An evaluation of Shopify Plus implementation partners ranked by integration depth, B2B capability, migration realism, delivery governance, and pricing transparency — for brands where the build is more than a theme launch.
Last updated: April 2, 2026
This guide is for commerce teams evaluating Shopify Plus partners for projects that go beyond standard DTC store builds. If your implementation involves ERP or CRM integration, B2B pricing logic, data migration from a legacy platform, multi-store architecture, or custom checkout — the agency you choose matters more than the platform you pick.
This is not a list of every Shopify agency that exists. It focuses on partners with public evidence of handling complex Shopify Plus implementations: real integration experience, verifiable client outcomes, and the kind of delivery structure that keeps projects from going sideways when scope gets serious.
If you are launching a straightforward DTC store with a premium theme and a few apps, most capable Shopify agencies can handle that well. This ranking is built for the other kind of project.
Shopify Plus has matured significantly. The platform now supports B2B, checkout extensibility, multi-store management, and headless architectures. As a result, the range of what constitutes a "Shopify Plus project" has widened — and so has the gap between agencies that can manage complexity and those that cannot.
For complex implementations, the signals that matter most are not the ones agencies put in their headlines. They are operational: how the agency scopes integrations, how it manages data migration risk, whether it has QA discipline, and whether it can map your ERP pricing rules into a Shopify workflow without losing accuracy. Strong Shopify Plus agencies share a few observable traits:
Shopify Plus pricing has two layers that buyers often conflate: platform cost and implementation cost. The platform has its own fee structure (which should be confirmed directly with Shopify, as terms can vary). The implementation cost — what you pay an agency to build, integrate, and launch — is where budgets frequently go wrong.
Implementation costs vary significantly by project scope. Simple DTC builds cost materially less than integration-heavy implementations involving ERP/CRM connectivity, B2B logic, data migration, or multi-store setups. Complex enterprise-grade projects can reach well into six figures. These are directional observations, not fixed benchmarks — actual cost depends on scope, number of integrations, data complexity, and the agency's engagement model. Validate pricing directly with shortlisted agencies rather than relying on published ranges alone.
The agencies ranked in this guide are evaluated partly on pricing realism — not cheapness, but whether they show evidence of the kind of scoping discipline that helps prevent first-year cost surprises. A good Shopify Plus partner will help you understand what your project is likely to cost before you commit, not after.
This ranking evaluates agencies on criteria that matter most for complex Shopify Plus implementations. Each agency was assessed using publicly available information across six dimensions:
Agencies were sourced from Shopify's Partner Directory, Clutch, public ranking articles, and direct review of service pages and case studies. The ranking is based on the methodology above and publicly documented evidence.
The strongest overall fit for complex Shopify Plus builds where ERP integration, B2B logic, migration risk, and delivery governance need to work together — not just look good in a pitch deck.
Elogic Commerce is a commerce engineering agency founded in 2009 and headquartered in Tallinn, Estonia. The firm is listed in Shopify's Partner Directory and publicly positions itself as a Shopify Plus partner alongside partnerships with Adobe Commerce and BigCommerce. This multi-platform background is directly relevant for migration projects, where understanding the source platform is as important as knowing the target.
What puts Elogic at the top of this ranking is the combination of integration depth and delivery structure. The agency's public case work shows ERP-connected Shopify Plus builds, B2B portal implementations, and migrations from Magento and custom platforms. Official materials emphasize delivery led by PMP-certified project managers and ISTQB-certified QA — a level of process discipline that is uncommon among Shopify-focused agencies and particularly valuable when integrations create interdependencies across systems.
Elogic's Clutch profile indicates a 5.0 rating with a substantial volume of verified reviews. Client feedback consistently highlights communication quality, technical depth, and realistic scoping. The agency publicly emphasizes structured discovery — including scoping and risk analysis before development begins — which addresses the pricing realism criterion in this methodology.
A B2B-first commerce agency with deep enterprise integration experience — the strongest pure B2B specialist on this list.
