Shopify Development Services
Most Shopify agencies pick one lane — theme builds or app development or migrations. MercuryMinds covers the full stack, from a custom Shopify Plus store to an AI-powered catalog pipeline on top of it.
Bespoke Shopify store builds — custom themes, unique checkout flows, third-party integrations and functionality that the app store doesn't cover. Built to your specification, not a template dressed up.
Custom Shopify themes built from scratch or heavily modified from a base. Performance-first — Core Web Vitals compliant, mobile-optimised, conversion-tested before handover.
Custom checkout extensibility, B2B functionality, multi-storefront management, Shopify Functions and headless builds for high-volume merchants on Shopify Plus.
Shopify public and private app development — for functionality the app store doesn't provide or when off-the-shelf apps create performance problems at scale.
Direct API integrations between Shopify and your ERP, WMS, CRM, accounting platform or supplier feeds — replacing fragile Zapier workflows with production-grade data pipelines.
Full-stack migrations from Magento, WooCommerce, X-Cart and other platforms — products, customers, orders, SEO URLs and integrations — with zero data loss and SEO continuity guaranteed.
Beyond the Store
After 17+ years of Shopify development, MercuryMinds builds the AI and data engineering layer that sits on top of the platform — automating the work that slows teams down as catalogue and order volume grows.
One team handles the build and the intelligence layer. No briefing three different agencies. No integration gaps between the store and the data work.

How We Work
Fixed scope. Fixed price. Named project lead throughout. You own everything at handover — code, theme, integrations, documentation.
We map your current platform, integration requirements, catalogue size and performance targets. Scope is agreed and fixed in writing before any development starts — no scope creep, no surprises.
Theme architecture, data model, integration design and third-party API mapping — all signed off before build. If you're migrating, the data migration plan is produced and approved at this stage.
Development on a staging environment with staged reviews. ERP and system integrations tested against live data before full deployment. Shopify Plus functionality validated against your specific checkout and B2B requirements.
Go-live with zero-downtime deployment. Full documentation, team walkthrough and code handover. 30-day post-launch support included. Everything is yours — no proprietary lock-in.
Why MercuryMinds for Shopify
Most Shopify agencies only know Shopify. MercuryMinds has been building on Magento, WooCommerce and X-Cart since 2008 — which means migrations are handled without guesswork and the gaps between platforms are known before they become problems.
1,000+ stores built across five platforms. The Shopify work benefits from every one of those builds.
Platform depth
Since 2008 across Shopify, Magento, WooCommerce and X-Cart — the edge cases on your project have been seen and solved before.
Migration expertise
Migrating from Magento or WooCommerce to Shopify? We built on both platforms. The data model, the custom fields, the edge cases — already known.
AI layer
Catalog enrichment, programmatic SEO, pricing intelligence — built on top of your Shopify data by the same team that built the store. No briefing multiple agencies.
US & UK focus
All Shopify development is scoped, managed and delivered for US, UK, Canadian and Australian merchants — market-specific performance standards, not a generic global template.
A Shopify development agency builds, customises and integrates Shopify stores for ecommerce businesses. This covers custom theme development, bespoke functionality beyond what the app store offers, ERP and CRM integrations, Shopify Plus builds for high-volume merchants, custom app development and migrations from other platforms. MercuryMinds also builds the AI and data engineering layer on top — catalog automation, programmatic SEO, pricing intelligence — so the same team handles both the store and the intelligence systems that run on it.
Shopify development costs vary significantly by scope. A custom theme build for a standard Shopify store typically ranges from $5,000–$20,000 depending on complexity and custom functionality. Shopify Plus builds with custom checkout, B2B functionality and ERP integrations typically start from $20,000. Migrations from Magento or WooCommerce are scoped individually based on catalogue size, custom module complexity and integration count. MercuryMinds provides fixed-price scopes — no time-and-materials billing, no scope creep surprises.
Shopify Plus is Shopify's enterprise tier — designed for high-volume merchants typically processing over $1M per year in revenue. Key differences include custom checkout extensibility via Shopify Functions, multi-storefront management, B2B and wholesale functionality, higher API limits and a dedicated merchant success manager. MercuryMinds builds custom Shopify Plus stores including custom checkout flows, B2B price lists, automated fulfilment integrations and headless implementations.
Yes. AI capabilities can be added to an existing Shopify store without a full rebuild. The most common starting points are AI catalog enrichment (automating description generation, attribute extraction and taxonomy at scale), programmatic SEO (generating keyword-targeted landing pages from existing product data) and pricing intelligence (real-time competitor monitoring and repricing). MercuryMinds scopes the right starting point based on your current data quality, SKU volume and the manual work your team is spending the most time on.
A full-stack migration to Shopify covers five stages: platform audit and data export, URL mapping and redirect file creation, Shopify store build and data import, QA and integrity validation (record count matching, redirect testing, integration testing) and go-live with 30-day post-launch monitoring. MercuryMinds has migrated 100+ stores from Magento, WooCommerce and X-Cart to Shopify — with zero data loss and full SEO continuity on every completed project.
Yes. MercuryMinds serves Shopify merchants in the USA, Canada, UK and Australia. The delivery team is based in Chennai, India — all development is scoped, managed and delivered to the performance and compliance standards of these four markets, including UK VAT requirements, GDPR compliance and US payment gateway integrations.
