The modules

What the software does on day one.

We have built each of these before, so your first version starts from working modules rather than a blank repository. You pick what you need and we shape it around how your business already runs.

01Catalogue and pricing engineProducts, variants, bundles and the pricing rules a store product cannot express: customer-specific rates, slabs, contract prices and minimum order quantities.
02Storefront and checkoutA fast storefront rendered on the server, with a checkout that survives a weak connection and opens with UPI rather than a card form nobody wanted.
03Inventory and fulfilmentStock across warehouses and channels, allocation rules, picking and packing, courier integration and returns, so what the site sells is what you can actually ship.
04Orders, payments and invoicingThe order lifecycle with UPI, cards and cash on delivery, GST invoices generated at order time, refunds, and reconciliation when the courier settles.
05Seller and vendor toolsFor marketplaces: onboarding and KYC, per-seller catalogues and pricing, commission rules, split payouts, order routing and dispute handling.
06Operations and adminThe screens your team lives in during a sale, built for speed rather than for a demo, plus roles and permissions that survive an audit.

Where AI pays for itself

The AI features worth adding, and why.

Search that understands meaningSo a query like something warm for a two year old returns the right products instead of nothing, which is where most catalogue searches quietly fail today.
Recommendations from your own dataBuilt on what people actually buy together in your store rather than a generic widget, and measured against a control group so you know what it added.
A support agent that knows the orderReading the order, the policy and the shipment status before answering, escalating when it should, and absorbing the where is my order messages that follow every sale.

Who this is for

Sellers who have run into the edge of a store product. In practice that is D2C brands where page speed and content have become the growth lever, B2B distributors whose customers each have negotiated prices, and marketplace operators with sellers, commissions and payouts to manage.

If you are selling an ordinary catalogue and want to be live in weeks, you do not need this page. You need e-commerce development, and Shopify with a custom theme will beat anything we could build for you at that stage.

RULES NOBODY SELLSYour own platform

The middle option is underrated and it is where most brands should land. A fast storefront you fully control, sitting in front of a hosted commerce backend that keeps handling payments, taxes and the parts you gain nothing from rebuilding.

Moving to the third step is a real commitment: you now own the roadmap, the upkeep and the on-call. It is worth it when the rules that make you money cannot be expressed any other way.

The four reasons that genuinely justify a platform build

The reasonWhat it looks like
Pricing that is per customerNegotiated rates, slabs, contract prices, credit limits, approval flows
Many sellersOnboarding, commissions, split payouts, routing, disputes
Fulfilment rules of your ownMulti-warehouse allocation, made to order, partial shipments, serial tracking
The catalogue itself is unusualConfigurable products, dimensions, rentals, subscriptions with real variation

If none of those describe you, the honest answer is that a platform build is an expensive way to get a store, and we will say so on the first call even though it is the larger project for us.

Built for how India buys

Whichever route you take, the commerce realities here do not change:

  • Cash on delivery, which is still a large share of orders in many categories and changes everything downstream: address verification, fraud rules, partial prepayment, courier reconciliation and returns.
  • UPI first. The checkout should open with the method most of your customers already use.
  • GST invoices with correct place of supply and HSN codes, generated at order time rather than assembled later.
  • Courier reality, meaning serviceability by pincode, weight and dimension rules, and integrations that make tracking automatic.
  • Modest phones on weak connections, because a checkout that assumes fast Wi-Fi loses orders every day without ever showing you an error.

Talking to the systems you already run

On a platform build, integration is usually the actual point. Stock, prices, customers, orders and invoices have to stay in step with an ERP, a warehouse system or your accounting, whether that is Tally, SAP, Zoho or something built in-house.

The decision that matters is which system owns each piece of data. Two systems both convinced they own stock is the most common way an e-commerce integration fails, and it is a conversation we have in discovery rather than in production.

The AI that earns its place in commerce

Search that understands meaning rather than matching words, because a catalogue search returning nothing is a sale lost silently. Recommendations built on what people actually buy together in your store. And a support agent that reads the order, the policy and the shipment status before answering, which absorbs the message volume that follows every sale day.

Each ships behind a feature flag with a control group, so the effect on conversion is a number rather than a claim. The engineering is described on AI integration.

What it costs and how long it takes

A first sellable version takes 12 to 16 weeks, and a full platform with marketplace or B2B features and ERP integration 20 to 24. The price is fixed after discovery.

If a companion shopping app is part of the plan, see mobile app development. If your platform is really a SaaS product other businesses will pay for, that is web and SaaS development.

Frequently asked questions

Common questions about e-commerce platforms.

How much does a custom e-commerce platform cost in India?

A headless storefront on a hosted commerce backend typically costs 8 to 20 lakh. A full custom platform with its own catalogue, pricing and order engine runs 20 to 60 lakh depending on the rules and integrations. A Shopify store with a custom theme costs a fraction of either and is the right answer more often than not.

How is this different from your e-commerce development service?

Our [e-commerce development](/services/ecommerce-development) service covers Shopify, headless storefronts and store migrations, which is what most sellers need. This page is for the cases a store product cannot hold: B2B pricing rules, multi-warehouse allocation, marketplaces with sellers to pay, or a catalogue model that does not fit how Shopify thinks.

When should we build our own platform instead of using Shopify?

When your pricing, bundling or fulfilment rules cannot be expressed in a product, when you run a marketplace with commissions and payouts, when B2B customers each have negotiated rates, or when platform fees on your volume have grown past what a build and its upkeep would cost. Outside those cases, buy.

Do you build B2B e-commerce with customer-specific pricing?

Yes, and it is one of the clearest reasons to build. Price lists per customer or group, slab and quantity breaks, contract rates, minimum order quantities, credit limits, purchase orders and approval flows, with the catalogue itself differing by who is logged in.

Do you build multi-vendor marketplaces?

Yes. Seller onboarding and KYC, per-seller catalogues and pricing, commission rules, split payouts, order routing across sellers, returns and dispute handling, plus the admin tooling your operations team needs to run it every day.

Can it integrate with our ERP, warehouse or accounting system?

Yes, and on a platform build this is usually the point. Stock, prices, customers, orders and invoices sync with Tally, SAP, Zoho or whatever you run, in the direction that makes one of them the source of truth. We agree which system owns each piece of data before writing any of it.

Will it handle UPI, cash on delivery and GST invoices?

Yes. UPI, cards, wallets, net banking and EMI through Razorpay, PayU or Cashfree, cash on delivery with its order rules and courier reconciliation, and GST invoices with correct place of supply and HSN codes generated at order time.

How long does it take?

A first sellable version takes 12 to 16 weeks, and a full platform with marketplace or B2B features and ERP integration 20 to 24. We put a working storefront in front of real orders as early as possible, because a catalogue behaves differently once customers are in it.