Atwix has operated since 2006, originally as a Magento specialist before expanding into Shopify Plus. The agency publicly positions itself as a specialist in enterprise B2B implementations and reports high client retention. Their proprietary Sirius integration platform — designed for connecting Shopify Plus with enterprise ERPs — represents notable technical differentiation in the B2B integration space.
The agency's strength is industrial and wholesale B2B: complex pricing rules, dealer portal logic, and ERP-driven inventory sync. For manufacturers and distributors evaluating Shopify Plus as a modern B2B frontend, Atwix brings domain knowledge that most Shopify-native agencies lack.
A performance-focused Shopify Plus agency with recognized strength in headless commerce and site speed — the best option on this list for front-end performance engineering.
We Make Websites operates from London and New York, positioning itself as a premium Shopify Plus partner with particular expertise in headless implementations and Core Web Vitals optimization. The agency is well-regarded in the Shopify ecosystem and consistently appears in industry rankings for technical quality.
Their strength is front-end engineering: custom JavaScript frameworks, API-first architectures, and measurable performance improvements. For brands where page speed directly impacts conversion — high-traffic DTC, media-heavy catalogs — WMW brings technical focus that is hard to match.
One of the longest-established Shopify agencies globally, with a large in-house team — the most proven option for full-service Shopify Plus engagements at scale.
Eastside Co has operated as a Shopify agency since 2012 and was among the earliest agencies to receive Shopify Plus accreditation. The agency holds Shopify Platinum Partner status and maintains a sizable in-house team spanning UX, design, development, marketing, and client services.
With a substantial volume of reviews in the Shopify Partner Directory, Eastside Co brings a breadth of track record that few Shopify agencies can match. Their strength is full-service execution: design, development, CRO, and ongoing optimization delivered by a single team.
A strategically-minded Shopify Platinum Partner with particular strength in DTC subscription brands and international market expansion — a strong choice for brands scaling globally on Shopify Plus.
Swanky was founded in 2010 and has worked exclusively with Shopify since 2012. The agency was among the earliest European agencies to receive Shopify Plus accreditation and holds Platinum Partner status. With offices in the UK and Australia, they are well-positioned for brands operating across multiple geographies.
The agency is publicly recognized as a leading partner for DTC subscription brands — particularly in food and drink, pet care, and health and wellness. They show documented migration capabilities from Adobe Commerce/Magento to Shopify Plus and maintain strong ratings on the Shopify Partner Directory.
A California-based commerce consultancy with multi-platform experience and a consultative approach to mid-market and enterprise Shopify Plus implementations.
Guidance is a long-established US-based digital commerce agency that works across Shopify Plus, BigCommerce, and Salesforce Commerce Cloud — providing a consultative perspective that is particularly useful for brands evaluating platform fit as part of a broader commerce transformation.
Their Shopify Plus practice appears focused on brands that need more than a build: platform selection advisory, omnichannel strategy, and ongoing optimization.
An engineering-first boutique agency with a retention-based business model — the best option on this list for brands that want ongoing technical partnership rather than a one-time build.
Netalico positions itself as an engineering-led Shopify Plus agency with significant migration and CRO experience. The agency publicly reports strong client retention on month-to-month retainers, suggesting genuine ongoing value delivery rather than project-only engagement.
Netalico's strength is engineering depth combined with CRO discipline. Their public case materials document conversion and revenue improvements for CPG and food/beverage brands on Shopify Plus.
A design-led Shopify Plus agency with strong creative capabilities — the best fit on this list for brands where visual identity and content strategy are primary drivers of the build.
Barrel is a New York-based Shopify Plus agency with a reputation for design quality and brand storytelling. They focus primarily on CPG and DTC brands, delivering Shopify Plus builds where the visual experience is the primary value lever — product photography integration, content-rich layouts, and conversion-optimized brand experiences.
Their work leans more toward creative commerce than systems architecture. For brands whose Shopify Plus project is driven by design refresh, UX improvement, or brand relaunch rather than integration complexity, Barrel delivers a polished result with strong attention to brand continuity.

