Top 6 Ecommerce Web Development Agencies for 2026

This page is about the build itself — the platform decision, the migration, the technical execution that determines whether a launch goes smoothly or turns into a six-month fire drill. Every agency here is ranked on real, named build and migration work, not general commerce marketing.

Every agency, profiled: migrations, builds and fit

Named replatforms, the platforms each agency builds on, and who should look elsewhere.

1. Domaine

domaineworldwide.com

New York, NYShopify-exclusive since 2015~150 migrations, 750+ launches

Domaine has focused exclusively on Shopify since 2015 and has migrated nearly 150 brands from legacy platforms — including Salesforce Commerce Cloud and Adobe Commerce — to Shopify, with more than 750 Shopify sites launched across its portfolio. Named results include a 22.1% average-order-value increase for fragrance house Creed and a 38% AOV increase for Laura Mercier following migration, and its Timex replatform modernized ecommerce across the US, Canada, UK, and Europe from a single legacy SFCC instance.

Best forGlobal or multi-region enterprise brands migrating off a legacy platform onto Shopify.

Not forBrands that want to evaluate non-Shopify platforms — Domaine's whole practice is built around one platform exclusively.

2. Netalico Commerce

netalico.com

Miami, FLFounded 2013In-house, US-based developers

Netalico was founded in Miami in 2013 by an engineer with an enterprise-systems background at NASA, and its published migration results include a 188% subscription-revenue increase for Oatly and a full Shopify Plus replatform for Big Green Egg. Every developer is in-house and US-based, and the same team that builds a client's store stays on for their ongoing retainer rather than handing off to a separate support team.

Best forMid-market to enterprise DTC brands ($2M–$50M GMV) that want one team handling the migration and everything after.

Not forBrands below that GMV range — Netalico's engineering-led model and pricing assume real existing scale.

3. Blue Stout

bluestout.com

Portland, ORDevelopment & CRO since 2011Shopify Plus Partner since 2015

Blue Stout has run development and conversion-rate optimization programs since 2011 and was invited into the Shopify Plus Partner program at its 2015 launch. Its published migration work includes a 10-week move of iPhone case brand Speck to Shopify Plus ahead of a hard business deadline, with development decisions made alongside live conversion data rather than guessed at and validated after launch.

Best forEstablished DTC brands that want their build and their conversion optimization run by the same team from day one.

Not forNewer brands without meaningful existing traffic — Blue Stout's process is built to iterate against live data it doesn't yet have.

4. Electric Eye

electriceye.io

Columbus, OHShopify & Shopify Plus only100+ stores shipped

Electric Eye builds exclusively on Shopify and Shopify Plus, having shipped more than 100 stores from its Columbus, Ohio base. The firm's senior strategists, designers, and developers work inside one platform's app ecosystem and theme architecture rather than splitting attention across several, and client testimonials specifically cite smooth technical handling of full replatform projects.

Best forDTC lifestyle brands in fashion, home goods, or accessories that want deep single-platform Shopify expertise.

Not forBrands evaluating platforms other than Shopify, or those needing broader multi-platform engineering range.

5. Fuel Made

fuelmade.com

Portland, ORShopify Plus Partner since 2011Senior-only teams

Fuel Made has been a Shopify Plus Partner since the program's original 2011 cohort, with every project handled by a dedicated strategist, designer, developer, and project manager — all senior-level, with no junior handoffs. The firm's site rebuilds average a 22% conversion-rate lift and 15% revenue lift, and its client work spans grooming, apparel, and accessories brands in the $1M–$15M revenue range.

Best forGrowing DTC and lifestyle brands that want a boutique Shopify Plus build with measurable conversion results baked into the process.

Not forEnterprise-scale retailers — Fuel Made's boutique model is calibrated for a specific mid-market range.

6. Classy Llama

classyllama.com

Springfield, MOAdobe Commerce since 2007125+ sites, 400+ integrations

Classy Llama has worked with Adobe Commerce since 2007 and has completed more than 125 commerce sites and 400-plus integrations, positioning itself as a platform-agnostic replatform agency working across Adobe Commerce, BigCommerce, and Shopify depending on client fit. That range gives the firm an honest basis for recommending a platform rather than defaulting to whichever one it knows best.

Best forMid-market brands that want an honest, platform-agnostic recommendation before committing to a specific build.

Not forBrands that already know their platform and just want a specialist — Classy Llama's value is partly in the platform-comparison step itself.

Method

How this ranking works

Every agency above is checked against its own published work — named clients, migration results, and platform certifications are things the agency has stated publicly, not secondhand directory copy. We prioritized verifiable migration and build track record over general commerce marketing claims, and we don't accept payment for placement or ranking position.

FAQ

How do we choose between a single-platform specialist and a platform-agnostic agency?

A single-platform specialist (like Electric Eye or Fuel Made for Shopify) brings the deepest expertise if you've already committed to that platform. A platform-agnostic agency (like Classy Llama) is the better starting point if you haven't decided yet and want an honest comparison before committing.

What actually goes wrong during an ecommerce migration?

Most commonly: SEO rankings, when URL redirects and content mapping aren't handled carefully; customer account and order history data, when it isn't migrated cleanly; and third-party app integrations (email, loyalty, reviews) that quietly break until someone notices. Ask any agency to walk through their specific migration checklist before you sign.

How long does an ecommerce migration typically take?

A focused Shopify Plus migration for a mid-sized catalog can run 8 to 12 weeks, as Blue Stout and Netalico have both demonstrated in published case studies. Complex enterprise migrations with multiple integrations or multi-region rollouts, like Domaine's work for global brands, more typically take 4 to 9 months.

Is it worth paying more for a boutique, senior-only team over a larger agency?

Often, yes — a boutique agency with senior staff on every project (like Fuel Made or Netalico) can outperform a larger firm that hands your build to junior staff after the pitch. Team seniority and platform-specific track record matter more than agency headcount.
