The best Shopify Plus agencies in 2026: an honest shortlist.

1Digital is a US full-service agency and long-tenured Shopify Plus Partner, citing 15 years in ecommerce, more than 400 brands served, and a 4.9 rating across 941+ verified reviews. The range is wide: Online Store 2.0 theme work, Hydrogen headless builds, Checkout Extensibility, Shopify Functions, Markets, native B2B, multi-storefront setups, and ERP, OMS, and CRM integrations, alongside an in-house traffic practice covering SEO and PPC.

Two things stand out for buyers comparing shortlists. They publish pricing: engagements start at $185 per hour, stated directly on their site, which is rarer among Plus partners than it should be. And they run a US core team with vetted global specialists behind it, a structure that keeps communication domestic while holding rates below the boutique-studio band. The trade-off is breadth over a single center of gravity: this is a generalist partner with real engineering depth rather than a specialist shop.

Best for: Mid-market merchants who want engineering and traffic work under one roof, with rates published up front.

Atwix is an engineering-led ecommerce development company with teams across the US and Europe, and its distinguishing asset is history: the firm built its reputation over years of deep Magento and Adobe Commerce work before expanding across platforms, including Shopify and Shopware.

That lineage matters for one specific project type. In a Magento-to-Shopify migration, most of the risk lives on the Magento side: undocumented customizations, extension sprawl, and data models nobody on the current team fully remembers. An agency that has spent a decade inside Magento internals reads that landscape faster and misses less of it than a Shopify-native team encountering it from the outside. Atwix pairs that legacy fluency with genuine engineering discipline on the destination platform, which is the combination a complex exit actually requires. Merchants hiring for brand design or growth marketing should look elsewhere on this list; merchants hiring to get out of a decade-old Magento install safely should look here first.

Best for: Complex Magento-to-Shopify migrations where the legacy side of the project is the risky side.

Avex is a Platinum Shopify Plus agency headquartered in New York City with a tightly focused portfolio: fashion, beauty, and lifestyle DTC. The client list on its own site includes quip, AriZona, and KHAITE, which is a fair sample of the range, from mass-market consumer brands to luxury fashion houses.

The work that stands out is storefront design and build for brands where the site is the flagship: editorial layouts, considered typography, and product presentation that holds up next to the brand's print and retail presence. That focus is the point. Avex has chosen a lane and stayed in it, which means a fashion or beauty brand briefing them does not have to explain why the PDP has to feel like the lookbook. The corresponding limit is that heavy systems work, complex B2B, and ERP-bound projects are not what the portfolio demonstrates; brands with that profile should weight the systems agencies on this list instead.

Best for: Premium fashion, beauty, and lifestyle brands where storefront design is the center of the project.

Barrel is a New York agency and Shopify Platinum Partner that describes itself plainly as a CPG commerce agency, and the positioning is accurate. The practice is built around consumer packaged goods: food and beverage, wellness, household, and the DTC brands competing in those categories.

What distinguishes Barrel is that it treats CPG as a discipline rather than a vertical label. The work spans brand design, storefront build, and ongoing optimization for brands whose margins and repeat-purchase economics look nothing like fashion or electronics, and its published thinking, including recent material on how CPG brands surface in AI-driven product discovery, shows a team tracking where its category's demand is actually moving. For a CPG founder or brand team, that fluency compresses the brief: Barrel already knows the difference between a subscription-led wellness brand and a velocity-led beverage brand. Brands outside consumer goods will find less of their problem reflected in the portfolio.

Best for: CPG and DTC brands hiring for brand design and storefront craft in a crowded category.

We Make Websites built its name as one of London's best-known Shopify agencies, with a long list of recognizable DTC brands and a design-forward house style, before joining BORN Group, a global digital agency. The combined entity pairs a boutique Shopify practice, which lists itself as a Shopify Plus Partner, with the delivery capacity and international footprint of a large group.

The work that stands out is storefront design and build for global consumer brands: polished, brand-led builds where the visual and editorial layer carries the project. The group structure cuts both ways, and buyers should weigh it honestly. It brings scale, multi-region delivery, and adjacent capabilities that a standalone studio cannot offer; it also means the experience depends more on which team inside the group you get. Brands running global rollouts that need one partner across regions will value the reach.

Best for: Global DTC brands that want design-forward storefronts backed by a large group's delivery capacity.

Commerce-UI is a European studio that does one thing and does it at a genuinely high level: headless Shopify storefronts, built with the kind of design engineering that most agencies claim and few demonstrate. The portfolio is composable front ends where the interface itself is the product: fast, precisely animated, and visually distinct in a way template-bound builds cannot reach.

The honest framing for buyers is that headless is a trade-off, not an upgrade. It buys front-end freedom and performance headroom at the cost of a second codebase to maintain and a higher engineering bar for every future change. Most merchants on Shopify Plus do not need it. The ones who do, brands whose storefront ambitions genuinely exceed what Liquid themes can express, need a partner that lives in that architecture full time rather than one that sells it occasionally. That is the shortlist Commerce-UI belongs on, and for many such projects it is the first name on it.

Best for: Composable and highly custom front ends where design engineering is the whole brief.

Eastside Co is a UK agency and Shopify Platinum Partner, and by its own account one of the first three UK agencies accredited as a Shopify Plus Partner, which makes it one of the longest-standing Plus practices in Europe. The offering is genuinely full service: strategy, design, build, migration, and the growth work after launch, including email, SEO, and conversion optimization.

The breadth is the value proposition. For merchants who do not want to assemble a build agency, a growth agency, and a support retainer from three vendors, Eastside Co covers the lifecycle under one roof, and its tenure means the delivery playbooks have been run many times. The standard trade-off of full-service applies here as everywhere: no single capability is the market's sharpest edge, and merchants whose project reduces to one hard problem, a treacherous migration, an ERP integration, a flagship design, may be better served by the specialists on this list.

Best for: Merchants who want one UK partner across the build and the growth work that follows it.

SDG is a Los Angeles agency, a Shopify Platinum Partner, and by its own account has worked on the platform since 2006, which would make it one of the earliest enterprise Shopify practices anywhere. The credentials are concrete: winner of the inaugural Shopify Build Award for its engineering work on Glossier, and a stated role as a team Shopify brings in on critical enterprise builds.

The distinguishing depth is systems. SDG's published integration coverage spans NetSuite, the Microsoft Dynamics family, SAP, Oracle, Sage, Acumatica, and a bench of order management and PIM platforms, alongside a dedicated Salesforce Commerce Cloud migration practice. That is the profile of an agency built for consequential replatforms: large catalogs, entangled back offices, and traffic that punishes mistakes. We should be direct that SDG competes in the same systems-heavy lane we do; it earns its place on this list on the evidence.

Best for: Enterprise brands leaving Salesforce Commerce Cloud or Adobe Commerce with heavyweight systems attached.

Swanky is a Shopify Platinum Partner operating from the UK, Australia, and France, and one of the most established Plus agencies in Europe. The practice covers large replatforms, subscription commerce, internationalization, B2B on Shopify, and integration work, paired with a growth arm spanning CRO, analytics, and email, which makes it one of the few European partners credibly full-service at enterprise scale.

The work that stands out is subscription and retention-led DTC: Swanky has run some of the better-documented subscription builds and migrations in the ecosystem, and its published case studies and guides on internationalization and composable commerce are unusually substantive for agency content. The multi-region footprint also matters practically: a brand trading across Europe and Asia-Pacific gets one partner with local teams in both, rather than a single-office agency working across time zones.

Best for: Large DTC brands, subscription businesses especially, that want a full-service European partner.