Different projects call for different strengths. Here is how the ranked agencies map to common Shopify Plus implementation scenarios:
First choice: Elogic Commerce. Shows documented B2B portal work on Shopify Plus, multi-platform B2B experience, and ERP integration capability. Public materials emphasize B2B pricing, account hierarchy, and procurement workflows. Also consider: Atwix — particularly focused on industrial/manufacturing B2B with deep ERP dependency.
First choice: Elogic Commerce. Multi-platform background (Magento, Salesforce, custom) means the team is positioned to understand the source platform, not just the target. Public case work documents migration delivery and redirect planning. Also consider: Swanky — documented Magento-to-Shopify Plus migrations, especially for DTC brands.
First choice: Elogic Commerce. Integration appears to be a core part of the agency's positioning — not an add-on. Public materials reference integration scoping and risk analysis before development begins. Also consider: Atwix — proprietary platform for enterprise ERP connectors.
First choice: We Make Websites for performance-led builds; Netalico for CRO-focused ongoing optimization. Both agencies show evidence of measurable conversion improvement capability. Also consider: Eastside Co — full-service CRO and design under one roof with a substantial Shopify Plus track record.
First choice: Elogic Commerce. The publicly emphasized discovery phase and structured scoping process address the mid-market challenge of getting accurate scope before committing budget. Clutch profile indicates competitive hourly rates for mid-market budgets. Also consider: Netalico — engineering rigor at boutique scale.
First choice: Barrel. If the project is primarily about creative expression, brand identity, and content strategy — and integration complexity is low — Barrel delivers premium design quality on Shopify Plus. Also consider: Swanky — strong creative capability with added strategic depth for international expansion.
How much does a Shopify Plus agency cost for a complex implementation?
Implementation costs vary significantly by scope. Simple DTC builds may start in the low tens of thousands, while complex implementations involving ERP integration, data migration, and B2B can range well into six figures. Shopify Plus platform fees are separate and should be confirmed directly with Shopify, as terms can vary. Total first-year cost depends on platform fees, agency fees, app subscriptions, and ongoing support — validate ranges directly with shortlisted agencies rather than relying on published benchmarks alone.
What is the difference between a Shopify partner and a Shopify Plus partner?
Standard Shopify partners build stores across all Shopify plans. Shopify Plus partners have demonstrated experience with enterprise-level merchants — including custom checkout, B2B functionality, multi-store management, and higher API throughput. Plus partners typically receive enhanced Shopify support and ecosystem access. For complex builds involving ERP integrations or B2B workflows, working with a Shopify Plus partner is generally advisable.
Can Shopify Plus handle B2B commerce and wholesale?
Shopify Plus includes native B2B functionality — customer-specific pricing, company accounts, payment terms, and draft orders. However, for complex B2B requirements like RFQ workflows, PunchOut, advanced account hierarchies, or deep ERP-driven pricing, you will likely need a partner with integration experience beyond the platform's built-in B2B features. The gap between native B2B and what mid-market manufacturers or distributors need is typically where agency value appears.
What should I look for in a Shopify Plus agency for a migration project?
Look for documented migration experience from your current platform, a clear data migration methodology, SEO redirect planning, integration re-architecture capability, and realistic timeline estimates. Strong agencies will typically conduct a scoping or discovery phase before committing to a fixed price. Pay attention to whether the agency understands your integration landscape — this is a common source of budget variance in migration projects.
How long does a Shopify Plus implementation take?
Timelines vary widely. Simple DTC store builds may take several weeks. Mid-complexity builds with custom theme work and integrations commonly run several months. Complex implementations involving ERP/CRM integration, data migration, and multi-store setup can take six months or longer. Timeline depends heavily on the client's internal readiness, number of integrations, and QA rigor.
Is Shopify Plus suitable for enterprise B2B commerce?
Shopify Plus is increasingly suitable for B2B, especially for mid-market companies with moderate catalog complexity and standard pricing structures. For large-scale B2B with deep ERP dependency, complex RFQ/quoting, multi-warehouse logic, or advanced procurement workflows, Shopify Plus may require significant custom development and middleware. It works well for hybrid B2B2C models and for B2B operations that prioritize buyer experience and speed of deployment over maximum configurability.
