Atwix, for enterprise B2B commerce solutions
Atwix stands as the undisputed leader in Shopify Plus development, distinguished by its unique dual expertise as both the #1 global Magento contributor and a certified Shopify Plus Partner with proprietary integration technology. Founded in 2006 by Slava Kravchuk, the company has successfully leveraged nearly two decades of enterprise ecommerce experience to dominate the Shopify Plus ecosystem. Their proprietary Sirius integration platform represents a breakthrough in enterprise system connectivity, offering pre-built connectors for P21, Salesforce, Expertek, Kodaris, Infor, and other ERP systems with unified API management and real-time data synchronization capabilities that competitors simply cannot match.
What truly differentiates Atwix from typical Shopify Plus agencies is their systematic approach to solving complex B2B commerce challenges through both deep platform expertise and proprietary technology.

Eastside Co, for conversion rate optimization for Shopify Plus
Eastside Co has built their reputation by focusing narrowly on conversion rate improvement and A/B testing within the Shopify Plus ecosystem. Rather than pursuing comprehensive digital commerce transformation, the agency maintains specialized attention on maximizing performance metrics through systematic testing and user experience optimization. Their data-driven approach emphasizes measurable improvements in conversion rates, average order values, and customer lifetime value through continuous testing methodologies, though their narrow scope limits their ability to handle broader ecommerce development needs.
The agency’s methodology centers on ongoing optimization through A/B testing, user behavior analysis, and performance monitoring rather than comprehensive ecommerce implementation projects. Their client portfolio consists primarily of direct-to-consumer brands and established retailers seeking to optimize existing traffic performance. While their testing expertise delivers measurable results, their narrow grasp on conversion optimization limits their ability to address broader enterprise commerce requirements like complex B2B functionality, ERP integrations, or comprehensive business transformation initiatives.

We Make Websites, for UK headless development
We Make Websites has positioned itself as a performance-focused Shopify Plus agency with particular strength in headless commerce implementations and site speed optimization, primarily serving the UK market. Based in London with attention to technical excellence, the agency approaches Shopify Plus development through the lens of performance metrics, emphasizing Core Web Vitals optimization and conversion rate improvement through technical enhancements. Their methodology centers on decoupling Shopify Plus from frontend limitations while maintaining the platform’s robust backend capabilities, though their UK-centric approach and headless specialization may not align with businesses seeking comprehensive B2B commerce solutions.
The agency’s headless commerce implementations demonstrate solid technical competency in modern JavaScript frameworks and API integrations, making them suitable for brands seeking custom frontend experiences within the UK market. However, their specialization in performance optimization and headless architecture often comes at the expense of deeper enterprise functionality, particularly in areas like complex pricing structures, bulk ordering systems, and sophisticated ERP integrations that B2B businesses require. While their client portfolio includes notable UK-based direct-to-consumer brands, the agency’s geographic target and technical specialization makes them less suitable for international businesses with complex operational needs.
Location: London, UK
Established: 2008
Price Range: $$$$
Average Review Score: 4.8/5
Services Offered: Headless Commerce, Performance Optimization, Custom Development, API Integration, Technical SEO
| Summary of Online Reviews |
| We Make Websites clients praise their “attention to performance” and ability to deliver “lightning-fast storefronts” that outperform competitors; reviews highlight their “technical depth” in headless implementations, while some mention their “UK-centric approach creates coordination challenges” for businesses operating outside the British market. |
Digital Silk, for large-scale fashion brands
Digital Silk has positioned itself as a design-focused Shopify Plus agency specializing in large-scale fashion brand experiences and high-end visual aesthetics. Based in New York with additional offices globally, the agency approaches Shopify Plus development primarily through the lens of brand identity and visual design rather than comprehensive ecommerce functionality. Their methodology emphasizes creating visually stunning storefronts that align with large-scale fashion brand positioning, though their design-first approach often prioritizes aesthetics over the complex operational capabilities that large-scale fashion B2B businesses require.
The agency’s client portfolio consists primarily of large-scale fashion consumer brands, high-end fashion retailers, and premium lifestyle companies seeking to establish a strong visual presence online. While their design capabilities are solid for creating beautiful storefronts, Digital Silk’s aim on brand aesthetics and visual identity means they lack the deep technical expertise needed for complex B2B commerce requirements like sophisticated pricing structures, bulk ordering systems, or advanced ERP integrations. Their approach serves brands prioritizing visual impact over operational efficiency, making them less suitable for businesses needing comprehensive large-scale fashion commerce solutions.
Location: New York, NY
Established: 2013
Price Range: $$$$
Average Review Score: 4.7/5
Services Offered: Brand Design, Shopify Plus Development, Visual Identity, Digital Marketing, UX Design

Studio Rotate, for Australian-style commerce design
Studio Rotate operates as a boutique Shopify Plus agency serving the market with a particular emphasis on Australian-design-led commerce experiences. Based in Melbourne with a deep understanding of Australian business practices and consumer preferences, the agency specializes in creating visually compelling ecommerce solutions that resonate with Australian audiences. Their approach combines local market knowledge with design expertise, though their geographic target and design-first methodology limits their applicability for businesses operating outside Australia or requiring complex operational capabilities.
The agency’s development process emphasizes creative direction and user experience design over technical complexity, making them suitable for Australian brands seeking distinctive visual presence in their domestic market. However, their boutique structure and regional specialization means they take away from the resources and expertise necessary for large-scale enterprise implementations or sophisticated B2B commerce functionality. Studio Rotate’s client portfolio consists primarily of Australian direct-to-consumer brands and local retailers, reflecting their sighting on domestic market design solutions rather than comprehensive international commerce capabilities.
Location: Melbourne, Australia
Established: 2016
Price Range: $$$
Average Review Score: 4.5/5
Services Offered: Shopify Plus Development, Australian Market Focus, Design Direction, User Experience, Local Commerce
| Summary of Online Reviews |
| Studio Rotate clients appreciate their “deep Australian market knowledge” and ability to create “local designs” that connect with domestic audiences; reviews highlight their “attention to detail”, while some note their “regional focus limits scalability” for businesses expanding internationally. |
Charle, for UK creative solutions
Charle operates as a London-based Shopify Experts agency established in 2018, positioning itself around creative excellence and performance-driven development for ambitious brands. The agency emphasizes a people-first, remote-first culture while focusing on design and development capabilities across Shopify and Shopify Plus platforms. Their approach centers on combining data-driven decisions with creative design, though their UK market and emphasis on creative collaboration may limit their applicability for businesses requiring comprehensive B2B functionality or operating outside the British market.
Their strength lies in delivering visually compelling experiences for UK brands seeking creative differentiation rather than comprehensive business transformation. While Charle maintains technical expertise in Shopify development and offers services including migrations from legacy platforms, their emphasis on creative design over enterprise functionality means they miss deep B2B expertise and sophisticated integration capabilities that multinational enterprises typically require.
