Retail and ecommerce website and app development for Indian sellers
Online stores, catalogues and retail apps that handle COD, returns, GST invoices and stock across shop and web.
Selling online in India is different from selling in a mall. A large share of buyers still choose cash on delivery, return rates are high in some categories, and a shopper compares price on three apps before paying. Retail and ecommerce website and app development has to account for these, along with GST invoices and courier delays.
NioDelta is a Pune studio that builds stores on Shopify and WooCommerce, and custom stores when a template stops fitting. We also build inventory tools and apps for shops that sell offline and online. We help you choose the smallest build that sells. We recommend the smallest build that can sell, then grow it from real orders.
Where Indian retail and D2C sellers lose money
COD orders that never get accepted
Cash on delivery brings orders, and also returns to origin. Without phone or WhatsApp confirmation and pincode checks, shipping costs eat the margin.
Stock out of sync
The shop, the website and the marketplace each show a different stock count. Customers pay for items that are not there, and staff apologise by phone.
Slow store on mobile
Most shoppers use mid-range Android phones. Heavy themes and unoptimised product images lose customers before the first product loads.
Catalogue work never ends
Hundreds of products with variants, sizes and prices are updated by hand. A mistake in one price list can create losses for a week.
What we build for retail and ecommerce businesses
Shopify and WooCommerce stores
Fast storefronts with product pages, variants, coupons, Razorpay or other gateways, and shipping rules by pincode. Chosen when you want to launch quickly and manage products yourself.
Custom ecommerce platforms
When your pricing, bundles or B2B rules do not fit a template, we build a custom store with its own admin and rules, owned by you.
COD and returns workflow
Order confirmation through WhatsApp, pincode serviceability, partial prepayment for risky orders and a clear return request flow.
Inventory and billing sync
Connect the store to your billing or POS software so stock and prices match. We use the tool's API where it exists, or build a simple import where it does not.
Shopping app
A Flutter or React Native app with login by OTP, saved addresses, order tracking and push notifications, for sellers with repeat customers.
Catalogue sites for wholesalers
For sellers who quote rather than sell online, a product catalogue with enquiry basket, price on request and WhatsApp order sharing.
How a retail build runs
Discover
We review your catalogue, courier setup, return rate and where your orders come from today. We note which tools already hold your stock and billing.
Define
We choose the platform, set shipping and tax rules, and list integrations. The written quote separates what is a template change from what is custom code.
Design
Product and checkout pages are designed for thumb use on a small screen. Image sizes and page weight are budgeted from the start.
Build
We build, import your catalogue, connect payments and shipping, and test the full order path, including COD and a refused return.
Ship & extend
We go live with redirects and schema in place, then support you for a month. Marketplace sync or an app can follow once orders justify it.
What it costs
An ecommerce store starts at ₹75,000 and a shopping app at ₹2,00,000. Inventory sync, marketplace connectors and custom pricing rules are quoted after a discovery call.
- Number of products and variants
- Payment and courier integrations
- Billing or POS sync

Questions we get asked
Shopify or a custom store?
Choose Shopify when your catalogue and checkout are standard and you want to launch quickly. Choose custom when pricing rules, bundles or B2B workflows do not fit. We recommend after seeing your products, not before, and we say so in the quote.
Can you reduce COD returns?
Partly. We can add pincode checks, WhatsApp or call confirmation, and partial advance payment for high-risk orders. Software cannot remove returns entirely, but it can cut the avoidable ones. Customers also get a clean refund path, which lowers support calls after a cancelled order.
Can the store sync with our billing software?
Often yes. If your billing or POS tool offers an API or scheduled export, we connect it for stock and prices. Where it does not, we build a reliable import. We check this in discovery before quoting.
Do you handle GST invoices?
Yes. The store can generate GST-compliant invoices with HSN codes and place-of-supply logic based on your registration. Your accountant should confirm the tax settings before launch. Order and stock records stay consistent, so the same item is not sold twice during a busy sale.
Do we need a mobile app?
Usually not at the start. A fast mobile site covers most buyers. An app helps when customers reorder often, such as grocery, pharmacy or apparel loyalty. We will tell you honestly if it is too early.
Do you list products for us?
We import your catalogue from a spreadsheet during the build. Ongoing product photography, copy and listing are done by your team, or we can train them on the admin panel. Bulk import tools save most of the effort when the catalogue is large, and prices can be updated in one upload.
