E-commerce Development Guide for Indian Businesses

Guide E-commerce development: how an online store is built

An online store is six systems working together: catalogue, cart and checkout, payments, order management, shipping, and accounts. A platform such as Shopify gives you all six on day one; a custom build gives you control over each. This guide explains where each choice fits and links to WavX's e-commerce services, integrations and guides.

The six parts of an online store

Part

What it does

Where projects go wrong

Catalogue

Products, variants, prices, stock

Variants and stock modelled too simply for how the business really sells

Cart and checkout

Turns a visit into an order

Too many steps; delivery charges shown late

Payments

Collects the money

Payment confirmations not verified; refunds handled by hand

Order management

Tracks each order from paid to delivered

No single place that shows an order's true state

Shipping

Books couriers, prints labels, tracks parcels

Cash-on-delivery returns and failed deliveries not planned for

Accounts and tax

Invoices, GST, reconciliation

Orders retyped into accounting software

A store is only as good as the weakest of the six. Most of the work in a serious build is in the last four, which customers never see.

Platform or custom

A hosted platform gives you all six parts immediately, at a monthly fee, within the platform's rules. See the Shopify development guide .

A custom store costs more to build and nothing per month in platform fees, and does exactly what you specify. It is the right choice when the selling model does not fit a platform: B2B ordering portals, marketplaces, quick-commerce apps.

Headless keeps a platform's back end and replaces the storefront. It suits few stores; see headless commerce before choosing it.

What to settle first

How customers pay, and what share will be cash on delivery. See payment gateway integration .

Who ships, and what happens when a parcel comes back.

Where orders go for accounting.

What the store must do in year two that it does not need on day one.

UPI Autopay How a UPI Autopay integration works through a payment gateway: mandate registration, the ₹15,000 rule, pre-debit notices, retries and subscription states.

Shiprocket What a Shiprocket API integration involves: pushing orders, assigning a courier and AWB, tracking by webhook, and acting on non-delivery reports before they return.

GST e-invoicing How a GST e-invoice integration works: invoice JSON to the IRP, IRN and signed QR back, cancellation rules, API access through a GSP, and what breaks.

When something is going wrong

Orders not syncing to Tally or ERP Orders from your online store are missing, duplicated or wrong in Tally or your ERP. The six usual causes, a check for each using one failed order, and what a reliable sync needs.

Frequently asked questions

Should I use Shopify or build a custom store?

Use a platform if your store sells in the usual way: products, a cart, a checkout. Build custom when the way you sell is itself unusual, such as negotiated prices, complex bundles, a marketplace with many sellers, or ordering rules a platform cannot express. Most new stores should start on a platform.

What does an e-commerce website cost in India?

It depends on the route. WavX has published planning ranges for each in its e-commerce cost guide, and the website cost calculator gives a range from your own choices.
