E-Commerce & Shopify Development Services

We launch and scale Shopify stores and custom e-commerce platforms — from theme customization to headless storefronts with 2–3x conversion improvements.

What It Includes

Shopify Store Setup & Theme Development

Custom Shopify 2.0 themes with Online Store 2.0 sections, metafields, and app integrations. We build mobile-first storefronts that load in under 3 seconds — a direct factor in reducing cart abandonment rates.

Shopify App & Extension Development

Private and public Shopify apps using Remix and the Shopify Admin API. Checkout UI extensions, post-purchase upsells, and custom discount logic that native Shopify cannot handle out of the box.

Custom E-Commerce Platforms

Headless commerce with Next.js storefronts connected to Shopify, Medusa, or custom backends. Full control over checkout UX, product configurators, and B2B pricing tiers for wholesale clients.

Payment & Shipping Integration

Stripe, Razorpay, PayPal, and Shopify Payments setup with multi-currency support. Real-time shipping rate calculation via ShipStation, FedEx, and Delhivery APIs for India, US, and AU markets.

Analytics & Conversion Optimization

Google Analytics 4, Meta Pixel, and Hotjar heatmaps configured for e-commerce funnels. A/B testing on product pages and checkout flows — our clients typically see 15–30% conversion lifts within 90 days.

Our Process for E-Commerce & Shopify

01

Store Strategy & Catalog

Product taxonomy, pricing strategy, and platform selection (Shopify vs. custom). We audit competitor stores and define the MVP feature set for launch.

02

Design & Theme Build

Custom theme design in Figma, then Liquid/JSON template development with Shopify 2.0 sections. Stakeholders review on a staging store before products go live.

03

Integration & QA

Payment gateway testing, inventory sync, email automation (Klaviyo/Omnisend), and order fulfillment workflow validation across test transactions.

04

Launch & Growth

Domain setup, SEO configuration, Google Merchant Center feed, and post-launch conversion monitoring. We provide a 30-day optimization sprint after go-live.
