Shopify UX Design & Development

Most ecommerce stores are designed for launch day. We design for what comes after — the traffic spikes, the product catalog expansions, the market entries, and the operational complexity that enterprise brands actually face.

Our Shopify Plus UX design and development practice sits at the intersection of consumer psychology, conversion science, and technical architecture. We don't hand off wireframes to a development team — strategy, design, and engineering work together from day one, which means the experience your customers see is built on a foundation that actually supports it.

Shopify Plus Platform Migrations

Platform Migrations break more than most agencies admit — data lost, redirects missed, custom functionality left behind. We've done this enough times to know exactly where things go wrong — and how to make sure they don't.

Our Shopify Plus migration engagements covers the full scope: platform audit, data architecture, URL mapping, third-party integrations, custom feature rebuilds, and performance benchmarking before a single page goes live. We don't cut corners on QA and we don't hand you a launch checklist and disappear. Every migration we run is senior-led, documented end to end, and stress-tested against your real traffic and operational load.

Whether you're moving from Magento, Salesforce Commerce Cloud, BigCommerce, or a custom-built platform, we bring the technical depth and Shopify Plus fluency to get you there without losing what you've built.

International Expansion

Avex architects international Shopify environments by defining how localization, multi-language content, multi-currency pricing, taxes, and fulfillment operate at the system level. We design around merchant-of-record requirements, regional compliance, and market-specific rules while maintaining centralized control over data, analytics, and operations.

The result is a global Shopify architecture that supports local variation without fragmenting performance, allowing brands to scale internationally with confidence.
