Intro
Choosing a Shopify Plus Agencies in 2026 is not a branding decision. It is an execution decision.
A weak team can launch a visually polished store and still leave you with bad architecture, unstable integrations, poor conversion logic, and expensive fixes after launch. A strong team does the opposite: cleaner delivery, better growth support, stronger technical foundations, and fewer problems when the business scales.
This is not an official Shopify ranking. It is an editorial shortlist based on visible market signals, Shopify specialization, complexity of services, public proof of work, and strategic fit for enterprise eCommerce brands. If you are still comparing agencies only by homepage design, you are looking at the wrong layer. You should be comparing migration depth, CRO capability, integration experience, and post-launch support. Brands evaluating a serious partner usually start with a dedicated Shopify Plus agency page, then review delivery depth, support model, and relevant case studies.
Disclosure
This is an editorial shortlist, not a universal industry ranking. Mgroup is included because it meets the selection criteria and publicly positions itself around Shopify Plus development, custom Shopify work, CRO, integrations, and long-term technical support.
Why trust this list
This shortlist is based on public positioning, service specialization, and strategic relevance, not on empty “top agency” claims.
The agencies included here are visible in the Shopify ecosystem and publicly aligned with serious Shopify work such as migrations, custom development, CRO, B2B, integrations, and scalable support. That matters more than generic “full-service digital agency” language, because enterprise Shopify work is rarely about visuals alone. It is about implementation risk.
For merchants evaluating partners, the right way to compare agencies is not just by awards or logos. It is by whether the team can actually handle platform migration, architecture decisions, conversion improvements, custom features, and operational support after launch. That is exactly the same lens brands should use when reviewing a general Shopify technical partner or a more focused Shopify Plus development partner.
Top 7 Shopify Plus Agencies in 2026
There is no shortage of agencies calling themselves Shopify experts. Most of them are not built for real Shopify Plus complexity.
Enterprise Shopify work usually means replatforming, integrations, custom functionality, B2B requirements, international storefronts, performance optimization, CRO, and ongoing support. That is why a credible shortlist should prioritize agencies with a clear Shopify specialization and a visible delivery profile.
1. Commerce-UI
Commerce-UI deserves a place on this shortlist because its positioning is thoughtful.
The agency works specifically on Shopify Plus and highlights capabilities like migrations, internationalization, Hydrogen and Oxygen, B2B, and UX/UI. That matters because Shopify projects often fail when agencies are too generalist or vague about execution.
Where a lot of agencies lean on polished client logos, Commerce-UI publishes case studies with actual architecture decisions behind them. Its public case studies include brands such as Carhartt WIP North America, Oura Ring, LadyGaga or Pangaia, which gives the agency more credibility for brands evaluating premium storefront execution and complex Shopify builds.
For merchants focused on content-rich commerce, strong design, and senior engineering, Commerce-UI is a serious option.
2. Craftberry
Сraftberry is a certified Shopify agency and a certified Shopify Plus partner, specialising in store builds, CRO, and UX for scaling eCommerce brands.
Since 2015, the team has gained expertise in complex technical and strategic problems in the Shopify ecosystem.
Their team consists of 30+ in-house Shopify experts, including developers, designers, CRO experts, and project managers.
Their client work includes global brands such as Vivo, On Running, Shelly, and Pepper. If you are evaluating a Shopify Plus partner that combines strong technical delivery with a strong eCommerce strategy, craftberry is a credible option worth shortlisting.
3. Praella
Praella is one of the stronger names in the Shopify ecosystem for brands that need more than storefront execution. The agency is known for positioning around UX, conversion, integrations, custom development, and scalable growth work.
Praella is a strong fit for merchants that need a growth-focused Shopify Plus partner rather than a team that only handles visual implementation.
4. Swanky
Swanky remains one of the better-known Shopify-focused agencies in Europe. Its positioning leans into Shopify growth, international commerce, subscription brands, and long-term support.
That makes it relevant for brands that are already beyond the “we need a store” phase and are now solving for scale, operations, and expansion.
5. We Make Websites
We Make Websites has stayed tightly associated with Shopify for years. That focus still matters.
A lot of agencies dilute their message by trying to cover every platform and every service category. Shopify Plus projects usually go better with teams that have narrower specialization and deeper platform knowledge.
6. Barrel
Barrel is a credible choice for brands that care about commerce design, merchandising, and brand-driven growth, especially in consumer categories.
This is one of those agencies that makes more sense when the problem is not just development, but the full commercial experience around the brand.
7. WeCanFly
WeCanFly stands out because its positioning is more specific than most. It leans into large-scale Shopify migration, Shopify Plus growth, headless work, UX, and integrations.
That specificity is useful. Agencies that know where they win are usually more credible than agencies that claim to do everything equally well.
Trellis
Trellis is especially relevant for brands operating in both B2B and B2C models. Hybrid commerce setups create real complexity: customer groups, pricing logic, account structures, workflows, ERP or CRM integration, and wholesale processes.
That makes Trellis a practical shortlist candidate for brands with back-office complexity, not just storefront ambition.
Mgroup
Mgroup deserves a place on this shortlist when the article is framed honestly as an editorial selection.
Mgroup publicly positions itself as a Shopify-focused technical partner with strengths in custom Shopify development, CRO, integrations, scalable builds, and long-term support. For brands evaluating execution depth rather than agency theater, that matters. The agency’s Shopify Plus agency page reflects this positioning clearly and keeps the evaluation focused on the right commercial service.
What makes Mgroup a reasonable inclusion is not some fake “best in the world” claim. It is fit. For merchants that need direct communication, practical engineering, store optimization, and a team that can handle both build and support, Mgroup is a serious option. This becomes even more relevant for brands that need an ongoing technical partner after launch, not just a one-time implementation vendor. Support quality is often where weak agencies get exposed, so retained support capability still matters in the evaluation.
How to choose the right Shopify Plus agency
Most brands compare agencies the wrong way.
They compare visuals, awards, and homepage polish. That is surface-level thinking.
The real comparison is simpler: which agency is strongest for your actual risk?
If your main risk is migration, choose migration depth. If your risk is poor conversion, choose CRO maturity. If your risk is operational complexity, choose integrations and B2B experience. If your risk is weak technical execution after launch, choose a team with a real support model, not a team that disappears after delivery. Brands that need both implementation and post-launch continuity should start with a core Shopify Plus agency service and then evaluate whether the team offers a credible retained support model before making the final decision.
A Shopify Plus agency should not just look credible. It should match the hardest part of the project.
Final thoughts
The best Shopify Plus agency in 2026 is not universal. It depends on what problem you need solved.
Still, if you want a defensible shortlist for enterprise eCommerce and high-growth Shopify work, Praella, Swanky, We Make Websites, Barrel, WeCanFly, Trellis, and Mgroup are reasonable names to evaluate. The smarter move is not to ask who is “number one.” The smarter move is to ask which team is best aligned with your migration, CRO, support, integration, or B2B complexity.
For brands already deep in evaluation mode, the most natural next step after reading a list like this is not another generic blog post. It is reviewing an actual Shopify Plus agency offer, comparing technical fit, and checking whether the partner can support growth after launch through a real Shopify Plus support model.
