Zethic is an ecommerce website development company in Kolkata building stores for a market that sells through some of the oldest trade routes in the country and some of its newest storefronts. Burrabazar moves wholesale volumes that predate most platforms built to sell them online, while Sector V runs on a tech workforce that shops fast, on a phone, and gone the moment checkout slows down.

What we build for Kolkata brands
Zethic's ecommerce development services cover the full range a Kolkata seller might need across the top ecommerce industries, whether the buyer is a Burrabazar wholesaler, a Sector V D2C shopper, or a trading partner across the border.
Checkout and pricing shaped around who's actually buying.
Bulk order minimumsNegotiated pricingSingle-page checkoutBuyer-type architecture
Checkout and pricing logic shaped around who's actually buying: bulk order minimums and negotiated rates for a wholesale trader, a quick single-page checkout for a retail shopper on a phone.
Multi-currency checkout and export paperwork built into the flow.
Multi-currency checkoutCross-border payment routingExport documentationTrade-corridor logic
Catalog and payment logic that works in more than one currency, with the export paperwork for trade into Bangladesh and the Northeast built into the order flow rather than handled separately.
Multi-vendor and B2B marketplaces built for Kolkata's trading houses.
Seller onboardingCommission logicTiered quantity discountsCredit-term settlement
Seller onboarding, commission logic, and payment routing for marketplaces spanning multiple wholesale sellers or brand partners, plus tiered quantity discounts, credit-term settlement, and a procurement workflow buyers already recognise.
WooCommerce, Shopify, and a managed move from your old platform.
WooCommerce developmentShopify developmentAPI & ERP integrationPlatform migration
Custom product configuration and checkout logic with our WooCommerce development services for full code ownership, or theme setup and headless builds via our Shopify development services for a tight launch date, plus payment, ERP, and CRM systems tied together and a tracked migration off your existing platform.
Ecommerce, our team for turning a Kolkata catalog into a store that holds up.
Why teams choose us in Kolkata.
A wholesaler settling accounts on credit terms and a Sector V shopper paying instantly are, in effect, two different products sharing one storefront.
RBI's Payment Aggregator norms, the DPDP Act, and GST-compliant invoicing ship with the first sprint rather than getting bolted on later.
Catalog size and buyer mix decide whether the build is WooCommerce, Shopify, headless, or fully custom, not whichever is fastest for us to ship.
After launch, the same people keep monitoring the store, fixing bugs, and building new features, rather than handing the account off to a support desk.
Buyer mix comes first, not the platform. Each stage moves in sequence, from discovery through to a month of monitoring after go-live.
Book a discovery call{ 01 }· Week 1
The first question is who's buying: wholesale, cross-border, or retail, before catalog structure and pricing logic get mapped and a platform is chosen.
{ 02 }· Week 2 to 3
The screens a buyer actually uses get built out in Figma once the catalog logic is settled, and nothing moves to development until every screen has sign-off.
{ 03 }· Week 4 to 8
What gets coded matches the approved design point for point, and a CMS handover means your team can update products, prices, and stock without a ticket.
{ 04 }· Final 2 weeks
The store is tested against payment methods, devices, and a simulated Durga Puja rush, then launched with a rollback plan and a month of close monitoring.
Questions, answered.
Most web design agencies finish once the site looks right on screen. An ecommerce website development company in Kolkata still has work to do: payment gateway wiring, GST-compliant checkout, inventory tracking, and the backend plumbing that keeps orders and accounting from drifting apart.
Yes. This is common work for wholesale traders across the city, and it usually involves bulk pricing tiers, minimum order quantities, and credit-term checkout built in from the start rather than a retail template stretched to cover trade buying.
Yes. Multi-currency checkout, cross-border payment routing, and the documentation that comes with trade across the eastern border are common requests from Kolkata businesses with an established export base.
Expect roughly 8 to 12 weeks for a straightforward WooCommerce or Shopify build. A custom B2B platform with cross-border requirements takes longer, generally 4 to 6 months, mostly because of how many outside systems and compliance checks it has to pass through.
The city matters less here than the platform and how many systems it needs to talk to. A mid-size WooCommerce or Shopify build sits within our ecommerce website development cost in India range, and since WooCommerce runs on WordPress, our WordPress website development cost guide covers the CMS side; custom B2B or cross-border platforms cost more given the added compliance and architecture.
Yes. The same senior team also builds our ecommerce development company in Bangalore, plus similar trade and B2B-heavy stores for teams in Lucknow.
