Magento's power is its flexibility. Its challenge is that flexibility requires real expertise to use correctly. MercuryMinds has been delivering that expertise since 2008 — across custom builds, M1 to M2 migrations and Hyva theme implementations.
Bespoke Magento 2 and Adobe Commerce store builds — custom modules, complex catalogue structures, B2B functionality, multi-website setups and enterprise integrations. Built to Magento coding standards, performance-first.
Hyva is the modern Magento frontend — significantly faster than Luma, dramatically simpler to customise. MercuryMinds builds custom Hyva themes from scratch and converts existing Luma themes to Hyva for performance gains without full rebuilds.
M1 reached end-of-life in 2020 — stores still running it are carrying real security risk. MercuryMinds migrates from M1 to M2 or Adobe Commerce with full data integrity, custom module equivalence and SEO continuity.
Custom Magento modules for functionality that doesn't exist in the marketplace — from complex pricing rules to multi-warehouse fulfilment logic to custom ERP data flows.
Direct API integrations between Magento/Adobe Commerce and SAP, Microsoft Dynamics, Salesforce, NetSuite, HubSpot and custom ERP systems — built as production data pipelines, not fragile middleware.
Magento's default SEO configuration leaves significant organic equity on the table. MercuryMinds implements technical SEO for Magento — canonical tags, structured data, sitemap architecture, Core Web Vitals and page speed optimisation.
Hyva Theme Development
The Luma frontend that ships with Magento 2 is slow by modern standards — large JavaScript bundles, poor Core Web Vitals scores and complex customisation overhead. Hyva replaces it entirely with a lightweight Alpine.js and Tailwind CSS stack.
The result: significantly faster page loads, better Google PageSpeed scores and dramatically faster theme customisation. MercuryMinds builds custom Hyva themes and converts existing Luma themes to Hyva without disrupting the underlying Magento architecture.
Discuss a Hyva Build →Faster page loads
Hyva stores consistently score significantly higher on Google PageSpeed than Luma — directly impacting organic rankings and conversion rate.
Simpler to customise
Alpine.js and Tailwind CSS are standard modern frontend tools — easier to maintain, faster to modify, and not dependent on Magento-specific frontend knowledge.
Luma-to-Hyva conversion
Existing Magento stores can migrate to Hyva without rebuilding the backend — MercuryMinds converts the frontend layer while leaving the catalogue, integrations and custom modules intact.
Beyond the Store
Magento stores accumulate years of order data, customer behaviour, catalogue structure and ERP integration data. Most of it sits unused. MercuryMinds builds the AI layer that turns it into automated workflows — catalog enrichment, pricing intelligence, customer retention systems.
E-Commerce AI & Data Engineering →Catalog
AI Catalog Enrichment for Magento
Automated attribute extraction, description generation and taxonomy classification across your Magento catalogue — at any SKU count.
Pricing
Magento Pricing Intelligence
Competitor price tracking and repricing automation integrated with Magento's native pricing rules and customer group pricing.
Migration
Considering Shopify?
MercuryMinds actively builds on both platforms — which means the Magento-to-Shopify migration is handled by a team that knows both sides, not just the destination.
Integration
n8n & API Automation
Replace Zapier workflows with direct API pipelines built on Magento's REST and GraphQL APIs — more reliable, higher throughput, no per-task pricing.
How We Work
Fixed scope. Fixed price. Named Magento developer throughout. Every project delivers full documentation and code ownership at handover.
Current platform version, custom module inventory, integration map, performance baseline and SEO equity assessment — documented before scoping begins. For M1-to-M2 migrations this is the most important stage.
Module architecture, Hyva theme design, ERP integration schema and data migration plan — all agreed and fixed before development starts. No scope creep, no change requests mid-build.
Development on staging with staged client reviews. Custom modules tested against Magento coding standards. Integration testing against live ERP data before any go-live is scheduled.
Zero-downtime go-live with full redirect deployment for migrations. Complete technical documentation, team training and code handover. 30-day post-launch support included as standard.
Why MercuryMinds for Magento
Most Magento agencies that launched in the last five years have never seen a Magento 1 installation. MercuryMinds has been building on Magento since 2008 — through every version, every major release and the Adobe acquisition. The institutional knowledge is irreplaceable.
London Magento agency. US Magento development. UK Adobe Commerce partner. Same team, same quality standard across all four markets.
Longevity
Through Magento 1, Magento 2, the Adobe acquisition and Adobe Commerce — every version, every architectural change, every major migration pattern.
Hyva expertise
Hyva theme development from scratch and Luma-to-Hyva conversion — the fastest way to fix Magento 2 performance without a full rebuild.
Migration clarity
Considering Magento to Shopify? MercuryMinds builds on both. The recommendation you get is based on your actual requirements, not which platform we prefer.
UK & US markets
Serving UK and US merchants from Chennai, India — all project management, compliance requirements and delivery standards are calibrated for your market.
Magento Open Source (formerly Magento Community) is the free, self-hosted version. Adobe Commerce (formerly Magento Enterprise / Commerce Edition) is the commercial version — it adds B2B functionality, advanced staging and preview, enhanced search, customer segmentation and Adobe's cloud hosting platform (Adobe Commerce Cloud). Most mid-market merchants run Magento Open Source 2. Adobe Commerce is typically relevant for merchants above $10M annual revenue who need the enterprise feature set or are heavily invested in the Adobe Experience Cloud ecosystem.
Hyva is a modern frontend framework for Magento 2 that replaces the default Luma theme with a significantly faster stack built on Alpine.js and Tailwind CSS. Magento 2 stores running Luma typically score poorly on Core Web Vitals — Hyva stores score substantially higher, which directly impacts Google rankings and conversion rates. MercuryMinds builds custom Hyva themes from scratch and converts existing Luma themes to Hyva, keeping the underlying Magento backend intact.
Magento 2 development costs vary by scope. A custom store build on Magento Open Source typically ranges from $15,000–$50,000 depending on catalogue complexity, custom modules and integration count. A Hyva theme build adds $5,000–$15,000 to a standard build or conversion. Magento 1 to Magento 2 migrations are scoped individually — typically $20,000–$80,000+ for stores with significant customisation. MercuryMinds provides fixed-price scopes: no time-and-materials billing, no scope creep.
The honest answer: it depends on your business requirements, not which platform we prefer. MercuryMinds builds actively on both Magento and Shopify, so the recommendation is based on your specific situation. Shopify is typically better for merchants who want lower maintenance overhead, faster deployment and good-enough customisation. Magento is typically better for merchants with complex B2B pricing, multi-website setups, unusual catalogue structures or deep ERP integration requirements. We will tell you which one fits your operation rather than defaulting to the easier sale.
Yes. Magento's default SEO configuration misses significant organic equity — canonical tag issues, duplicate content from layered navigation, poor structured data implementation and slow page speed. MercuryMinds implements technical Magento SEO as part of builds and as standalone engagements: canonical tag audit and fix, structured data implementation, Hyva performance improvements for Core Web Vitals, XML sitemap architecture and crawl budget optimisation.
Yes. MercuryMinds serves Magento and Adobe Commerce merchants in the UK, USA, Canada and Australia. The delivery team is based in Chennai, India. For UK merchants: GDPR compliance, VAT configuration and UK payment gateway integrations are handled as standard. For US merchants: US tax configuration, US payment gateways and CCPA compliance where applicable. Sales enquiries receive a response within 24 hours.
