06 — E-commerce Development

E-commerce built for the brand in front and the operation behind.

An online store is two products: the storefront customers see and the operation the team runs behind it. We build both — storefronts that load fast and present products properly, and catalogue, inventory, order and promotion tools that fit how your team actually fulfils orders.

    Workshops with the people who run the process today. We map how work actually moves, where it stalls and what the system must never get wrong.

    Data model, service boundaries, hosting, security model and the trade-offs behind each choice — reviewed with your team before code starts.

  4. 04 · Build

    Short sprints with a working demo every week. Code review on every change, automated tests on the paths that carry money or data.

  5. 05 · Validate

    Functional QA, role-by-role acceptance, performance checks and a security pass before anything reaches production users.

  6. 06 · Scale

    Staged rollout, monitoring and a support window. Then the backlog of improvements that only real usage reveals.

FAQs

Common questions.

Should we use Shopify or build custom?

If your catalogue and fulfilment are standard, a hosted platform is usually right. Custom or headless makes sense when brand presentation, B2B pricing or operational rules outgrow what the platform allows.

Which payment gateways do you integrate?

Stripe and Razorpay most often, and others on request depending on your markets.

Can you migrate our existing store without losing SEO?

Yes. We map URLs, set redirects and preserve metadata as part of the migration plan.

Do you build the admin side too?

Yes. Catalogue, inventory, orders, customers, promotions and reporting.

How much does e-commerce website development cost in India?

Cost depends on catalogue complexity, integrations (payment, shipping, ERP), design depth and whether you need an app. We scope and estimate after a short discovery.

Shopify or custom e-commerce development?

Shopify is often right for standard catalogues. Custom or headless development makes sense for B2B pricing, marketplaces, complex fulfilment or when brand presentation needs full control.

Which payment gateways do you integrate in India?

Razorpay, Cashfree, PayU and Stripe are common choices, along with UPI, cards, net banking and cash on delivery options.

Can you integrate shipping partners like Shiprocket or Delhivery?

Yes, through their APIs for rate calculation, label generation and tracking updates.
