Clay's ecommerce work includes a full redesign for Serena & Lily, the California luxury home furnishings retailer, built around image-forward UI and product customization tools meant to make browsing feel as considered as the products themselves. The San Francisco studio's broader client list — Slack, Coinbase, Grayscale — reflects a team built for brands competing on design quality above almost everything else.
Top 10 Ecommerce Design Agencies for 2026
Ecommerce agencies split by scale and specialty more than almost any other category — an agency built for a $2M DTC brand and one built for a $200M enterprise retailer are solving genuinely different problems, even when both call themselves "ecommerce design agencies." This ranking sorts that out, with every entry checked against the agency's own published work.
The best ecommerce agency for…
Pick the situation closest to yours. Each shortlist draws on the agencies' own stated fit below.
Premium brands where the storefront has to feel as considered as the product.
DTC brands past launch and growing fast, where the published client range is the first filter.
A first storefront and brand identity, before platform certifications matter.
Moving platforms without losing revenue, data or search rankings on the way.
Large retailers selling across regions, currencies and catalogs at once.
When the build is really an ERP, integration or product-data project.
Brands with live traffic that want design decisions tested, not guessed.
Every agency, profiled: clients, results and fit
What each agency has shipped, who it is built for, and who should look elsewhere.
Avex holds Shopify Premier Partner status and counts KITH, Hugo Boss, quip, TAG Heuer, Calvin Klein, and Khaite among its clients — the deepest luxury and premium-lifestyle roster among agencies working on the platform. The New York firm pairs Shopify Plus design and development with retention marketing, systems integration, and international expansion support.
Elogic is a platform-neutral commerce engineering firm with production experience across Adobe Commerce, Shopify Plus, BigCommerce, and commercetools — genuine range that means the firm has no platform to favor when recommending one. Its Shopify Plus wholesale portal for pet-industry brand PetHQ served more than 1,400 wholesale users and generated $1.1 million in new B2B revenue in its first year.
Vaimo has built almost exclusively on Adobe Commerce since 2008, growing into one of the largest Magento and Adobe Commerce partners in Europe with more than 500 enterprise projects delivered. The Stockholm firm's strength centers on heavy product-data work — deep PIM implementation for catalogs too large for most mid-market agencies to manage cleanly.
Fuel Made has been a Shopify Plus Partner since the program's original cohort in 2011, and works exclusively with DTC and lifestyle brands in the $1M–$15M revenue range. Documented results include a 50% conversion-rate increase for grooming brand Supply and a 72% conversion-rate lift for cocokind, delivered by a senior-only team with no junior handoffs.
Blue Stout has run conversion-rate optimization programs since 2011 and was invited into the Shopify Plus Partner program at its 2015 launch. Its published work includes a 10-week migration of iPhone case brand Speck to Shopify Plus ahead of a hard business deadline, with every account pairing conversion analysts directly with brand designers.
Mission Control is a small, fully remote studio taking on a limited number of clients at a time, with consumer products among its core industries. It doesn't carry the platform certifications or named enterprise clients of the specialists above, but suits an early-stage brand that wants senior-designer access without agency overhead.
Electric Eye works exclusively on Shopify and Shopify Plus — no other platforms — and has shipped more than 100 stores from its Columbus, Ohio base. The firm's methodology leans data-heavy, running structured A/B testing across engagements, with client testimonials specifically citing smooth handling of full rebrand-and-replatform projects.
Netalico was founded in Miami in 2013 by an engineer with an enterprise-systems background at NASA, and its published results include a 188% subscription-revenue increase for Oatly and a full Shopify Plus migration for Big Green Egg. Every developer is in-house and US-based, and the team that builds a client's store stays on for their ongoing retainer.
Eastside Co has operated as a Shopify partner since 2012 and was among the first UK agencies certified for Shopify Plus, now running more than 70 in-house specialists across offices in Birmingham, the US, and the UAE. The firm pairs Shopify Plus builds and migrations with in-house SEO, PPC, and email marketing, useful for brands wanting growth support from the same team.

How this ranking works
Every agency above is checked against its own published work — named clients, case studies, and results are things the agency has stated publicly, not secondhand directory copy. We prioritize verifiable platform depth, migration and CRO evidence, and named client results over portfolio polish alone, and we don't accept payment for placement or ranking position. See our full Methodology page for detail.
FAQ
How is this ranking different from a generic "top agencies" list?
Every fact here is checked against the agency's own site or another independently verifiable source, not pulled from a directory profile or a submitted bio. We also flag who each agency is a poor fit for, not just who it's right for — that's usually the more useful half of the decision.
How much does a custom ecommerce build cost?
It varies enormously by scope. A Shopify Plus build for a growing DTC brand often runs from the low tens of thousands into six figures depending on integrations and design complexity; enterprise builds involving ERP integration or headless architecture can run well into six figures.
Should we pick an agency based on platform experience or industry experience first?
Platform experience first, in most cases — an agency fluent in your specific platform (Shopify Plus, Adobe Commerce, headless) will avoid costly technical missteps that industry familiarity alone won't prevent. Industry-specific experience becomes the deciding factor once you've narrowed to a few platform-qualified finalists.
Is a boutique agency riskier than a large one for an enterprise build?
Not inherently — a boutique agency with senior-only staff and real platform depth (like Fuel Made or Blue Stout) can outperform a larger firm that hands your project to junior staff. Team seniority and platform track record matter more than headcount.
