A beautiful online store that can't take a payment at 11 pm on a sale night is a very expensive brochure. That's the difference between someone who can install a shopping cart and an ecommerce website developer who understands selling.
Design still matters. But most of what decides whether a store makes money sits behind the product page: checkout, payments, shipping, stock and speed.
The short answer
A good ecommerce website developer does more than design the store. They help you choose the right platform, set up payments, shipping and tax correctly, make checkout quick on a phone, and leave you able to run the store without calling them for every change. Check those five things before you look at the price.
Start with the platform, because it decides the cost
| Platform | How it works | Best for | Watch for |
|---|---|---|---|
| Shopify | Hosted for you, on a monthly subscription | Getting a standard store live quickly | Monthly fees and paid apps add up, and deep customisation is limited |
| WooCommerce | A free plugin for WordPress, on hosting you pay for | Small to mid-sized catalogues and content-led brands | It needs regular updates and decent hosting |
| Custom build | Built for your business, for example on Next.js | B2B portals, marketplaces, unusual pricing or workflows | Higher upfront cost and a longer build |
A developer who works on only one platform will recommend that platform. Ask why it suits your business in particular, and what would have made them suggest something else.
What a store needs beyond design
Payments. A gateway such as Razorpay, PayU or Cashfree, with UPI, cards and cash on delivery if your customers expect it. Ask what happens when a payment fails halfway, and how refunds are issued.
Shipping. Courier integration, pin-code checks, shipping rates and tracking messages by email or WhatsApp.
Tax and invoices. GST-compliant invoices generated automatically, with the right HSN codes.
Stock. Variants such as size and colour, stock counts that update with each order, and low-stock alerts.
Speed. Compressed product images and a checkout that takes as few taps as possible on a phone.
Search and filters. Once you have more than a few dozen products, shoppers need to narrow them down.
Tracking. Purchases, abandoned carts and ad conversions recorded properly, so you know which marketing pays.
If you sell to other businesses
B2B ecommerce website design is a different job from a consumer store. Business buyers expect:
- Prices visible only after login
- Different price lists for different customers
- Minimum order quantities and bulk price tiers
- A “request a quote” option alongside “add to cart”
- Credit terms and purchase orders, not only online payment
- One-click reordering from past orders
- GST details saved on the account
Ready-made themes rarely handle this well. It usually calls for a custom build or careful extension of an existing platform.
If you want a marketplace
A multi-vendor marketplace is three products in one: the site buyers see, the panel sellers use, and the admin system you run. It needs seller onboarding and verification, commission rules, split payouts, and a way to handle disputes.
Budget and plan for it as a software product, not as a bigger shop.
Eight questions to ask an ecommerce website developer
- Which of your stores are live and taking orders, and can I place a test order on one?
- Which platform do you recommend for me, and why?
- Who sets up the payment gateway, and in whose name? (It should be yours.)
- How will shipping and cash on delivery work?
- Can I upload products in bulk from a spreadsheet?
- How quickly will product pages load on a phone?
- What gets tracked: purchases, abandoned carts, ad conversions?
- What will I pay each month after launch for the platform, apps, hosting and support?
What it costs
Price guides published in 2026 put a standard online store in India at roughly ₹50,000 to ₹3 lakh. Custom builds start at around ₹1.5 lakh and climb steeply for large catalogues, B2B portals and marketplaces.
The number moves with the count of products and variants, how much of the design is custom, the integrations you need, and whether old data has to be moved across. Always ask for the monthly running cost as well as the build price.
Red flags
- A portfolio made up entirely of screenshots
- No mention of testing the checkout
- “Unlimited products” presented as a selling point
- The payment gateway or domain held in the developer's account
- Silence about what happens after launch
Frequently asked questions
Shopify, WooCommerce or custom?
Shopify if you want speed and little maintenance. WooCommerce if you want control and lower fixed fees. Custom if you're building a B2B portal or a marketplace.
How long does it take to build an ecommerce website?
A standard store takes a few weeks. A custom build commonly takes two to three months, and a marketplace takes longer.
Can I manage the store myself afterwards?
You should be able to add products, change prices, run offers and process orders without help. Ask for a training session before handover.
Do I need a mobile app as well?
Not at the start. Get the mobile website right first, and consider an app once you have repeat customers.
