopify suits most new D2C brands: hosting, security and checkout are managed, and custom apps fill gaps. WooCommerce suits teams who want a self-hosted WordPress store and can maintain plugins and servers. Custom or headless builds suit B2B pricing, complex catalogues, marketplace logic or integrations that fight a platform's limits. We compare total cost over two to three years.
Can you integrate UPI, COD and more than one payment gateway?
Yes. Most stores use one primary gateway such as Razorpay, PayU or Cashfree for UPI, cards, net banking and EMI; some add a second for failover. COD is its own payment state, with confirmation flows and limits. Order status comes from server-side webhooks, not the browser redirect, so payments do not go missing when a customer closes the app mid-payment.
Do you handle GST invoices and e-invoicing?
Yes. Invoices carry HSN codes, CGST, SGST or IGST by place of supply, and returns generate credit notes. For B2B sellers above the e-invoicing turnover threshold, we connect to the Invoice Registration Portal through a GST Suvidha Provider or your accounting software to obtain an IRN and QR code. Your chartered accountant confirms the tax treatment; the system applies it consistently.
How do you migrate an existing store and protect search traffic?
We export products, customers and order history, map them to the new structure and run test imports before cutover. Every old product, category and content URL gets a 301 redirect, and titles, meta descriptions and structured data carry over. After launch we watch Search Console for crawl errors. Some ranking movement is normal; careful redirects keep it limited.
Can our catalogue also sell through ONDC or marketplaces?
Yes. On ONDC, brands usually join through a seller-side network participant, and we connect your catalogue, stock and orders to that platform. For Amazon and Flipkart we integrate their seller APIs, or a multichannel tool such as Unicommerce if you already use one. The aim is one source of truth for stock, so the same unit is not sold twice.
